Method for cultivating giant salamander in freshwater lake region

Abstract

The invention provides a method for cultivating giant salamander in a freshwater lake region. A bicarbonate calcium freshwater lake free from pollution or low in pollution is utilized as a cultivation region to build a cultivation pond, underground water of a deep well and lake water of the freshwater lake are mixed according to the proportion, the mixed water serves as environment water to cultivate the giant salamander, protogenic spiral shell meat and clam meat in the lake region are matched to serve as raw materials, the raw materials are mixed with eggs, allicin, gallnut and rheum officinale powder to prepare bait so as to promote the giant salamander to adapt to the environment of the lake region, and the giant salamander is transferred into a granite nest in a shoal region of a natural water region of the lake to be bred outside after growing into adults. The method can effectively reduce the feeding cost of the giant salamander and increase the survival rate of the giant salamander, the giant salamander can be cultivated conveniently in a large-scale and industrial mode, and meat of the raised giant salamander is sturdy, crisp, tender and excellent in taste.

Description

technical field [0001] The invention relates to salamander breeding technology in the field of special aquaculture, in particular to a method for cultivating salamander in freshwater lake areas. Background technique [0002] Giant salamander is commonly known as giant salamander in my country. It likes shade and is afraid of light, and its growth rate is slow. Its suitable temperature range is 16-25°C. When the water temperature is below 10°C or above 26°C, its food intake will decrease. When the water temperature drops below 4°C, it begins to hibernate, and when it rises above 28°C, it enters into aestivation, and they all stop eating completely. For a long time, salamander has been a favorite food of the upper-class consumers in my country. It is delicious, nutritious, and has excellent medicinal value, ornamental value and scientific research value. In addition, with the development of social economy and the improvement of people's living standards Improvement, some body ...

Problems solved by technology

And when carrying out artificial culture giant salamander, adopted many kinds of methods to carry out artificial breeding to giant salamander, but basically all adopts imitation wild breeding method, the problem that male and female plant grow out of sync easily occurs in its breeding process, and usually needs 2 It takes one and a half years to three years or even longer to reach maturity. The cultivation cycle is long and the survival rate is low, which cannot meet the needs of the market.
