Curled-lip mandarin fish and spot and spotted mandarin fish hybridizing propagation process

Abstract

The curled-lip mandarin fish and spotted mandarin fish hybridizing propagation process includes the following steps: 1. reinforced culturing curled-lip mandarin fish as female parent fish and spotted mandarin fish as male parent fish; 2. injecting exogenous hormone to promote mature and induce spawning, flowing water stimulating to promote spawning, artificial dry insemination and managing during hatching, so as to reach spawning rate over 80 %, fertility rate up to 83.5 % and hatching rate up to 89 %; and 3. staged culturing of the hybrid mandarin fish and feeding habit conversion from live fish to non-live feed, so as to reach survival rate of hybrid mandarin fish fry up to 60 %. The hybrid mandarin fish has good taste, high disease resistance, high growth speed and capacity of ingesting non-live fish feed.

Description

technical field

[0001] The invention belongs to the technical field of fish breeding, and in particular relates to a hybrid breeding method of mandarin mandarin fish and mandarin mandarin fish. Background technique

[0002] Siniperca chuatsi and Siniperca scherzeri belong to the order Perciformes. The family, Siniperca genus, are all high-grade freshwater aquatic species. Since the early 1990s, the cultivation of mandarin fish has been widely carried out all over the country, and good economic and social benefits have been achieved. However, the mandarin mandarin fish needs to feed on live fish for life, and live fish of different sizes need to be fed in different growth stages. This special food habit of mandarin fish not only increases the cost and difficulty of breeding, but also affects the scale promotion of artificial breeding. In the mid-1990s, many domestic scientific research and production departments conducted a large number of studies o...
