Fish polyculture is an effective way of high-efficiency breeding. In order to obtain a high yield of polyculture, the following points must be mastered in the technique of feeding.
First, grasp the focus of feeding. Baboon is the focus of feeding, followed by grass carp and so on. In this way, through the nitrogen-enriched nutrients contained in the metabolic wastes of grass carp and grass carp, a large number of plankton can be bred to feed a large number of carp and carp, thereby reducing the cost of polyculture.
Second, enrich your nutrition. To feed high-protein animal feeds, such as fresh snails, clams, fish and shrimp, clams, and by-products of processed meat. At the same time, supplemented with starch-containing plant foods, such as soybeans, corn, sorghum and so on.
Third, pay attention to feeding methods. Feeding snails to young larvae requires shredding of shattered shells. The amount should be quantified by 5% to 10% of carcass weight and the degree of feeding. If meat processing by-products are fed, they must be boiled and sun dried to deteriorate by corrosion. Each feeding amount should be 5%-10% of the weight of the wolfberry. Generally, the feeding should be done once a day, but it should also be based on the water temperature. Activities and food intake were strong and weak but increased or decreased.
Fourth, artificial mixed bait. If the quality of the bait is low and the quantity is insufficient, it is found that maggots fight due to hunger. The artificial mixed bait (weight ratio) may be: fish meal 20, blood meal 5, wheat flour 25, corn flour 20, bean meal 30.
