Method for artificially breeding giant salamanders

Abstract

The invention discloses a method for artificially breeding giant salamanders, and belongs to aquatic products breeding methods. The method for artificially breeding giant salamanders aims to improve giant salamander population. The method comprises mother giant salamander domesticating, antenatal breeding, parturient breeding, egg laying and hatch breeding and young giant salamander breeding. According to the method, male giant salamanders and female giant salamanders are put into domesticating pools with temperature of about 14 DEG C to be carried out isolation feeding for about three months, the male giant salamanders and the female giant salamanders are put into an identical pool to be fed in the last ten-day of July, live crucian carps or loaches are fed to the giant salamanders every day and water temperature is controlled between 18 DEG C to 22 DEG C for continuous 15 days. After the giant salamanders lay eggs and the eggs are fertilized, live crucian carps or loaches are fed to the giant salamanders every day, the flow speed of pool water is controlled at 0.1 m<3> / s, and after the newborn giant salamanders come out of egg films, the newborn giant salamanders are shifted to a feeding pool with water depth of 5cm. Chironomidae larvae are fed to the newborn giant salamanders once a week after 30 days, and the newborn giant salamanders can grow into young giant salamanders after 6 to 8 months. The method for artificially breeding the giant salamanders can achieve the synchronous growth of the sexual glands of the male giant salamanders and the sexual glands of the female giant salamanders, and improves the success rate of giant salamander breeding and the survival rate of the giant salamander, and is a method of breeding the giant salamanders commercially.

Description

technical field [0001] The invention relates to a method for artificially breeding giant salamanders, in particular to a method for artificially breeding giant salamanders. Background technique [0002] Giant salamander, commonly known as giant salamander, is one of the more primitive species of existing amphibians and is a second-class protected aquatic wild animal. Giant salamanders are easily affected by the external environment. It is difficult to restore the population of giant salamanders by relying on natural protection and natural multiplication methods, and it is even more difficult to meet market demand. Artificial breeding must be adopted. However, giant salamanders have relatively strict requirements on the living environment, and their natural fecundity is low. If artificial methods can be used to simulate and create a simulated ecological environment that conforms to the natural growth habits of giant salamanders, it will undoubtedly greatly promote the develop...

Problems solved by technology

Giant salamanders are easily affected by the external environment. It is difficult to restore the population of giant salamanders only by relying on natural protection and natural multiplication methods, and it is even more difficult to meet market demand. Artificial breeding must be adopted.
