A kind of method of cultivating salamander in freshwater lake area

Abstract

A method for cultivating giant salamanders in freshwater lake areas, using non-pollution or low-pollution bicarbonate calcium group freshwater lakes as a breeding area to build aquaculture ponds, mixing deep well groundwater with freshwater lake water in proportion, and mixing the mixed water body As an environmental water body, salamanders are cultured, and the snail meat and mussel meat native to the lake area are used as raw materials to prepare bait with eggs, allicin, gallnut and rhubarb powder to promote the salamanders to adapt to the environment of the lake area. Stocking is carried out in the marble nests in the shoal area of ​​the waters. The invention can effectively reduce the feeding cost of the salamander, improve its survival rate, facilitate the large-scale and industrialized breeding of the salamander, and the meat quality of the raised salamander is excellent, and the taste is crisp and tender.

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 ...

AI Technical Summary

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.
