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.

The invention discloses a fry culture cultivating method for schizothorax prenanti. After a fish pond is disinfected, fish fry disinfected with a povidone-iodine solution are put in the pond, micro-flow water is adopted for cultivation, cooked egg yolk is thrown and fed to the fry for several days, plankton bait is thrown and fed to the fry after 5-7 days, cut water earthworms and broken juvenile schizothorax prenanti materials are thrown and fed to the fry after 20 days, and juvenile schizothorax prenanti feed is thrown and fed to the fry till the fry reach the specification of larva fish. The schizothorax prenanti fish fry cultivated through the method are low in cost, high in survival rate and quick in growth, the cooked egg yolk, the rotifer and cladocera plankton bait, and the water earthworms and the juvenile schizothorax prenanti feed are thrown and fed to the fry in a staged mode, and therefore the high growth rate can be kept at each stage.
