Method for utilizing perfectly straight club mosses to hatch carp fries

Abstract

The invention discloses a method for utilizing perfectly straight club mosses to hatch carp fries. By fully utilizing the characteristics of the club mosses, naturally diffused fragrance of the club mosses can stimulate female fish to perform ovulation, and generally the female fish can perform spawning on the next day after being put, while the time is delayed for 2-3 days by using other roe attachments. In addition, the club mosses are erected into a club moss layer similar to a net, accordingly the roe attachment rate can be improved, the attachment rate can be improved by 20-30% or even can be higher by utilizing the club mosses compared with the attachment rate obtained by using other attachments, and further the roe hatching success rate is improved.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a method for hatching carp fry by using straight stone pine. Background technique [0002] Commonly known as carp guaizi, Maozi, etc., carp belongs to Cyprinidae. The side of the body is flat and the abdomen is round, the mouth is horseshoe-shaped, and there are 2 pairs of whiskers. The base of the dorsal fin is longer, and both the dorsal and anal fins have a thick and serrated spine. Body side golden yellow, caudal fin lower lobe orange red. Carp usually inhabit the bottom of water bodies overgrown with aquatic plants in rivers, lakes, reservoirs, and ponds, and mainly feed on benthic animals. It has strong adaptability, cold resistance, alkali resistance and hypoxia resistance. It can lay eggs in running water or still water, and the spawning places are mostly in aquatic plants, and the eggs adhere to the aquatic plants to develop. Carp is one of the freshwater fishes w...

Problems solved by technology

[0003] At present, carp is the main object of freshwater aquaculture, and its breeding season is from April to June. For the field of carp breeding technology, in addition to artificial insemination and hybridization, the most traditional technology is to put the male and female bodies of carp in a certain proportion. In a culture pond, and then use it as the parent fish, make the carp parent breed freely lay eggs in the culture pond, and then freely hatch into the method for raising seedlings, although this method can reduce the cost of raising seedlings than artificial insemination and hybridization technology, and improve the efficiency of raising seedlings. Natural adaptability, however, its survival rate is low, which affects the profit of seedling cultivation, making the survival rate of fish eggs affected by uncontrollable factors, resulting in a low survival rate of fish eggs
