Abstract

The invention relates to the technical field of feed production, and particularly discloses a parent fish feed for improving reproductive performance of parent micropterus salmoides. The parent fish feed comprises the following components in parts by weight: 50-60 parts of fish meal, 20-30 parts of chicken meal, 12-16 parts of rape seed cakes, 8-10 parts of soybean meal, 8-10 parts of refined paste, 5-8 parts of soybean protein concentrate, 3-6 parts of fish oil, 2-4 parts of chitosan, 1-2 parts of vitamin C, 1-2 parts of vitamin E and 1-2 parts of a trace metal additive. According to the parent fish feed disclosed by the invention, the refined paste exists in gaps of feed particles, so that the defect that the existing parent fish feed quickly dissolves in water and cannot be fully utilized can be effectively prevented. In addition, the soybean protein concentrate, the fish oil, the chitosan and the vitamin C in the formula can improve the reproductive performance of the micropterus salmoides parent fish, and the micropterus salmoides breeding feed has an excellent effect when being used for feeding micropterus salmoides.

Description

technical field [0001] The invention relates to the technical field of feed production, and specifically discloses a broodstock feed for improving the reproductive performance of California perch broodstock. Background technique [0002] Sea bass, formerly known as largemouth bass, is covered with grayish-white or light-yellow fine scales all over the body, but the color of the back line is darker, often greenish blue or light black, and there are often black markings along the side line, and the abdomen is gray-white. It is a rare carnivorous fish with strong disease resistance, rapid growth, easy catch and wide temperature adaptability. Due to the degradation of California perch germplasm resources, the quality of California perch species has been seriously affected, and the survival rate, disease resistance and adaptability to the environment of perch species have been greatly reduced, resulting in slow growth, many diseases, long breeding cycles, and poor bait.
