Parent-tor-brevifilis gonad synchronous and early development method

Abstract

The invention discloses a parent-tor-brevifilis gonad synchronous and early development method. The parent-tor-brevifilis gonad synchronous and early development method includes the following steps: A, selecting an aquaculture fish tank; B, selecting parent tor brevifilises; C, carrying out temporary breeding, wherein the parent tor brevifilises are immersed by a salt solution with the mass fraction ranging from 3wt% to 5wt% for 5 minutes to 10 minutes, then the parent tor brevifilises are placed in a circulating water system to be temporarily bred for 1 week, and the weight of artificial particle feed fed every day is 3% to 5% of the weight of the parent tor brevifilises; D, breeding the parent tor brevifilises, wherein the parent tor brevifilises are placed into the aquaculture fish tank with the female-to-male ratio 1:1.2, the temperature of water in the aquaculture fish tank rises to 22 DEG C, the illumination intensity of the aquaculture fish tank ranges from 390 lux to 410 lux, the sunlight application time of the aquaculture fish tank is set to be 18 h, a surfing pump and a filtering system run all the time, micro water flow stimulation is formed, and after the water is changed each time, microbial preparations need to be added to be used for adjusting the water quality. By means of the parent-tor-brevifilis gonad synchronous and early development method, the female parent tor brevifilises and the male parent tor brevifilises can be promoted to be developed synchronously; in addition, the gonads of the female parent tor brevifilises and the male parent tor brevifilises can be developed early, and the parent tor brevifilises with the synchronously-and-fully-developed gonads can be obtained only in three months.

Description

technical field

[0001] The invention relates to the technical field of promoting fish development, in particular to a method for the synchronous and early development of gonads of broodstock fishes. Background technique

[0002] The genus Osteophyta belongs to the class Osteophyta, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, genus Osteophyta, subgenus Osteophyta. Commonly known as: Hasi, Chongkou, Mazui, Laju. The valvefish is a middle-lower fish that lives in clear running water. It has a streamlined body shape, a pointed head, and strong fins. It is one of the fishes that are good at swimming. It often passes through the rocks at the bottom of the water, sucks food from the bottom of the river and the stone surface with its trumpet-shaped flexible mouth, and feeds on benthic molluscs, aquatic insects and their larvae, plant fragments and filamentous algae. Generally, 3-year-old fish reach sexual maturity, and the spawning period is estimated to be between June and July...
