Problems solved by technology

[0006] However, in the current breeding process, most of the hard pellet feeds made by ordinary pellet mills have poor stability in water, large feed waste, and serious impact on water quality. At the same time, due to the hard pellets and the addition of binders, etc. up
[0007] The digestibility of feed in aquaculture is reduced, which affects the breeding effect of feed

Abstract

The invention discloses an aquaculture feed, prepared from, by weight, 12-20% of soybean, 8-18% of wheat bran, 8-18% of fish meal, 25-30% of defatted bran, 5-15% of meat and bone meal, 25-30% of rapeseed meal, 25-30% of cassava starch, 2-8% of malt sprout, 0.5-1% of plant oil, 0.5-1% of soybean oil, and 0.5-1% of trace elements. The aquaculture feed of the invention has high nutritional level and rarely contaminates cultivation water.

Description

technical field [0001] The invention relates to a feed for fish, in particular to a feed for aquaculture. Background technique [0002] Warm-water pelagic fishes are large in size and generally do not form large groups. They swim from the open sea to the offshore in spring and summer, and return to the sea in winter. [0003] Swim to the deep waters of the open sea. Larger individuals are 5 kg to 10 kg. Aquaculture meat is tender and delicious. It is a valuable edible fish, but the yield is not enough, so it can be used as a seawater feeding object. There are a certain number of fish fry in Guangdong, Guangxi, and Fujian, and artificial seedlings have been successfully raised in Taiwan and Hainan. [0004] Under artificial feeding conditions, after feeding for a short period of time, if they are fed with their favorite food, they will still fight fiercely. [0005] grab. The growth rate of aquaculture is very fast, and the weight of feeding for half a year can reach abo...
