Abstract

The invention discloses a tor-brevifilis indoor cement pond net cage incubation method. The tor-brevifilis indoor cement pond net cage incubation method includes the following steps: A, repairing and maintaining an incubation pond, wherein a water inlet pipe and a strip-shaped micro-hole pipe oxygenation device are arranged at the bottom of the incubation pond, a potassium permanganate solution is scattered to the whole pond for disinfection, and then purified pond water filtered through yarn silk with the number of meshes ranging from 120 to 125 is injected into the pond to be aerated for use; B, arranging net cages; C, carrying out incubation, wherein after the water injected into the incubation pond is aerated for one week, gauze containing eggs is hung on iron wires at the tops of the net cages at intervals, oxygen dissolved in a water body in the incubation pond ranges from 5 mg / L to 10 mg / L, and the temperature of the water in the incubation pond ranges from 24 DEG C to 27 DEG C; D, preventing and treating tor-brevifilis diseases, wherein in the incubation process, nystatin dehydrate is thrown into the incubation pond every 10 hours to 14 hours to be used for preventing and controlling saprolegniasis, and if it is found that saprolegniasis exists in the incubation pond, methylene blue is scattered to the whole pond according to the amount of 2 g to 4 g per cubic meter. The tor-brevifilis indoor cement pond net cage incubation method is high in survival rate and high in incubation rate, and the incubation rate can be 88%.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for hatching clamfish in an indoor cement pond net cage. 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. Mature broodstock are required...
