Cultivation of Frogs, Amphibians of Economic Value

Frogs are amphibians that have economic value. Generally these animals are found in rice fields, swamps, or riverbanks. Usually frogs live in groups. Male frogs will sing a song together to invite the female to mate.

This habit often occurs during the rainy season. People often look for frogs in the fields for their own consumption or to sell to the nearest market. However, for large-scale commercial needs, the demand for frogs can be met by cultivating frogs.

Cultivation of frogs starts from choosing the parent, doing spawning, hatching eggs, breeding to enlargement.

1. Choose parents

Parent female and male frogs are distinguished by ear holes with eyes, vocal cords, or finger membranes. The selected female parent must be separated for two days to stimulate her partner's lust.

2. Spawning

The process of spawning frogs in ponds can mimic the spawning process in their natural habitat. Spawning ponds are made with a size of 3 m × 3 m. The pond is given a paranet fence about 1-1.5 m high to prevent the frogs from escaping.

Spawning ponds are given water plants such as water hyacinth or lotus so that frogs are comfortable laying eggs in the pond. Taro is planted on pond embankments as insect traps. The water supply to the pool must be smooth through the sluice gate. In addition, the pond must be equipped with a drum filled with water to create artificial rain.

Before being used, pond embankments are given manure/compost first so that many insects come. For concrete pools, it is enough to clean the pool and then put the dirt into the sack. Furthermore, the sacks are floated on the surface of the water for 3-5 days until the pond water contains a lot of natural food.

The spawning process generally takes place at night, then the next day some eggs are seen. Eggs should be immediately transferred to the hatchery.

The hatchery pond area is about 3 times the spawning pond area. This aims to provide sufficient space for the tadpole. The pond must be a cement tub or an earthen pond. In 2-3 days the eggs will hatch. Newly hatched tadpoles do not need outside food.

3. Breeding and maintenance

Breeding local frogs generally takes 2-4 months after stocking. Stocking density 50-100 fish/m2. The feed provided in the form of snails, ground fish, and maggots. Feed is given until the frog looks full. For the enlargement period, the feed given is almost the same, the feed can be mixed into a paste or pellet form. Raised frogs can be harvested after 4-5 months after rearing.
