Artificial feed domestication method for hybrid siniperca chuatsi

Abstract

The invention discloses an artificial feed domestication method for hybrid siniperca chuatsi. The method comprises the following steps of screening out a new hybrid siniperca chuatsi strain which grows fast and is easy to domesticate; hybridizing parent fish of the screened new hybrid siniperca chuatsi strain, and performing artificia propagating to obtain hybridized siniperca chuatsi F1 fry; andstep 3, carrying out full-artificial feed domestication on the obtained hybrid siniperca chuatsi F1 fry easy to domesticate, and keeping the water temperature in a cement pond to be 26 + / -0.5 DEG C, the illumination intensity to be 50lx and the culture density to be 200 / m<3> in the domestication management process. According to the method, the new hybrid siniperca chuatsi strain easy to domesticate is bred, the matched artificial feed domestication method for the hybrid siniperca chuatsi is provided, sufficient artificial feed is provided for the siniperca chuatsi industry to breed the siniperca chuatsi fry, and the current situation that the siniperca chuatsi industry is lack of the fry easy to domesticate is changed. The artificial feed domestication method for the hybrid siniperca chuatsi provides optimal environmental factors beneficial to growth and domestication of the new hybrid siniperca chuatsi strain. Siniperca chuatsi artificial compound feed is optimized and developed according to the nutritional requirements in the domestication period, in particular to the matched use of additives and phagostimulants.

Description

technical field [0001] The invention relates to the technical field of special aquaculture, in particular to a method for taming artificial feed for hybrid mandarin fish. Background technique [0002] Mandarin fish has always been a rare freshwater fish in the tip of the tongue culture in my country. Commonly known mandarin fish mainly refers to Siniperca chuatsi, which has tender meat, delicious taste, few intermuscular thorns, rich nutrition, and has the effect of nourishing qi and blood, and benefiting the spleen and stomach, so it is eaten as high-quality fresh water with high economic value. Fish is very popular with modern consumers. [0003] However, mandarin fish is a kind of ferocious fish that eats fish all its life from the opening of the mouth. Generally, the bait coefficient of mandarin fish grown with live fish bait is 4-5:1, so each mu of mandarin fish breeding pond needs to be equipped with at least 4-5. 5 acres of live bait fish production pond. For a lon...

AI Technical Summary

Problems solved by technology

Among the 3 genera and 8 species of mandarin fish, Siniperca chinense has the fastest growth rate and the largest body size, and is currently the main cultured species of mandarin fish in my country, but its artificial diet is difficult to domesticate and the effect is unstable; ) is more tame, but it grows slowly and is small in size

At present, no key breakthrough has been made in the technology of raising mandarin fish with artificial feed. To solve this problem, on the one hand, it is necessary to screen and breed mandarin fish strains with high tameability; Mandarin fish artificial diet with good palatability and food attraction

Traditional pond mandarin fish farming is restricted by factors such as live bait fish resources, breeding area, and high-quality seedlings. The whole process of mandarin fish farming on artificial feed is the fundamental way to solve the problem of small farming scale, low resource utilization rate and meet market supply.
