Control frogs

Adult frogs that live on land is a dangerous predator for the fish fry. In the tadpole, tadpoles and young frogs, toads compete with fish food and the room in which to live so that reduces the oxygen dissolved in water and multiply the remainder of metabolisms.
Adult frogs were found to prey on the seeds of hatchery fish in the pond and the pond and in the fields if the seeds are kept in the rice fields. Seeds of fish and large fish are often swallowed by a hungry frog. In addition to seed and large-sized fish, frogs also prey on fish eggs to be hatched, so the presence of frogs in the pond
seeding and separation is very detrimental to fish farmers.


as carnivores, frogs have a wide mouth that serves to facilitate the capture and swallow prey. Viewed from the color of the body, green frogs
prefer to lurk around the body or green plants as a disguise. At the stalking prey, frogs can survive long enough in silence, without moving. In terms of capturing prey, toads tend to prefer waiting for a victim who approached him rather than chasing back and forth.
If at the hatchery and nursery ponds found in frogs, the frogs must be controlled as early as possible. Effort to control the frog in the pond seeding 'or nursery that is not too wide so easy. The difficult part is in the hatchery business units large enough. Because, until now there has been no effective effort to eradicate the frogs. Frog poisoned with chemicals will adversely affect the surrounding environment and is strongly discouraged. There are three kinds of mechanical control is recommended, namely: infrastructure repair pool, cleanliness of the location control, and disposal of the eggs.


 Improve Infrastructure Pool

The existence of frogs around the pool area is generally caused by two things, namely food availability factor of the form factor and fish seed water as a medium for laying eggs, because in the course of his life he needs water to incubate eggs and raise the tadpoles, tadpoles and young frogs.
From observation, the seed-filled pond carp and African catfish was visited more than a frog pond filled with carp and tilapia seed. Nature of carp seed in the night
who likes to be on the surface of the water and pulled up toward the ridge or the nature of the seed of the African catfish actively feed at night and often to the edge to attract frogs to ambush him. While carp and tilapia at night rather stay in the middle of the pond and are rarely at the edge of the embankment. Toads prefer foods and willing to move closer to the edge of the embankment.
To control the presence of frogs is highly recommended because the brick edge of the pond was a frog with a concrete embankment will be difficult to find a good seat for stalking prey. If he had already entered into the pool, he can not get out again. Toads that do not have perches usually not be successful prey fish.
At the time of dike repair, try flattening the embankment with no gaps that could be used to place a surveillance frogs. It would be better if the dike is given a plastic coating. Or 50 cm from the dike towards the middle of the pond was given a plastic fence so that fish can not get to the edge of the embankment. Vice versa, frogs and eels can not enter the space occupied by fish ponds.

 Controlling Cleanliness Location
Place a clean, less suitable for frogs for prey, because it is less favored by the victim who was also looking for food or rest. Therefore, it is advisable to control weed growth around the dike, or who, stuck into the pool. Location of the many bushes around the pond
grassy ditches and rice fields that can become a frog hangout at noon.
 Discard Eggs from Swimming
Control activities by removing the interference frog eggs are also highly recommended. Eggs that will hatch already causing effects as discussed earlier. To more easily, use seser to collect eggs into a bowl. Further waste eggs on the ground so as not to be hatched.
The most accurate way but it takes time and patience is the eradication of toad mechanically. There catching frogs in the pond and then kill or move to another place. Besides, if it finds a frog egg to immediately dispose of and action on tackling this is done routinely. Eggs can be diserok with scoopnet (small tangguk) of gauze fabric. Eggs are removed from the water will die if exposed to direct sunlight.
