Scientific feeding is the key to improving fish feed utilization and aquaculture efficiency. In this paper, several methods for improving the utilization of bait are introduced in combination with work practices. First, made of granular food According to different breeds of various raw materials will be made according to a certain ratio of suitable pellet feed, food nutrition should be comprehensive, high protein content, stability in the water for longer, lighter to lose. Second, increase the number of feeds bait in the fish intestine residence time is short, fast growth season fish metabolism, low utilization of feed, therefore, in the case of the total amount of change, should reduce the number of each feeding, increase investment The number of baits, so that the fish is always in a state of starvation, improve the utilization of bait and reduce the bait coefficient. Third, adjust the water quality of water quality is good or bad, a direct impact on the effect of fish feeding, good water quality and high dissolved oxygen, especially in the state of dissolved oxygen in water is good, fast fish growth, high utilization of food. Water quality control measures include: (a) rational use of aerators; (b) regular splashing of lime water; (c) timely addition of fresh water. Fourth, pay attention to the spring and autumn feeding The water temperature in the five, six, and October must be stable at about 20 °C, this time is more suitable for fish growth temperature, lack of oxygen-free floating head hidden. Fifth, the fish stocking specifications and put the nutrient density should be appropriate to increase the number of rearing stocks, reducing the stocking weight, so that fish stocking specifications, density and feed amount to adapt to the total, in order to increase individual growth of fish species, and increase net production.
