But the field that the feed that this invention records involves is seawater fish feed, there is very big difference in the living environment of seawater fish and freshwater fish, mainly manifests as the difference in salinity, so the physiological metabolism and nutritional requirements of fish living in different environments are different. There is a huge difference, the seawater fish feed is not suitable for the cultivation of freshwater fish in circulating water

Abstract
The invention relates to feed for freshwater fish fries bred in circulating water and a preparation method and a use method thereof and belongs to the technical field of fish feed. The feed provided by the invention comprises the following raw materials in parts by weight: 2-3.5 parts of spirulina powder, 3-6 parts of schizochytrium microalga powder, 15-18 parts of sardine meal, 5-8 parts of mackerel meal, 6-9 parts of yolk powder, 8-11 parts of whole milk powder, 20-23 parts of soybean meal, 2-5 parts of chicken intestine powder, 0.5-2 parts of refined fish oil, 0.5-2 parts of soybean oil, 2.7-4.6 parts of corn flour, 14-16 parts of alpha-starch, 1.5-3 parts of calcium dihydrogen phosphate, 0.5-2 parts of a vitamin premix, 1.5-3 parts of a trace element premix, 0.2-0.4 part of a special microecological preparation and 0.4-0.7 part of a functional preparation. The special compound feed provided by the invention is capable of effectively enhancing the immunity of freshwater fish fries bred in circulating water, improves the survival rate of the freshwater fish fries, is likely to form well-shaped excrement, is favorable for breeding management in a circulating water system, ensuresthe nutritional requirements of the freshwater fish fries, in a growth period, bred in circulating water and promotes healthy growth of the freshwater fish fries.
Description
technical field [0001] The present invention relates to a circulating water aquaculture freshwater fish fry feed and its preparation method and use method. More specifically, the present invention relates to a feed that can effectively enhance the immunity of freshwater fish larvae in circulating aquaculture and improve the survival rate of freshwater fish fry. The feed for circulating aquaculture freshwater fish fry and its preparation method and use method belong to the technical field of fish feed. Background technique [0002] Aquaculture has been small-scale and decentralized, and gradually tends to large-scale, industrialized production, and intensive management. This traditional labor-intensive industry is gradually developing into a capital- and technology-intensive industry. Through the vigorous introduction of biotechnology and information technology , control technology, logistics technology and other latest technological achievements have improved the technical l...
