Schizothorax prenanti parent fish feed

Abstract

The invention discloses schizothorax prenanti parent fish feed. The feed is composed of, by mass, 15-20 parts of fish meal, 10-30 parts of bean pulp, 5-15 parts of dephenolized cottonseed, 10-20 parts of rapeseed, 10-30 parts of high protein flour, 5-8 parts of corn gluten meal and 5-10 parts of husk, perisperm and aleurone mixture as main materials, and appropriate amounts of soybean phosphatide oil, soybean oil, fish oil, vitamin premix, mineral premix, beta-glucan, vitamin C acetate, monocalcium phosphate, liver-protecting and gallbladder-benefiting element, mildew preventive, high-temperature-resistant phytase, choline chloride, vitamin and Chinese herbal medicine additive as auxiliary materials so that nutrition can be balanced. The feed is rich and balanced in nutrition and can improve the disease resistance and reproductive capacity of schizothorax prenanti parent fish.

Description

technical field [0001] Embodiments of the present invention relate to fish breeding industry, and more specifically, embodiments of the present invention relate to a broodstock feed for Schizothorax chinensis. Background technique [0002] Qikou Schizothorax is also called Yayu, Qikou, thin soft-shelled turtle, and Qikou fine scale fish. It is a cold-water fish and a bottom fish. It requires a lower water temperature environment. It likes to live at the junction of fast and slow currents. They mostly live in slow-flowing ponds. During the feeding season, they move around in an environment where the substrate is sand and gravel and the water flow is turbulent. There is a phenomenon of short-distance reproductive migration. Females need to reach sexual maturity at 4 years old, and males generally reach sexual maturity at 3 years old. . Schizothorax is distributed in the Minjiang River, Dadu River and other water systems. It is an important edible fish in the upper reaches of ...

Problems solved by technology

Although there have been some reports on the culture of Schizothorax, there are few techniques specifically for the artificial culture of Schizothorax

[0003] The Chinese patent applications whose publication numbers are CN102484983A and CN200410022179.7 respectively disclose methods for the artificial propagation of Schizothorax, mainly disclosing the cultivation conditions in the stages of insemination, hatching, and seedling cultivation, such as temperature, time, and environmental requirements. The bait for broodstock is only biological bait or cold-water fish feed of commercially available brands. Although this type of bait can provide considerable nutrients, the nutrition is not comprehensive, and it cannot improve its immunity and anti-oxidation emergency response capacity according to the special needs of broodstock. The reproductive ability of broodstock needs to be improved
