Problems solved by technology

However, for species such as sea cucumbers and sea urchins, the BLUP method is difficult to apply to breeding practice, because sea cucumbers, sea urchins and other species cannot achieve easy-to-read individual markers (fluorescent markers, etc.) that are implemented on species such as bony fishes and crustaceans. This makes the estimated breeding value unable to be used as the selection basis for the selection operation

Embodiment Construction

[0020] The specific embodiments of the present invention will be described below in conjunction with the drawings. Such as figure 1 Shown:

[0021] An individual marking method in the breeding process of echinoderms BLUP method, according to the following steps:

[0022] When the body weight of sea urchins in the breeding population reached more than 0.1g, 50 sea urchins of 50 families were randomly sampled, and the number of each sample was 50.

[0023] On an individual basis, each family of sea urchins was placed in a plastic breeding net bag with a size of 15cm×20cm and a mesh size of 1mm.

[0024] Place a 1.5ml centrifuge tube in the mesh bag, and place a piece of sulfuric acid paper in the tube. Use a pencil to record the family number and individual number of the individuals in the mesh bag on the paper. Plastic signs are placed outside the mesh bag, and a marker is used to record on the signs. The family number and individual number of the individual in the net bag.

Abstract

The individual marking method of the present invention solves the problem that it is difficult to mark echinoderms in traditional breeding, and can conveniently make individual marks on echinoderms such as sea cucumbers and sea urchins. In addition to monitoring the growth traits of individuals, it can also record Traits that cannot be recorded using traditional fluorescent markers, such as the bait coefficient of individuals, are also cheaper than traditional fluorescent markers, and it is easier to identify selected individuals during seed selection. The emergence of this method makes it possible to breed echinoderms using the BLUP method. Therefore it can be said that it has possessed multiple advantages, and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

Description

Technical field [0001] The invention relates to a marking method, in particular to an individual marking method in the breeding process of echinoderms BLUP method. Background technique [0002] BLUP is the best linear unbiased prediction (Best Linear Unbiased Prediction). It is the most widely used method for estimating the value of a sports species in animal and plant selection breeding. It can significantly improve the accuracy of the estimation of the value of a sports species, thereby significantly improving genetic progress. . Since the 1970s, the BLUP method has been widely used in selective breeding of livestock and poultry, and in recent years has become a conventional method of selective breeding of livestock and poultry. Although the selection and breeding of aquatic animals has been carried out late, the BLUP method has been used in aquatic animals such as Atlantic salmon, tilapia and other bony fishes and crustaceans such as Penaeus vannamei and Penaeus monodon over ...
