Problems solved by technology

The growth rate of individuals is affected by the breeding environment, and it is difficult for the selected individuals to be suitable for other breeding environments. The growth rate is faster and the stress resistance is better in the pond breeding environment, but the growth rate in other breeding environments is not necessarily the same. Well, thus causing the selected offspring to adapt to the singleness of the environment

Embodiment

[0022] A kind of high-efficiency breeding method for carp suitable for different breeding modes of the present embodiment comprises the following steps:

[0023] (1) Establishment of pedigrees: Breeding groups based on the Jian carp introduced from the Freshwater Fishery Research Center of the Chinese Academy of Fishery Sciences. In May 2012, 60 male Jian carp and 60 female Jian carp were selected for 1 male mating 1 female pair breeding, establish 60 first-generation selective breeding families;

[0024] (2) The fish of 60 first-generation selective breeding families are isolated and hatched in 60 net cages, and the fry of different families are isolated in different net cages for early cultivation. The first 2-5 days after hatching Feed with egg yolks made into pulp through a 150-mesh net, and sprinkle twice a day; use soybean milk, sprinkle three times a day on the 5th-12th day, and fish out rotifers in the water every 2 days for feeding; 13-25th day. Every day, feed the c...

Abstract

The embodiment of the invention discloses a high-efficiency carp breeding method suitable for different aquaculture modes. According to the high-efficiency carp breeding method disclosed by the invention, characters including body weights and body types which have more important effects on body quality are utilized in an emphasis mode under the different aquaculture modes, breeding fish is markedand bred in the different aquaculture modes, and then data are collected. Thus, varieties suitable for different aquaculture modes are bred out, single applicability of the chosen fish to the aquaculture environment is overcome, and the improved variety breeding efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of genetic breeding of aquatic animals, in particular to a high-efficiency carp breeding method suitable for different breeding modes. Background technique [0002] Carp is a traditional cultured fish in my country, and it is also the main freshwater cultured fish, which is suitable for farming in most areas of our country. The culture of carp has a long history, there are many breeds, and the breeding technology is mature, so it is difficult to increase the breeding output only through the breeding technology. Therefore, in order to further improve the yield and quality of carp, it is necessary to carry out genetic improvement on the currently farmed species. [0003] In breeding practice, body weight is an important economic indicator of breeding. Nowadays, BLUP multi-trait multi-breeding is generally used. After PIT marking of family fish, the pond is generally used for breeding in the same pond, and the...
