Individual marking method applied in echinoderm breeding process achieved through BLUP method

The invention provides an individual marking method. According to the method, the problem that in traditional breeding, echinoderms are difficult to mark is solved, individual marking can be conveniently performed on the echinoderms such as sea cucumbers and sea urchins, the characters such as individual feed coefficients which cannot be recorded through traditional fluorescent marking can be also recorded besides that the individual growth characters can be monitored, and compared with traditional fluorescent marking, the method has the advantages that the cost is lower, and selected individuals can be more easily identified in young echinoderm selecting. Due to the method, the possibility of breeding the echinoderms through the BLUP method is achieved. Accordingly, the method has multiple advantages and is particularly suitable for being applied and popularized in the breeding field and very wide in market prospect.
