Stone frogs (stone clams are a type of frog) are large frogs that mainly feed on animal food. During the breeding process of adult frogs, if the feed is fresh and sufficient, the growth will be fast, the feeding cycle will be short, and the commercial rate will be high. Therefore, during the adult frog breeding stage, sufficient food supply of fly maggots, earthworms and insects must be ensured. The amount of feed depends on the season and the size of the frog. In late spring, early summer and cool autumn, frogs eat a lot, and the amount of feed is generally 10% to 15% of the body weight. From midsummer to early autumn, the frog's food intake decreases, so you can invest less. The size of live food should be enough for the frog to swallow, and it should be fed once a day at 5 to 6 p.m. Bait should be placed on a fixed food table. The food table can be made of wooden boards, generally 1.5m long and 1m wide. It is placed in the pool and the water depth should not exceed the food table. Disinfect food tables every half month.
