Shellfish pedigree breeding marking contrast method

Abstract

The invention relates to the technical field of aquatic organism selective breeding marking, and relates to a marking contrast method of an offshore intermediate breeding and development stage during a shellfish pedigree breeding process. The invention specifically relates to a shellfish pedigree breeding marking contrast method. According to the method, an environment-friendly plastic pad is adopted as a material for a geometric-shaped marker; different geometric holes are formed in the marker by cutting; and marking can be realized with the holes and the color of the marker. According to the method, the cost is low, and the marking is simple and clear. The marker can be accurately identified under a situation of foreign body adhesion. The recognition degree is high, and the marker meets production needs. The marker is convenient to manufacture, and is easy to carry. The marker can be widely and repeatedly applied. The marker has long preservation time and high preservation rate. Marking is carried out by tying the marker on a cultivation cage with a plastic tie, such that physiological damage to the shellfish is prevented, and the marker is stable and is prevented from falling and loss. Therefore, the stability of the marker is high. A marking rate and readable rate of the marker are both 100%, such that shellfish pedigree breeding large-scale industrialization development requirements are met. The method has an important significance in shellfish industry breeding.

Description

technical field [0001] The invention belongs to the technical field of markers for selective breeding of aquatic organisms, and relates to a marker control method for intermediate breeding and growth stages at sea in the shellfish family breeding process, in particular to a marker control method for shellfish family breeding. Background technique [0002] Selective breeding is an effective method for breeding new varieties and has achieved widespread success in animal and plant breeding. Among them, the establishment of family lines and systematic breeding are important means of selective breeding. At present, there have been many reports on systematic (family) breeding at home and abroad. Excellent families can be screened generation by generation, purified within the family and crossed between families, to fix the additive genes of economic traits in the population, increase the frequency of genes with economic value in the population, and finally obtain new varieties tha...

Problems solved by technology

At present, the more common family marking techniques mainly include cut appendages in crustaceans, tattoos, deep tissue vital staining, line marking, fluorescent pigment marking, fluorescent plate marking, eye marking, branding, etc.; fish include fin clipping, Marking types such as chip and closed-loop plastic label marking; as the aquaculture industry with the highest output in my country, the shellfish industry has continuously expanded its breeding scale. The whole in vitro culture net cage is marked by OEM, branded, scratched or marked with a marker pen. However, during the culture process, especially in the process of mariculture in sea areas, the markers are easy to fall off and lost, and the marks on the markers are in the seawater. It is easy to be blurred under washing, difficult to identify under the condition of fouling organisms, and the recognition and readability are low, which directly affects the results of shellfish family breeding

At present, no marking method suitable for large-scale breeding has been found, which is more convenient, fast, highly recognizable and readable
