Problems solved by technology

Due to the unique physiological characteristics of Dabry's sturgeon, the traditional methods of broodstock recovery and adult sturgeon feed can no longer fully meet their postpartum nutritional needs, and the gonads will slow down and stagnate again.

Abstract

The invention belongs to a fish feed, and in particular relates to an acipenser dabryanus postpartum parent fish feed. The acipenser dabryanus postpartum parent fish feed comprises fish meal, soybean protein concentrate, bean meal, flour, soybean oil, soyabean lecithin, fish oil, monocalcium phosphate, composite vitamin, composite mineral salts, yeast extract, astaxanthin, choline, betaine, a mildew preventive, immune polysaccharides, bentonite, dl-alpha-tocopherol acetate, ethoxyquin and vitamin C phosphate. The feed can meet a requirement of acipenser dabryanus postpartum parent fish on nutrition; the recovery time of parent fish is shortened, and gonad development is promoted, so that the fecundity of the parent fish is enhanced.

Description

technical field [0001] The invention belongs to a fish feed, in particular to a feed for parent fish of the dabry's sturgeon after giving birth. Background technique [0002] Dabry's sturgeon, commonly known as the Yangtze River sturgeon, belongs to the order Sturgeoniformes, the family Acipenseridae, and the genus Acipenserus. , has high academic value and ecological value. [0003] After breaking through the artificial reproduction technology of the Dabry's sturgeon, the mature eggs in the Dabry's sturgeon ovaries are usually emptied at one time, resulting in the exhaustion of the nutrients accumulated for many years in the Dabry's sturgeon, and the constitution is very weak, which affects the later gonad development and reproductive activities. . The recovery of broodstock after birth and the intensive cultivation of nutrients will make up for the adverse effects of the loss of nutrients in broodstock. Due to the unique physiological characteristics of Dabry's sturgeon...
