Abstract

The invention belongs to fish feed and particularly discloses feed of adult acipenser dabryanus. The feed is prepared from fish meal, soybean protein concentrate, soybean meal, flour, soybean oil, soyabean lecithin, fish oil, calcium biphosphate, a vitamin complex, complex mineral salts, choline, betaine, a mould inhibiter, immune polysaccharides, bentonite and ethoxyquin. The feed provided by the invention can meet the requirement on nutrients of adult acipenser dabryanus, and can be used for enhancing the growth rate of the adult acipenser dabryanus and lowering the death rate of the adult acipenser dabryanus.

Description

technical field [0001] The invention belongs to a fish feed, in particular to a feed for Dabry's sturgeon adult fish. Background technique [0002] Dabry's sturgeon, commonly known as the Yangtze River sturgeon, belongs to the order Acipenseriformes, Acipenseridae, and the genus Acipenserus. , has high academic value and ecological value. In recent years, as the country has stepped up efforts to protect the ecological environment, research has been gradually carried out on the enhancement and breeding of rare and unique fish in the upper reaches of the Yangtze River, biodiversity protection and sustainable development of fish resources. However, limited by the amount of resources, there are few studies on Acipenser dabryi at present, and only studies on morphological structure, digestive system, pond culture, taxonomic status, etc. have not been seen at home and abroad on the nutritional formula of adult Acipenser dabryi. . The conventional fish feed currently used is not...
