Problems solved by technology

However, the phosphorus content in the formula is high. Due to the low utilization efficiency of feed phosphorus by sea bass, the phosphorus in the feed that cannot be absorbed and utilized by fish will be discharged into the aquaculture water body, which brings potential risks to high-density aquaculture water bodies.

Abstract

The invention discloses weever feed with a low-phosphorus formula. The weever feed is mainly prepared from fish meal, bean pulp, peanut meal, cottonseed meal, rapeseed meal, complex enzyme, phytase, high gluten flour, fish oil, soybean oil, choline chloride, soybean phosphatide oil, vitamin C phosphate, monocalcium phosphate, zeolite powder, vitamin premix, mineral substance premix and sodium alginate. After the low-phosphorus weever feed disclosed by the invention is used, the reduction amplitude of the coefficient of food for breeding weever is large, is 0.93-1.10 and is reduced by 12.70 to 26.19 percent compared with that of commercial feed; the apparent digestibility of phosphorus in the feed is improved by 14.14 to 20.68 percent, the content of total phosphorus in a water body is reduced by 12.93 to 16.44 percent, and the utilization efficiency of phosphorus is improved by 14.14 to 20.68 percent.

Description

technical field [0001] The invention relates to a perch feed with low phosphorus formula. Background technique [0002] Perch is the main species of marine aquaculture in my country due to its fast growth, delicious taste and high economic benefits. At present, in the main ponds where sea bass are raised, artificial feeds are generally used to obtain high yields, but the phosphorus content of commercial sea bass feeds on the market is generally high. Randomly selected 17 perch feeds produced by different manufacturers of 8 brands at different stages, and found that the average value of total phosphorus content was 2.10%, the maximum value was 2.86%, and the minimum value was 1.69%. For optimal growth, juvenile perch require 0.9% total dietary phosphorus and 0.68% available phosphorus (Zhang et al, 2005). Phosphorus sources are mainly fishmeal, plant raw materials and inorganic phosphorus (adding mineral salts). The utilization rate of phosphorus in fishmeal is low, and pla...
