The invention belongs to the technical field of
aquaculture, and relates to a method for mainly culturing yellow catfishes and carrying out
polyculture on other feeding fishes in a pond. The method is characterized in that a new netting method is designed, various feeding fishes can be cultured in the yellow-head
catfish main culturing pond in a
polyculture mode according to local conditions, and the unit culturing efficiency of the yellow-head
catfish main culturing pond can be improved greatly. The method mainly includes the steps that a purse net is erected in front of a main fish, namely the yellow-head
catfish, feeding
machine according to the feeding area covered by the feeding
machine; preferentially, 80% bait fed by the feeding
machine can fall in a region surrounded by the purse net under the breezeless condition, wherein the purse set is made of
polyethylene, and is 60m in length, 4m in height and 4cm in mesh, dense-net cylindrical
polyethylene net pieces are sewn at the bottom of the purse net, the
diameter of each dense net piece is 6cm, cobblestone are arranged in the dense net pieces as sinkers, the purse net is fixed into a closed circle through bamboo poles, the foot line reaches bottom mud, and the head line is exposed of the water surface by 80-100cm. The invention further provides a coordinated culturing mode and a specific method.
