Sturgeon artificial propagation tank and propagation method

Abstract

The invention discloses a sturgeon artificial propagation tank and a propagation method, and belongs to the field of fish farming. The sturgeon artificial propagation tank and the propagation method can achieve real-time temperature control and guarantee the quality of sturgeon oviposition. According to the technical scheme, a water inlet pipe and a water outlet pipe are arranged on the sturgeon artificial propagation tank, a pollutant discharge pipe is arranged at the bottom of the sturgeon artificial propagation tank, liquid oxygen is injected into the sturgeon artificial propagation tank, atemperature sensing device is arranged in the tank to measure the water temperature in real time, parent fishes are selected to be bred for one month or longer in the propagation tank at the temperature of 10 DEG C, the parent fishes are transferred into an incubation pool at the temperature of 12-13 DEG C, oxytocin is used on the parent fishes, semen is collected, spawn is collected for artificial fertilization, and artificial incubation is conducted. The method can be widely applied to the field of fish farming.

Description

technical field [0001] The invention relates to a sturgeon artificial breeding tank and a breeding method, which belong to the technical field of fish breeding. Background technique [0002] In the industrialized culture of sturgeon, water temperature is the most important environmental factor for breeding broodstock. The suitable water temperature for breeding sturgeon is 4-10°C. Therefore, if the sturgeon is cultivated in a water temperature that continues to exceed 15°C, the gonads of the broodstock can grow, but up to If it is not mature enough, it cannot ovulate normally. Even if it ovulates eggs, they are abnormal eggs. The fertilization rate and eye formation rate are very low. Therefore, the physiological maturity of sturgeon requires low temperature stimulation of not less than two months before birth. Generally, the low temperature is 4 ~6°C, the existing methods of artificial breeding of sturgeon cannot effectively control the temperature of the physiological need...

Therefore, the physiological maturity of sturgeon requires low temperature stimulation of not less than two months before birth. Generally, the low temperature is 4 ~6°C, the existing method of artificial breeding of sturgeon cannot effectively control the temperature of the physiological needs of the sturgeon, it is difficult to guarantee the spawning rate of the sturgeon, and it cannot guarantee the qualified spawning of the sturgeon, which cannot meet the needs of the market
