Sharks for carnivorous fish, larval feeding rotifers, branches and horns; grow to 2 cm after the beginning of predatory fish and shrimp fry, small insects, Southeast Asia, artificial hatcheries in the breeding of pangasius, carp feeding fish flowers. Therefore, in the artificial culture of fish species before the pond water should be cultivated with a certain number of micro-organisms, and put some appropriate fish flowers, to give the fish species with sufficient bait, to prevent each other due to insufficient bait and cannibalism. Fish species enter the big pond after centralized thickening, and can continue to feed fish fry (or shrimp fry) of suitable size until they are raised; they can also tame chilled miscellaneous fish during the thickening stage of fish species until they are raised. Shootshell fish are usually stationary underwater, swim less, consume little physical energy, full of a meal can be many days without food, feed coefficient of about 5 or so. The daily feeding amount is about 3% of the weight of the fish, divided into morning and evening meals, shootshell fish are frequently active at night, so the feeding amount in the morning accounted for 1/3, night accounted for 2/3. Chilled small mixed fish as feed, the fish seed stage should be beaten into fish paste splashed in the water. Fish species into the large pond culture, fish paste to the appropriate amount of flour and eel material mixed into a mass; into the breeding in the late stage can be cut into granules, blocks. Feeding needs to set up a fixed food table, food table can be made of bamboo and 1 meter × 1 meter square netting, placed in the pond bottom around, regularly raised to the surface to check and observe the amount of fish food and fish health, growth rate and discretionary feed increase, decrease, as well as clean up the residual bait
