Problems solved by technology

[0002] In the current aquatic animal breeding program, the family content or group content used for performance measurement is generally within tens to one hundred individuals. The selection of this individual number can ensure that the cost of breeding and measurement can be saved under the premise of accurate estimation of breeding parameters , but since the performance measurement group is the selection group, it is difficult to keep the seed rate lower than 1% during the selection, which makes the high fecundity of aquatic animals not be effectively utilized and brought into play

Embodiment

[0026] Taking sea urchin as an example, follow these steps:

[0027] Construct 10 breeding families, and each family contains no less than 2000 individuals;

[0028] At the age of 6 months, randomly select 50 individuals from each breeding family, divide them into 10 performance measurement groups with the family as a unit, and carry out separate breeding to ensure that the breeding environment such as water temperature and bait of each family is consistent;

[0029] Select the 4 largest individuals from the remaining offspring of each breeding family as the seed population, and the selection rate is about or lower than 2‰. Divide the reserved seed individuals in each family into 10 groups of reserved seed groups and raise them separately, and ensure that the water temperature, bait and other breeding environments of each family are consistent;

Abstract

The invention discloses an aquatic animal breeding method aiming to solve the problem that seed reserving rate is low in conventional breeding methods. Families for seed reserving and performance testing are separated, related heritability coefficients rA are calculated according to results of performance testing, and selection of different seed selection methods is performed according to calculation results. By the method, seed reserving rate is lowered on the premise of not increasing cost, and selection response is improved greatly, so that the purpose of accelerating breeding progress is achieved. Therefore, the method has broad market and scientific research prospects.

Description

technical field [0001] The invention relates to a breeding method for aquatic animals, in particular to a breeding method for aquatic animals in which performance measurement and seed saving are separated. Background technique [0002] In the current aquatic animal breeding program, the family content or population content used for performance measurement is generally within tens to one hundred individuals. The selection of this individual number can ensure that the cost of breeding and measurement can be saved under the premise of accurate estimation of breeding parameters , but because the performance measurement group is the selection group, it is difficult to keep the seed rate lower than 1% during the selection, which makes the high fecundity of aquatic animals not be effectively utilized and brought into play. For general aquatic animals, a single parent can produce a large number of offspring. If the species can be selected from all the offspring, the seed retention r...
