Feed for improving reproductive capacity of parent fish of groupers

Abstract

The invention relates to the field of aquatic product fry culture feeds, and provides a feed for improving the reproductive capacity of parent fish of groupers. The feed is characterized by consisting of the following raw materials in parts by weight: 35-40 parts of fish meal, 5-7 parts of soybean protein concentrate, 12-17 parts of krill powder, 15-18 parts of flour, 1-3 parts of soybean lecithin, 2-4 parts of fish oil, 0.5-1.2 parts of calcium dihydrogen phosphate, 0.1--0.3 part of dl-alpha-tocopheiyl acetate, 0.3-0.5 part of complex vitamins, 0.5-1.0 part of complex mineral salt, 0.2-0.4 part of choline, 0.3-0.6 part of inositol, 0.01-0.05 part of ethoxyquin, 0.1-0.2 part of a mildewproof agent, 0.1-0.3 part of immune polysaccharide, 0.1-0.3 part of vitamin C phosphate ester, 6-8 parts of wheat bran and 4-6 parts of bentonite. The feed for improving the reproductive capacity of parent fish of groupers, provided by the invention meets nutrient requirements of the parent fish of groupers, promotes the gonadal development of the parent fish, and increases the survival rate of fingerlings.

Description

technical field [0001] The invention relates to the field of aquatic seedling feed, in particular to a feed for promoting the reproduction ability of grouper broodstock. Background technique [0002] Grouper, belonging to the order Perciformes, is a large and medium-sized marine fish in warm water. Grouper is rich in nutrition, and the meat is tender and white, similar to chicken, and is known as "sea chicken". Grouper is a low-fat, high-protein high-quality edible fish, and it is one of the species with high economic value in aquaculture. However, for a long time, the seedlings required for grouper farming have mainly relied on natural harvesting. In recent years, the amount of wild grouper resources has declined rapidly, and the scale of farming has been greatly restricted. The survival rate of the breeding fry of grouper is relatively low at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a feed th...
