Problems solved by technology

However, different freshwater fish have different feeding requirements and have different nutritional requirements.
[0004] If you use corresponding specific feeds for different freshwater fish species during polyculture, it will increase the workload and cause waste, and the feed return rate will be low; moreover, when feeding specific feeds separately, the feed varieties and feed protein settings will be messy, Although it can provide the nutrients it needs, if the feed-energy-egg ratio is not appropriate, especially high-protein and low-energy feeds, it is easy to cause fish liver and gallbladder diseases and water eutrophication

Abstract

The invention relates to a mixed feed for mixed aquaculture of freshwater fishes. The mixed feed includes a basic material. The basic material includes fish meal, soybean meal, wheat, cottonseed meal, rapeseed meal and soybean oil, and also includes by weight: 1.5-2.2% of calcium phosphate, 1.5-2.2% of bentonite, 1.5-2.2% of zeolite powder, 0.1-0.25% of choline chloride, 0.1-0.25% of salt, 0.02-0.05% of compound probiotics, 0.04-0.08% of vitamin C, 0.005-0.02% of allicin, 1.0-2.0% of compound vitamins and 1.0-2.5% of compound mineral salts. The feed is suitable for intensive culture or polyculture of megalobrama amblycephala, black carp, grass carp, common carp and the like, so that the freshwater fish feed is generalized, the return rate of the feed is improved, the aquaculture water eutrophication and fish liver and gallbladder diseases are reduced, the output of unit aquatic products is raised, and the economic benefits of farmers are significantly improved.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a compound feed for freshwater fish mixed culture and fish culture. Background technique [0002] In the process of intensive farming of freshwater fish, the choice of feed is a very important factor. [0003] At present, since there are many species of freshwater fish cultured (grass carp, bream, herring, carp, etc.), intensive cultivation of a single species or polyculture of several species can increase the variety of products. However, different freshwater fish have different feeding requirements and different nutritional requirements. [0004] If you use corresponding specific feeds for different freshwater fish species during polyculture, it will increase the workload and cause waste, and the feed return rate will be low; moreover, when feeding specific feeds separately, the feed varieties and feed protein settings will be messy, Although it can provide the nutrients it ne...
