Embodiment Construction

[0017] Describe technical content of the present invention in detail below by embodiment.

[0018] Different levels of vitamin A were added to the basal diet of turbot female broodstock, and different levels of vitamin E were added to the basal feed of male broodstock. Prepared from mixed materials and other raw materials. See Table 1 for the feed composition and nutrient composition analysis of the female fish experiment. 0 (control), 10,000 IU / kg (10,000 groups) and 80,000 IU / kg (80,000 groups) vitamin A were added to the basic feed respectively; The composition and nutrient composition analysis are shown in Table 2. 0 (control group), 200 mg / kg (E200 group) and 700 mg / kg (E700 group) vitamin E were added to the basal feed respectively. Reserve at 18°C.

Abstract

The invention discloses a method for improving the quality of turbot sperm eggs and larval and juvenile, belonging to the field of nutrition and feed of aquatic livestock. Vitamin A is added into a female turbot patent fish feed until the final content is 19000IU / kg, and vitamin E is added into a male patent fish feed until the final content is 244-721mg / kg. The vitamin A can improve the egg laying amount of turbot patent fish and improve the quality of eggs, the activity of SOD (Superoxide Dismutate) in the blood serum of patent fish is improved obviously, MDA (Malondialdehyde) is obviously reduced, and the antioxidation capacity of patient fish mechanism can be improved; and the vitamin E can obviously improve the testis index, sperm generating amount, service life of sperm, sperm density and sperm mitochondria number of male fish, and improve the quality of the sperm of patient fish of turbot. As the female patent fish feed and the male patent fish feed are fortified respectively, the floating rate, the fertility rate and the hatching rate of fertilized ova as well as the survival rate and the length of larval and juvenile hatched primarily can be improved obviously.

Description

Technical field: [0001] The invention belongs to the field of aquatic animal nutrition and feed, and in particular relates to a method for improving the quality of turbot sperm eggs and larvae. Background technique: [0002] In recent years, with the rapid development of the aquaculture industry, people's demand for high-quality seed has increased greatly. In order to obtain a large number of high-quality seed, the cultivation of broodstock is particularly important. Previous studies have shown that the nutritional status of broodstock directly affects the yield and quality of their sperm and eggs, and affects the production efficiency of seedlings. Animal reproduction period is a special physiological period, and its demand for nutrients is different from other periods. Some nutrients, such as essential fatty acids and antioxidant substances, are particularly important for broodstock nutrition. The demand in the breeding period is greater than that in the growth period, but...
