Parent culture method in industrialized cultivation of giant salamanders

Abstract

The invention provides a parent culture method in the industrialized cultivation of giant salamanders, which adopts adaptive culture facilities and culture methods according to the physiological characteristics of the giant salamanders and the gonad development law of the parent; and the diversification and quantification of the fed bait meet the nutritional requirement of the giant salamanders in pre-reproductive period. Simultaneously, the invention adopts the method of combining group-culture with monoculture according to the characteristics of the reproductive performance of an individual giant salamander, conducts electronic marking on group-culture parents, establishes individual archive for each parent, adopts track management and well does jobs such as daily water exchange, feeding, antepartum culture and postpartum culture, overwintering management and prevention of diseases. The parent culture method greatly saves culture area, lowers culture cost, improves the culture capacity of a unit area by 4 to 6 times, and the artificial propagation performance of giant salamanders by 30 to 40 percent and increases culture benefit.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a method for cultivating parents in industrialized cultivation of giant salamanders. Background technique [0002] The breeding status of giant salamander parents is directly related to their reproductive results in artificial breeding. It is a very important basic work in the process of artificial breeding of giant salamanders. At present, in the industrial culture of giant salamanders, there is generally no specific method for parental breeding, and the breeding process is similar to the breeding of edible salamanders. The main purpose of the cultivation of edible salamanders is to pursue high density and fast growth, and to increase the growth period of edible salamanders by controlling the water temperature and increasing the amount of feed. The purpose of breeding giant salamander parents is to improve the reproductive ability of the parents. According to the physiological characte...

Problems solved by technology

Monoculture, that is, only one broodstock is raised in a pool, which avoids mutual bites and disease transmission between different individuals, and is convenient for understanding the feeding and development of the individual, but the disadvantage is that it takes up more breeding area and increases the cost.
