Frogs are omnivorous animals, in which plant food only accounts for about 7% of the diet, and animal food accounts for about 93% of the diet. They mainly feed on insects, such as algae and phytoplankton, as well as insects such as Lepidoptera, Coleoptera, Hemiptera and Diptera. Moreover, frogs often live in rivers, mainly in weeds near ponds, and generally breed in the middle and late April of each year.
Frogs are amphibians of Chordata, Amphibia, Anura and Ranidae. Their body length can reach 10 cm, their skin is rough, covered with warts, and their backs are yellow-green with irregular markings. Frog's ventral surface is white, with horizontal spots on its front and rear limbs, round toes, full webbed toes, thick front legs and well-developed finger pads, which are gray. The adult frog has no tail. They lay eggs in water, most of them are fertilized in vitro, hatch into tadpoles and breathe through gills. After the mutation, adults mainly breathe through the lungs and skin.
Matters needing attention in raising frogs
The density of frog breeding should not be too high. If the breeding density is too high, it is easy to compete for food or fight, and the pollution to the breeding environment is also relatively large. It is best to raise about 20 to 50 frogs per square meter. In the process of breeding frogs, we should pay attention to separate ponds, observe the growth of frogs frequently, and adjust the density scientifically according to the growth of frogs. Frogs must be grouped according to their strength to facilitate later fattening.
Frogs have high requirements for water quality, so strict management should be carried out in the process of breeding. If the open-air pond is used for stagnant water culture, it is necessary to change the water frequently. If it is live aquaculture or flowing aquaculture, it is necessary to appropriately increase the speed of water flow to improve the water quality.
