Healthy Eating SHRIMP LOBSTER?
Click Here!
Lobster flavor is delicious, is good also for the health?
There are several criteria to determine it.
1. CONTENT OF MERCURY
Some fish such as swordfish, shark, king mackerel and
suspected to contain high mercury levels. When eaten, the
mercury is harmful to the body concerned.
But the reality is the lobster does not have a high mercury content.
Lobster contains some amounts of mercury that is naturally present in all fish.
2. Parasites and viruses
Doctors and also some people think that lobsters contain parasites and viruses.
But they did not see one thing, that all living things as well
contain parasites and viruses.
The key is to cook meat thoroughly before eating.
It can remove all the batteries and germs.
3. ROTTEN eaters
Strong argument that raises questions is the lobster
eating rotten food, and this lead to the assumption that the lobster does not
healthy for the body. But it is simply not true. In fact, as
like the people who do not want to eat rotten meat and stale and
will prefer fresh meat. Likewise with the lobster.
Lobter eat live fish, clams, oysters and crabs.

SUCCESS TIPS CULTURE tiger shrimp
SUCCESS TIPS CULTURE tiger shrimp
1. The choice of location cultivation
Coast is the lowest area of a watershed. As a result, the quality of fresh water in downstream areas or at the location of ponds to be vulnerable to negative influences from upstream areas, such as sediment deposition, shifting pesticides, and industrial pollutants or pollutant household. In other words, no good water management in upstream areas may have a negative impact on downstream areas. This issue shows that the management of coastal areas can not be divorced from management of upstream areas. Therefore, cultivation of tiger shrimp pond development should be supported by the following requirements:
- Embankment constructed outside densely populated and industrial areas.
- Location of ponds rather than nature reserve forest area, forest tours, and production forests.
- Pond has adequate water resources, both quantitatively and qualitatively.
- Pond has qualified irrigation channels so that water is available on a regular basis, adequate, and secure.
- Sources of fresh water are not derived from ground water (drilled wells) due to the use of ground water in the long term can result in losses, namely the occurrence instrusi sea water (sea water infiltration into the fresh waters) that cause a decrease in surface soil.
2. Holding elections
Selected female parent must have the conditions as
follows:
- Weighing more than 50 grams.
- High content of eggs.
- It's cooked eggs (see the gray on the back).
- In a normal body, not disabled.
- Clean from dirt and parasites.
While the male parent requirements are as follows:
- Weighing more than 40 grams.
- Legs second road terlau not large.
- Not aggressive.
- In a normal body, not disabled.
- Clean from dirt and parasites.
3. Main feed
Tiger prawns are nocturnal, meaning active and active foraging at night or in dark atmosphere. Conversely, decreases in daytime activity and more immersed himself in the mud or sand. Shrimps food varies, both in types and composition, depending on age. However, most shrimp are carnivores (animal eaters). Diet includes small animals, such as invertebrate (no vertebrate animals) of water, small shrimp, clams (bivalvae), and small fish.
Shrimp are farmed in ponds can be given a pellet. Parent shrimp require natural foods that have a high cholesterol content derived from shellfish and other crustaceans (crabs). This type of food needed to accelerate the process of egg maturation.
4. Spawning techniques
In nature, young shrimps are found in brackish waters with low salinity, such as in the estuary of the river where a meeting between seawater and freshwater. After sexual maturity, large shrimp would go deep-sea waters clear and calm water conditions and makes the place to breed.
Such conditions are also necessary if the tiger prawns cultivated outside their natural habitat, eg in the hatchery (hatchery) tiger prawns. Tiger prawn spawning actually not much different from the spawning fish.
Sex tiger prawns will be cooked at the age of 1.5 years and are ready to do his duty to reproduce. At that time, his weight reached 90-120 g / fish.
Mating tiger prawns are generally held at night. There is a tendency, when the full moon occurs on a mass spawning tiger prawns which have matured genitals.
Spawning occurs when males release sperm shrimp from the male genitalia (petasma) and then enter them into the genitals (telichum) female shrimps. After the occurrence of direct contact, the female parent will nengeluarkan egg so that fertilization occurs. This fertilized egg will float in the bottom of the deep ocean waters. Furthermore, eggs that have hatched into larvae that will be planktonic (drifting) and will rise to the surface water.
In a single spawning season, a female produces as many eggs 200000-500000 grains. After the eggs hatch, the larvae of tiger shrimp changing its form several times like these:
- Period or the period of the first nauplius larvae shrimp. It lived during the period 46-50 hours and the larvae suffered six times the turnover of skin.
- Zoea period or second period. This period takes about 96-120 hours at which time the larvae have three times the replacement skin.
- Period Mysis or third period. This period takes 96-120 hours and the larvae suffered as much as three times the turnover of skin.
- The period of post larvae (PL) or the fourth period. Tiger prawns reached sub-post larvae stage until 20 levels. When we reach this period, shrimp prefers brackish waters with salinity of 25-35 ppt.
- Period of juvenile or fifth period. Juvenil is the youth who love the shrimp waters with salinity 20-25 ppt. Period of adult shrimp. This period lasted after the juvenile period until the shrimp are ready to breed. Once matured genitals and mature gonads, adult prawns will be back into the sea to spawning. Adult shrimp like brackish waters with salinity 15-20 ppt.

treatment of prawns when the harvest
treatment of prawns when the harvest
prawns are harvested in the pool when the first harvest is usually stored in the nets, shrimp in the net storage carried out in order to sort and count size shrimp shrimp weight.
size of the shrimp harvest is divided into three parts, small, medium, and large sizes. nets to keep the shrimp harvest units should be equipped with aeration, aeration serves to maintain the freshness of the shrimp on the net with the main objective is to supply oxygen to the water. This aeration unit consists of pump, which has given paralon hole. holes on this paralon made to emit water so the water out in paralon and fell into the pond to make waves on the surface of the pond water.

shrimp resilience levels
shrimp resilience levels
Plasticity shrimp as one indicator of shrimp condition is the crucial factor of success of a process of cultivation, especially on the quality of shrimp that will be produced, so that will indirectly also affect the sale price. Simply shrimp resilience level can be interpreted as the ability of the shrimp body (part of the shell / skin with meat) to go back into shape after a power hit from the outside. Shrimp resilience level can also be equated with "fat" or "skinny" a shrimp because these factors closely linked with the consumption rate of shrimp feed itself.
In practical shrimp resilience level can be determined by simply pressing the shrimp's body using the thumb and forefinger and then the pressure is released. In this way it can be determined the level of resilience and condition of shrimp at that time. Shrimp resilience level can generally be classified into 3 categories, namely:
1. Porous, at this level of shrimp in a condition "very thin" and can be categorized in the severe conditions. In this condition if we suppress the body of shrimp, it would seem there is space between the shell / skin with shrimp meat and the shell tends not / old back into shape. If most of the shrimp population in the pond has the same condition, it can be said that the shrimp in the pond is in a serious condition. This condition if not immediately treated could cause a drop in the shrimp population density significantly, because the shrimp are relatively porous but susceptible to the disease also can trigger cannibalism among shrimp in these ponds.
2. Was, at this level of shrimp in the state of "thin". In this condition if we suppress the shrimp's body, then it will feel the skin / shell and shrimp meat together but in a less tough conditions. If most of the shrimp population in the pond has the same condition, it can be said that the shrimp in the pond is on the condition of being.
3. Chewy, the shrimp at this level in the state of "fat". In this condition if we suppress the shrimp's body, then it will feel the skin / shell and the shrimp meat was very tough. If most of the shrimp population in the pond has the same condition, it can be said that the shrimp in the pond is in good condition.
As an effort to obtain the level of ideal plasticity shrimp feed program should be applied to follow the requirements of the shrimp feed itself. Feed programs that are too tight can cause rotten shrimp. On the other hand the feed program can cause too much shrimp in a state of "fat" although good for shrimp, but can lead to over-feeding that trigger accumulation of feed remaining at the bottom of ponds and if this condition is left too long, it can cause problems for the shrimp itself.
Careful observation of conditions at the time of the shrimp feed on the net to check up and at the time of routine sampling is one of the alternative activities that can be done to control the level of resilience shrimp feed programs implemented (linked to Food Conversion Ratio). Based on the above description, the most ideal conditions is the shrimp in a state of "fat" food program that is still controlled in accordance with the requirements of shrimp.

artificial feed for shrimp
artificial feed for shrimp
As in the previous discussion, artificial feed for shrimp feed can be interpreted as made in industrial scale with nutrition and nutritional composition in accordance with the requirements provided for shrimp and food supply in ponds with natural food availability levels have been depleted / exhausted at all. The level of use of artificial feed is different based on the relative scale shrimp farming is applied, as will be described below:
1. In the traditional scale shrimp farming, the use of artificial feed is not / rarely used in the feeding patterns of the application. The use of artificial feed is limited to feed based on the ability of an individual pond management. The materials used in the manufacture of artificial feeding include: bran (bran), corn, flour and fish as a mixture rucah. This type of feed is usually used after reaching the age of shrimp harvested with an estimated population of relatively large shrimp.
2. In the semi-scale shrimp farming-intensive, the use of artificial feed is more focused on anticipating the occurrence of natural food shortages based on the estimated population of shrimp at that time. Artificial feeding is applied not absolute and are more likely incidental.
3. In scale-intensive shrimp farming, the use of artificial feed, especially the industrial scale is absolute as one of the shrimp farming management requirements. Dense stocking a relatively high shrimp is one of the basic ideas to consider. In addition the application of artificial feed is right on the scale intensive shrimp farming can help in estimating the condition and growth of shrimp in the pond
When compared with other types of shrimp feed, and industrial-scale artificial feed characteristics in terms of size and composition of nutritional value it contains. These characteristics made and determined by the manufacturer based on the nature of the industry and the needs of shrimp in the pond.
The size of artificial feed for shrimp is the size of feed pellets in accordance with the needs of the shrimp at the time and under certain conditions. Based on its size, artificial feed outlines usually can be classified into types:
1. Crumble, namely in the form of feed grains powder / fine grain and commonly used in shrimp young age.
2. Pellets, ie artificial feed in the form of small granules to coarse grains and commonly used in adult shrimp until shrimp harvest age.
Besides the size, composition is reviewed on the basis of nutritional content has made the feed formulation that is tailored to the needs of shrimp growth. Nutrients are usually present in the artificial feed such as: carbohydrates, proteins, fats, fiber and some other essential substances needed shrimp. The composition of these nutrients may vary depending on the size of feed and industrial manufacture. Under certain conditions of artificial feed is combined with supplemental materials (including vitamins) to overcome these deficiencies and required by the shrimp in a very much needed.

Shrimp feed
Shrimp feed
Shrimp feed is one of the important parameters in the cultivation of shrimp, because it is a contributor to the cost of production compared to most other parameters (mainly on shrimp cultivation intensive pattern). Referring to the rationale for granted that the perpetrators had knowledge of the cultivation of shrimp feed quality parameters that are not wrong in determining the shrimp feed that will be used.
Mostly the shrimp feed that will be used should be able to accommodate two components namely: (i) shrimp need level, and (ii) the behavior / properties of shrimp. The level of shrimp to feed the need not only include how much the quantity of feed that can be consumed, but also include the nutritional value of ingredients (nutrients) needed for growing shrimp. While behavioral component includes shrimp food habits (type of feed what is usually consumed by the shrimp) and feeding habits (how to eat shrimp feed) so that these components also determine the quality parameters of shrimp feed (discussion related to food habits and feeding habits have been described in the discussion earlier).
Based on the above description, the parameters that can be used in determining the quality of shrimp feed are as follows:
1. Nutritional feed, which contain no nutritional value to feed them. Mostly the existing nutrition in shrimp feed should include: (i) protein, (i) fat (fat), (iii) fiber (fiber), and (iv) the ash was also factors other than moisture feed (feed mouisterize). Nutritional / nutritional value of feed is usually specified by the manufacturer on the packaging, including the production code and expiration date. (This discussion is not going to explain about the meaning and function of each of the elements of nutrition, because it leads to knowledge of nutrition science and nutrition).
2. Solubility level of shrimp feed in the water, the time it takes a feed to be soluble in water. These parameters can also be said as the degree of plasticity (hard or soft) texture of a food, or in other words, the harder the texture of a shrimp feed, feed the late time will be longer, too.
Solubility parameters of feed rate in water is closely related to the shrimp's ability to tolerate the level of resilience in the texture of a food to consumed. If the texture of a food is too hard, usually will not eat shrimp feed and will try to find other food sources. Conversely, if the texture is too soft food, then feed it will be soluble in water without a chance to be consumed by the shrimp.
3. The smell of food. These parameters related to the nature of the shrimp in the search for more food sources rely on the sense of smell. The smell of the feed should be able to provide odor stimuli that can attract the shrimp to consume. If the feed does not have a scent that can attract the feared shrimp feed will be wasted for nothing in the waters and this condition can lead to accumulation of feed remaining at the bottom of ponds.
These three parameters mentioned above are the basic parameters that should be understood by the perpetrators of shrimp cultivation, so that no confusion in determining the product / brand of feed that will be used in the process of shrimp cultivation.

uniformity shrimp
uniformity shrimp
As already explained, in a population of shrimp in ponds in general can be classified into 3 (three), namely: (i) shrimp uniform, (ii) the uniformity of the shrimp were, and (iii) the level of bad shrimp uniformity. In addition to these explanations, the understanding of how management alternatives based on conditions encountered in the field.
Broadly speaking, management needs to be done related to the uniformity of shrimp feed includes program management and water quality management (assumption: benur have used relatively uniform, both size and age). Alternative management of the above conditions are as follows:
1. Shrimp uniform. If the population of shrimp in the shrimp ponds showed relatively uniform size, so technically that management needs to be done is how to maintain these ideal conditions until the shrimp is ready to be harvested in a normal way. Management of the feed program should always follow the shrimp need level and the amount of feed given daily in accordance with the density of shrimp in the pond. In this condition is usually the amount of feed given to show that is always increasing trend based on time (except shrimp in a periodic moulting condition). Feeding programs must be carefully managed on the basis of observations made (by check or sampling Ancho).
In addition to food programs, alternative management needs to be done is the quality of pond water. Usually there is a correlation between the uniformity and quality of water shrimp (assumption: the feed program was implemented as mentioned above), namely: the size of the shrimp will be relatively uniform, if the management of water quality in accordance with the requirements of shrimp. The effort needs to be done in water quality management is how to maintain pond water quality, relatively stable and no fluctuations change the pond water quality. Explanations related to the management of water quality ponds have been described in previous discussions.
2. Shrimp with uniformity level was. In this condition technically manage to do is how to prevent the level of uniformity is not worse and efforts to improve blood circumstances better. Feed program should be reviewed applicable mainly related to the size composition of shrimp feed and the amount of feed given. The composition of the feed size and the amount can be roughly estimated by observation at the time of sampling and check Ancho. Estimated percentage does include the density of each size of shrimp in a population, which can be estimated size of the feed to be used and the amount to be given in a single daily feeding frequency. The composition should be adjusted back by referring to the observations made. If the level of uniformity of shrimp which leads to a better level then the given feed size would be less.
Example: in a population of shrimp in the pond has 3 different sizes, given the feed should consist of 3 types of feed of different sizes to suit all shrimp sizes. If uniformity of shrimp in these ponds was led to a better level, for example, be 2 types of shrimp size, the composition of the feed size should also be given 2 types of feed size. Pond water quality management is carried out under these conditions relatively similar to item no. 1 mentioned above.
3. Level of bad shrimp uniformity. In this condition technically manage to do is how to prevent the shrimp population in the pond is not as drastic shrinking (due process of cannibalism). Programs that need to be applied feed primarily on items such as no explanation. 2, only the size of the species composition of feed used in one feeding frequency will usually be much too. In a more extreme handling, sorting is usually done directly shrimp size during the check Anco or sampling activities at the time (not recommended). Terhdap done sorting shrimp with sizes that are considered too far behind shrimp with normal size, so the expected level of uniformity in the shrimp ponds will be better although the density decreased. Pond water quality management is carried out under these conditions relatively similar to item no. 1 mentioned above.
Alternative treatment above is essentially an effort to maintain, improve and prevent a condition to the level of uniformity in a population of shrimp in ponds can lead to conditions as expected, especially at an optimal output.

As already explained, in a population of shrimp in ponds in general can be classified into 3 (three), namely: (i) shrimp uniform, (ii) the uniformity of the shrimp were, and (iii) the level of bad shrimp uniformity. In addition to these explanations, the understanding of how management alternatives based on conditions encountered in the field.
Broadly speaking, management needs to be done related to the uniformity of shrimp feed includes program management and water quality management (assumption: benur have used relatively uniform, both size and age). Alternative management of the above conditions are as follows:
1. Shrimp uniform. If the population of shrimp in the shrimp ponds showed relatively uniform size, so technically that management needs to be done is how to maintain these ideal conditions until the shrimp is ready to be harvested in a normal way. Management of the feed program should always follow the shrimp need level and the amount of feed given daily in accordance with the density of shrimp in the pond. In this condition is usually the amount of feed given to show that is always increasing trend based on time (except shrimp in a periodic moulting condition). Feeding programs must be carefully managed on the basis of observations made (by check or sampling Ancho).
In addition to food programs, alternative management needs to be done is the quality of pond water. Usually there is a correlation between the uniformity and quality of water shrimp (assumption: the feed program was implemented as mentioned above), namely: the size of the shrimp will be relatively uniform, if the management of water quality in accordance with the requirements of shrimp. The effort needs to be done in water quality management is how to maintain pond water quality, relatively stable and no fluctuations change the pond water quality.

Catfish Gel Could Mean Fresher Shrimp
Catfish Gel Could Mean Fresher Shrimp
AG Illustrated
Although shrimp is the perennial seafood of choice in the U.S., the industry could be more profitable if not for a couple of technical problems in the processing stage.
The issues, which shrimp share with virtually all seafood products, are the short shelf life of fresh and frozen shrimp and the drip loss of frozen shrimp when thawed. Drip loss causes a 10- to 15-percent loss of liquid and a decline in quality.
An effective preservation technique that would keep fresh and frozen shrimp- both wild-caught and fa rm-raised—fresher longer and also reduce drip loss in the frozen and save industry millions of dollars.
Auburn biosystems engineering associate professor Yifen Wang has a study under way to evaluate catfish gelatin as a potential solution to the shrimp industry’s dilemma.
Catfish gel is a new value-added product that, in fact, Wang, fellow faculty member Oladiran Fasina and scientists at Tuskegee and Alabama A&M universities developed recently. The product is an economical, high-quality gelatin that is made from catfish skins and that offers the food and
pharmaceutical industries an alternative to beef and pork gelatins.
In the current study, Wang and collaborators will test several catfish gel/preservative formulations to derermine their effectiveness in extending shelf life and im proving quality when sprayed on shrimp or when shrimp are dipped into it during processing.
If successful , the produce would be a boon not only to the shrimp industry-which includes five west Alabama farm-raised-shrimp producers-but to catfish producers and processors as well.

membrane electron Weapon exterminator Shrimp Virus
membrane electron Weapon exterminator Shrimp Virus
This tool is specifically designed to kill off the virus in shrimp
Shrimp pond land in the north coast of Java Island (Pantura) quality is very bad. In addition to pollution by industrial waste dump and the household, lands in the pond there is also decreased due to the quality of the cultivation of land use often without any improvement. Bath enforce yarn wet, efforts in the cultivation of land is nearly always encounter a failure. Instead of harvest, shrimp, not able to survive more than 20 days.
But for Endi MuchtarUdin, the story of the shrimp. Shrimp farmers from the river is clogged, Pedes District, Karawang regency, West Java this successful break that can not Pantura for shrimp cultivation. Harvested three times in succession, Endi menangguk fate of shrimp farming pond in the location of the previous mangkrak (idle / pond is broken and unused).
More terrible, which developed the type of shrimp old man is part windu (Penaeus monodon), the level of difficulty higher than the cultivation vaname species (Penaeus vannamei). The secret, said Endi, using weapons ME-1 (membrane electron 1)
to fight the virus. This tool is able to kill virus-the virus causes disease in shrimp. Various viruses during this frighten the farmers, such as shrimp White Spot Syndrome Virus (WSSV), Taura Syndrome Virus (TSV), infectious Hypodermal Hemathopoetic Necrosis Virus (IHHNV), Myonecrosis infectious virus (IMNV) and Virus Nervous Necrosis (VNN) will be ditaklukkan .
Shoot virus DNA
Membrane electron is an instrument of high speed electrons that is specifically designed to reduce the amount of virus in water. This tool consists of two parts. The first part is called electron generator (box driver generator electrons) generate a working high-speed electrons. Part two is a layer plating electrode kassa that placed in the pipe paralon. Its function is to create electron-rich zone in the water. Zone generated electrons will bond with the protein on the virus through. So that the water that flows through this zone will be free of the virus.
installed base in the provision of water pipes in the pond and work when the process of water. "The principle is the damage to DNA viruses in the water that will go to the pond," said Endi. How it works, the wall power maximum 75 watts (for 1 unit of ME-1) flowed to the electrode so that the shape kassa membrane electron. Water entering the pond will be managed through a membrane with maximum debit 25 liters of water per second. If there is a virus through, then the DNA to its will ditembak by electrons up to a series of virus damaged.
According Endi, 1 ME-1 unit diameter paralon 6 - 8 inch can be used for the pond area of 5 hectares. Cost of making one unit of ME-1 ranges from Rp 10 million. Hmmmmmm life to 8 hours. or two cycles. But it will be better if every turn of the cycle do not kassa a more cost Rp 500 ribu. This will make the work of ME-1 maximum.
Endi confess, does not alone make itself ME-1, but together with the Central Marine Fisheries Development Cultivation. And brackish water shrimp (BPBPLAPU) Karawang. This is in place. Endi ordinary search of the problem that faces in the cultivation of shrimp.
Sunendar Dede, Head BPBPLAPU states, electrons proven membrane technology capable of tackling the virus. "In place of the stock we have already detected a positive WSSV infected.'s Been with the provision membrane electron and then the water out of the stock to be virus-free," said Dede.
According to him, pond-pond in the area during this BPBPLAPU stated can not be planted more shrimp. However, with the ME-1, now pond-pond may be in the back with satisfactory results. BPBPLAPU using the ME-1 in two different places. In the land-intensive pond system vaname of 4.2 hectares, solid tebar reached 360 thousand, the harvest reached 3.2 tons. While the land area of 2.4 hectares, 75 thousand tebar compact,
system between poly vaname shrimp and seaweed (Gracilaria), 8.2 kuintal can harvest shrimp.
Endi and intend BPBPLAPU parties will continue to refine this ME-1. For example, said Endi, complete with the ME-1 speed, so the frequency of more optimal results.
Bacillus Buntus River
However, Balk Endi and Dede
remind, the success of shrimp farming and windu vaname in pond
mangkrak not only because of ME-1, but should also apply
probiotik system bakterinya taken from a local pond. Endi and BPBPLAPU has also successfully developed
probiotik bacteria that diisolasi's own tambaknya (TROBOS edition 103, April 2008). This bacteria will be able to destroy the excess (leftover)
organic pond so that the causes of quality pond.
In the meantime, the bacteria probiotik successful diisolasi from the pond they are a type of Thiobacillus and Bacillus subtillis. "His name Bacillus buntus river," said Endi joke Pests mention bacteria that diisolasi from tambaknya.
Head of Section Testing BPBPLAPU, Riswan Man says, use probiotik conducted continuously.
Pemberiannya after
1x24 minutes the culture
bacteria. For culture
Bacillus bacteria, BPBPLAPU
using the formula 1 liter
Bacillus, feed 1 kg, 1 kg sugar
and 100 liters of fresh water. Probiotik
Bacillus a role in this
absorbing matrix protein
feed. This means this will probiotik
contribute to the availability of
protein in the pond.
While for Thiobacillus, formula consisting of 1 liter Thiobacillus, nutrition 1 kg, 1 kg of sugar and 100 liters of fresh water. For the last type of a role in reducing the level H, S in the pond and for the bright color of water.
During the preparation of land (before the water filled) probiotik given more. For example BPBPLAPU the pond in the area of 1600 m2, probiotik a given reach 40 liters of culture (a mixture of formula). Meanwhile, when the shrimp have been pond, dose reduced to 15 - 20 liters for the same land.
Besides the use of probiotik, Section Head of Applications Technology Cultivation Bandeng BPBPLAPU, add adang Solihin, in the cultivation of shrimp pond mangkrakjuga will be a success by giving special treatment during drying area. Namely burning straw (or other material) on land to kill bacteria and viruses that have in the pond. This can also be used to increase the element carbon in the pond. BPBPLAPU parties in this case spent about 6 tons of straw for the pond area of 4.2 hectares. According adang, burning straw, especially applied to land that muddy pond.

TOTAL feeding Windu Shrimp
TOTAL feeding Windu Shrimp.
The amount of the feed for maintenance is calculated based on the sampling results. To facilitate hitungannya calculated, the amount of feed given to the following provisions:
1. Shrimp stadia zoea, with the amount of 1.5 ppm + feed plankton.
2. Mysis shrimp stadia, namely the amount of 1 ppm feed.
3. Shrimp post flyblow stadia, namely the amount of 1 ppm feed + nauplii Artemia.
4. Shrimp the size of PL 20 - 5 grams, namely the amount of 25% - 50% of total body weight per day.
5. Shrimp size 6 - 10 grams, namely the amount of 15% - 25% of total body weight per day.
6. Shrimp size from 11 to 15 grams, namely the amount of 8% - 15% of total body weight per day.
7. Shrimp with 20-30 grams of weight, namely the amount of 4% - 8% of total body weight per day.
In addition to accuracy in the amount of feed given frequency also develop an important role in the effectiveness of the use of feed. All this of course should be tailored to the biological nature of shrimp that are kept. Estimation of the number and weight of the sampling shrimp also play a role is very important, because it can determine the quantity of feed must be provided.
In connection with teknolegi semi-intensive cultivation of shrimp and shrimp ponds in the intensive program of the feed can be made, such as table 8.
Food is the largest part of the cost of production and is also suspected to be the determinant factors in the economic value of shrimp cultivation. One of the things that must be taken by the farmers embankment is Feed Conversion Ratio (FCR).
FCR is how much value kg of food provided to the ponds can produce 1 kg of shrimp that are kept in the ponds. FCR value addition influenced olehjenis kept in the shrimp ponds and the quality of food, is also affected by the provision of food programs and environmental management ponds.
Farmers ponds must be careful of the value of FCR, as with improving the value of FCR, other than the production cost can be pressed, FCR also related to speed growth and the basic conditions of ponds. Value FCR bad identic

Terms of the absolute to fulfill the feeding is a good evenly, in the sense that can be cultivated so that one individual shrimp feed to obtain the same with other individuals, so that expected by feeding evenly, growth will be uniform. With natural selection, in line with the length of time maintenance, shrimp, the weak will experience death and shrimp that have a resistance standard will be able to "death to all infidels' and grow well.
How the feed is evenly can avoid the occurrence of competition in the food. If the competition can be avoided, then the nature of cannibalism will be more manageable. Competitive conditions and cannibalism will be more sharply and the size of shrimp when glaring vary. Shrimp have a great ability and the size of the mouth larger than shrimp, prawn, so get more food and grow more rapidly, the shrimp grow increasingly hampered due to get less feed.

A value in the aspects of biology's most important is the value onversi feed (Feed Conversion Ratio). This value is not an absolute figure, because not only determined by the quality of feed, but also influenced by other factors such as type and size of shrimp, the number of spreading density, water quality and the other as described in Chapter VII. The small value of feed conversion, the better the quality of feed, because it will be more economical. To know the value of shrimp feed conversion should be done in the field testing on various types of experiments.

ANALYSIS FISIKA on feed Windu Shrimp
ANALYSIS FISIKA on feed Windu Shrimp
Feed Water Stability is stability in the feed water is an important factor in determining the feed efficiency. Feed the resistance in the water only a few changes in the quality and quantity of feed is the physical requirements, good enough. To achieve this condition is recommended to feed shrimp physically still intact for about three hours in the water.
How to find out is as follows:
1. Before the feed is soaked in water first, conducted chemical analysis.
2. Soaking done in a container with the volume and depth of at least 0.5 m3 and 0.6 m.
3. Water is driven by a strong aerator, causing waves and the amplitude at least 5. Cm.
4. Feed placed in the primary vessel that has a basic level.
5. After soaked 3 - 6 hours, again conducted chemical analysis.
Basically, the more finely the raw materials used to prepare food, physical form will be good also, because it will be mixed better products so that more compact and stable in the water, so relatively easy.

Determination of Water / analysis of shrimp feed
Determination of Water
analysis of shrimp feed
In general, the determination of the water is done with the sap of the oven temperature at 105 - 110 ° C for 3 hours or until a constant weight was obtained. Difference in weight before and after drying is the number of water evaporated. For material that is not heat-resistant heating is done in vacuum oven with a temperature lower. Sometimes the drying is done without heating, the material included in the eksikator with H4 SO2 dense as the dryer to achieve a constant weight.

analysis of shrimp feed
In general, the determination of the water is done with the sap of the oven temperature at 105 - 110 ° C for 3 hours or until a constant weight was obtained. Difference in weight before and after drying is the number of water evaporated. For material that is not heat-resistant heating is done in vacuum oven with a temperature lower. Sometimes the drying is done without heating, the material included in the eksikator with H4 SO2 dense as the dryer to achieve a constant weight.

Tabel 6. Komposisi Komponen Telur Ayam (Chow, 1978)
Telur mentah mengandung zat avidin yang dapat menghambat pertumbuhan, sehingga zat tersebut harus dihilangkan dulu melalui pemanasan sebelum diberikan kepada larva udang. Walaupun demikian, pemanasan dapat menyebabkan pemisahan kuning dan putih telur sebagai akibat denaturasi protein. Untuk mengikat kedua bagian tersebut menjadi pakan yang homogen stabil dalam air, diperlukan penambahan bahan pengikat (binder) yang sesuai dan itu berarti merupakan penambahan biaya. Oleh karena itu, dalam pembuatannya diperlukan metode tertentu dan produk yang dihasilkan harus mempunyai persyaratan sebagai berikut :
a. Mempunyai nilai gizi tinggi dan bebas dari zat avidin.
b. Ukuran dan tekstur produk harus dapat diterima oleh larva udang.
c. Mempunyai ketahanan dalam air (water stability) yang cukup baik.
d. Mutunya tidak cepat menumn karena aktivitas mikroba dalam air.
e. Dapat disimpan dengan baik melalui penyimpanan biasa.
f. Mudah dalam pembuatan.
Prosedur yang dapat digunakan dalam pembuatan mikrokapsul telur yang memenuhi persyaratan tersebut di atas adalah sebagai berikut :
a. Isi telur dimasukkan dalam wadah yang cukup kuat.
b. Telur dikocok kuat-kuat dengan menggunakan blender sampai homogen.
c. Air mendidih (kira-kira 150 cc per satu butir telur) dicampurkan dengan cepat ke dalam wadah dan diaduk merata. Melalui proses ini akan didapatkan suspensi yang mengandung butiran-butiran yang sangat halus.
d. Air dingin ditambahkan ke dalam wadah sampai volume yang dikehendaki. Setiap 50 gram telur mengandung sekitar 12 gram bahan kering.
e. Pemberian pakan kepada larva udang dapat dilakukan langsung dengan sendok atau sprayer.
f. Makanan yang tidak digunakan disimpan dalam wadah tertutup dan ditempatkan dalam refrigerator.
Dalam pakan mikrokapsul telur dapat juga ditambahkan beberapa vitamin dan kalsium yang penting bagi pertumbuhan larva udang, karena kemungkinan telur kurang mengandung zat-zat tersebut. Penambahan vitamin dan kalsium dilakukan selama pembuatan pakan tahap kedua. Selain itu perlu juga ditambahkan bahan yang mengandung karbohidrat tinggi, seperti tepung terigu dan tepung tapioka. Sebelum ditambahkan, bahan tersebut digiling menjadi partikel yang sangat halus terlebih dahulu.
