Breeding method for prolonging mating Andrias breeding age

Abstract

The invention discloses a breeding method for prolonging mating Andrias breeding age and an apparatus, and the method comprises the steps of using a specific culture pond; forming a specific flow stimulation by increasing pool water volume of the mating Andrias gradually from early and mid march until the spawning induction breeding of the mating Andrias ends each year; and controlling the sexual gland growth, the resting and the body weight of the mating Andrias by seasonal bait feeding so as to prolong the breeding age of the mating Andrias. According to the method, the breeding age of the mating Andrias can be prolonged from 5-7 years to 7-10 years; the artificial breeding effect of the mating Andrias can be improved; the disease and mortality rate of the mating Andrias can be reduced; and the utilization value of the mating Andrias can be greatly improved.

Description

technical field [0001] The invention relates to a breeding technique of the giant salamander, in particular to a breeding method capable of prolonging the breeding life of the giant salamander and the equipment used therein. Background technique [0002] At present, in the breeding of giant salamanders, species of giant salamanders and commercial giant salamanders are not treated differently, and the breeding methods of the two are not clearly distinguished, or even completely the same. The same type of bait, feeding method and amount of feeding are used, and the perennial water culture is also carried out. , so that there is no big temperature difference in the water temperature of the breeding pond throughout the year; at the same time, the dosage of drugs used in the artificial breeding of giant salamanders to induce labor is increasing, and there is no hibernation habit in the natural environment to make the gonads well cultivated. Breeding salamanders with this feeding ...

Problems solved by technology

[0002] At present, in the breeding of giant salamanders, species of giant salamanders and commercial giant salamanders are not treated differently, and the breeding methods of the two are not clearly distinguished, or even completely the same. The same type of bait, feeding method and amount of feeding are used, and the perennial water culture is also carried out. , so that there is no big temperature difference in the water temperature of the breeding pond throughout the year; at the same time, the dosage of drugs used in the artificial reproduction of giant salamanders is increasing continuously, and there is no hibernation habit in the natural environment to make the gonads well cultivated.

Breeding salamanders with this feeding method has great defects: the main performance is that the weight gain is too fast, which makes the salamanders obese, the postpartum recovery and development of the gonads is poor, and even the gonads degenerate, which seriously affects and shortens the reproductive life of the salamanders.
