Embodiment Construction

[0021] Build a fish pond of 1 mu to ensure its water demand and the water source without pollution. The fish pond includes an imitation ecological flow pool, hatching pond and cultivation pond; 200kg of quicklime is sprayed per mu for disinfection. It is at the same height as the water, and a filter screen is installed; new water is injected in 2-3 weeks, and the water quality is clean; the water temperature of the imitation ecological flow pool is 13-18°C, the flow rate is 0.01-0.03m / s, and the benthic diatoms are cultivated with 60-mesh sieve silk; Place enough clean brown chips, willow roots or aquatic plants as fish nests; the cultivation pool should have an area of ​​about 5 square meters, with a depth of 30-40cm and a flow rate of 0.03-0.05m / s to prevent the harm of snakes, frogs, rats and other animals ; Pay attention to daily inspection. Choose wild fish of uniform size, about 500g / tail; the stocking amount is 10,000 fish, and the ratio of male to female is about 2:1;...

Abstract

The invention relates to an artificial breeding technology for schizothorax grahami. The artificial breeding technology for the schizothorax grahami includes that cleaning and sterilizing a breeding pond; placing fish seeds; acclimatizing parent fishes and hastening parturition to spawn; incubating fish fries; feeding fodder; fishing and coming into the market. The artificial breeding technology for the schizothorax grahami is capable of effectively improving the problems of low survival rate, slow growth and low reproductive capacity of artificial schizothorax grahami breeding, improving the yield and economical benefit of the schizothorax grahami and promoting the development of the schizothorax grahami breeding industry.

Description

technical field [0001] The invention relates to a Kunming Schizothorax artificial breeding technology, in particular to a large amount of Kunming Schizothorax that can be rapidly cultured on a large scale, thereby improving economic benefits. Background technique [0002] Kunming Schizothorax is a small plant-eating cold-water fish with quick temper, strong jumping ability and strong stress response. The meat is tender, delicious, and has high nutritional value for muscles. It is a high-end edible fish. Its wild fish is difficult to domesticate, with low survival rate, late sexual maturity, low fecundity, slow growth, jumping, consumes a lot of body muscles, and affects yield and quality. How to domesticate and breed Kunming Schizothorax, effectively protect and expand its germplasm resources, and improve the scale and economic benefits of Kunming Schizothorax breeding have become the main direction of research. Contents of the invention [0003] The purpose of the presen...
