A kind of raising method for prolonging the breeding years of giant salamander species

Abstract

The invention discloses a breeding method and equipment for prolonging the reproductive lifespan of giant salamander species. It mainly utilizes a specific breeding pond, and gradually increases the breeding pond for giant salamander species during the period from the first to the middle of March every year to the end of the induced spawning and breeding of giant salamander species. The amount of water entering the pool will form a specific water stimulus, and the gonad development, self-cultivation and body weight of the giant salamander will be controlled through the seasonal distinction of bait feeding, so as to prolong the reproductive life of the giant salamander. Using the method of the present invention to raise the species of giant salamander can prolong the reproductive service life of the species of giant salamander, prolong the useful life of breeding from the original 5 to 7 years to 7 to 10 years, and can improve the effect of artificial reproduction of the species of salamander and reduce the breeding life of the species of salamander. Morbidity and mortality greatly increase the utilization value of giant salamander species.

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.
