Sturgeon fry breeding method and breeding pond

Abstract

The invention discloses a sturgeon fry breeding method and a breeding pond. Sturgeon fry is placed into the breeding pond and bred through the following steps of 1, sterilization of the breeding pond; 2, controlling of quality of the sturgeon fry; 3, temporary rearing of the sturgeon fry; 4, mouth opening and feeding of the sturgeon fry; 5, alternative feeding of live baits and artificial diet and domestication; 6, disease prevention and control; 7, pond inspection and recording. According to the sturgeon fry breeding method and the breeding pond, different rearing methods are adopted according to requirements in different stages of sturgeon breeding, the survival rate of the sturgeon fry is high, breeding cost and risks are lowered, and economic benefits are raised.

Description

technical field [0001] The invention relates to the technical field of sturgeon cultivation, in particular to a method for cultivating sturgeon fry and a cultivation pool thereof. Background technique [0002] At present, there are some problems in the cultivation mode of sturgeon seedlings in cement ponds, which are mainly manifested in: (1) incomplete drainage of breeding wastewater; (2) slow water flow in the pond; (3) lack of water exercise for the breeding objects, poor physical fitness, etc. The reasons for these problems: the aeration method of conventional cement pools is air stone aeration, which is easy to stir up the bait and the dirt at the bottom of the pool and fill the entire water body, and the sewage discharge effect is poor; the water flow produced by air stone aeration is very weak and The water flow cannot form a circulation, and the water flow in the pool is slow; due to the lack of water flow exercise of the breeding objects, and the incomplete sewage d...

AI Technical Summary

Problems solved by technology

[0002] At present, there are some problems in the breeding mode of sturgeon seedlings in cement ponds, which are mainly manifested in: (1) Incomplete drainage of aquaculture wastewater; (2) Slow water flow in the pond; (3) Lack of exercise in water flow and poor physical fitness of the breeding objects, etc.

The reasons for these problems: the aeration method of conventional cement pools is air stone aeration, which is easy to stir up the bait and the dirt at the bottom of the pool and fill the entire water body, and the sewage discharge effect is poor; the water flow produced by air stone aeration is very weak and The water flow cannot form a circulation, and the water flow in the pool is slow; due to the lack of water flow exercise of the breeding objects, and the incomplete drainage of the breeding wastewater, the physique is weak, and it is easy to get sick and die

[0003] In addition, due to the specificity of sturgeon, breeding in late autumn and winter cultivation, the seedlings have weak disease resistance. In the process of artificially cultivating sturgeon fry, a large number of deaths will occur, and the survival rate is only 10-30%. , which has become a bottleneck restricting artificial breeding of sturgeon, therefore, we must formulate reasonable breeding methods to improve the survival rate of sturgeon
