Embodiment Construction

[0022] The present invention will be further described below with embodiment.

[0023] The crossbreeding method of cocked mandarin fish and spotted mandarin fish comprises the following steps:

[0024] 1. Breeding of broodstock

[0025] The broodstock used in this embodiment was collected in the autumn of the year before the breeding. The female parent of the mandarin fish is from the artificial culture pond, 2 years old, with a body weight of 1.0~1.3Kg / tail, and the male parent of the mandarin fish is taken from the wild population of the reservoir, and the age of the fish is 2 years old. , Weight 0.5 ~ 0.8Kg / tail. The brood fish of Siniperca sinensis and Siniperca mandarinus are placed in 4×3×2m respectively 3 During the cultivation period, the mandarin fish is fed with palatable small crucian carp, and the spotted mandarin fish is fed with palatable small crucian carp or fish pieces. From February 1st to April 15th of the breeding year, the water was flushed with a mic...

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...
