Cultivation method of sturgeon

Abstract

The invention discloses a cultivation method of sturgeon. The method comprises the steps as follows: firstly, a cement culture pond is sterilized for accommodating sturgeon fry; the sturgeon fry is put into the culture pond, and greenhouse cultivation of the sturgeon fry is performed; then the sturgeon cultivated in a greenhouse is transferred to deep water net cages in a reservoir for commercial sturgeon cultivation; and finally, scientific feeding is performed until commercial sturgeon appears in the market. A novel cultivation mode of cultivating the commercial sturgeon in the greenhouse and the net cages is provided, according to the method, power consumption on year-on-year basis is reduced by 70%-80%, the labor cost can be reduced by 50%, the culture cycle can be shortened by 15-20 days, water resources can be saved, and the survival rate of the sturgeon can be increased and can reach more than 96%. In conclusion, the whole cultivation method can reduce cultivation costs and risks, and accordingly, economic benefits are increased.

Description

technical field [0001] The invention relates to a method for cultivating sturgeons, in particular to a new method for cultivating sturgeons in a greenhouse and then transferring them to deep-water net cages in a reservoir. Background technique [0002] Sturgeon is a cold-water fish with fast growth and tender meat. It is one of the special aquatic products with better economic benefits. At present, the main method of breeding sturgeon in East China is greenhouse constant-flow aquaculture. This method is to raise sturgeon at high density in square cement breeding ponds under the sunshade greenhouse. Generally, the size of the square pool is 8-10 meters long, 8-10 meters wide, and 1 meter high. PVC pipes are used for aeration in the pool, and a sewage outlet is designed at the bottom of the pool. In the breeding process, the breeding density of adult fish is generally controlled at 15-20 fish per square meter. The aerator must supply oxygen 24 hours a day. At the same time, t...

Problems solved by technology

Although the technology of this breeding method is relatively mature, during the growth process of the sturgeon, the leftover bait and excrement of the sturgeon accumulate in the pond, destroying the water quality of the breeding pond and affecting the environment required for the growth of the sturgeon. Moss will be produced, and only the constant flow of water through the pump will cause a great waste of water and power resources, as well as an increase in labor costs, which will eventually lead to high cost of commercial sturgeon farming and lack of competitiveness
