The conditions can be fed small fish, chilled fish, snails or snails, snails and snails must be cooked and chopped.

Second, the daily management and disease prevention In order to avoid the formation of "bloody" due to excessive water in the later stage of cultivation, each pond should be stocked with 60 stockings and 40 tails.

The pond with inconvenient water source should be started with an aerator to ensure the water-soluble oxygen content of the pond. Sprinkling quicklime regularly can not only regulate water quality, but also play a role in disinfection.
