Abstract

The invention discloses an individual labeling method for selective breeding of tilapia. Firstly, an appropriate plastic pin, a tagging gun, a closed loop plastic tag and so on, are selected; secondly, Tricaine methane sulphonate with a concentration of 0.33g / L is used to anesthetize the tilapia; and then a fish body is labeled. The tilapia is kept a posture of swimming during the labeling and faces toward the left side; an insertion point is positioned at the front end on the back of the fish body; the closed loop plastic tag is sleeved on a gun needle; the plastic pin directly passes through the fish body to fix a label, and the length of the plastic pin exposed outside the fish body is between 2 and 4cm; and finally the labeled tilapia is placed into a 10 percent povidone iodine solution for soaking disinfection. The method has the advantages of simple operation, low cost, and high automation, has less damage degree to the fish body, ensures that the retention rate of the label is more than 90 percent and the effective recognition rate is more than 90 percent, can not affect the normal activity of the tilapia, and can meet the need of large-scale labeling of selective breeding of the tilapia.

Description

Technical field:

[0001] The invention belongs to the fish individual marking technology in the field of aquaculture, and is a technical method for realizing identification of a large number of fish and detecting each fish in tilapia breeding. Background technique:

[0002] At present, in the selective breeding of tilapia, the population source, parental parent, pedigree, production performance, and fish factory and sales destination of each fish can be traced through markers. At the same time, when testing related to economic traits, It is necessary to test tilapia larvae from different sources in the same environment until they grow up in the same breeding environment in order to improve the accuracy of genetic parameter estimation. Zhang Tanglin, Institute of Hydrobiology, Chinese Academy of Sciences, etc. in the research progress of fish marking technology ("China Aquatic Science", 2003, No. 3, Volume 6, 246-253), proposed that it began in the 1920s. Cut off the fin mark...
