Description

A kind of high-yield disease resisting Mercuric chloride cultural method
Technical field
The present invention relates to animal plantation technology field, particularly relate to a kind of high-yield disease resisting Mercuric chloride cultural method.
Background technology
Mercuric chloride, is commonly called as Rana nigromaculata, is subordinate to subphylum chordata, Amphibia, Anura, Ranidae, Mercuric chloride genus, because head is big and tall sturdy, has the title of " frog in Asia ", is country second class protection animal.Being of high nutritive value of Mercuric chloride, containing 8 kinds of essential amino acids, in its muscle, the content of lysine is the abundantest, especially Thailand's Mercuric chloride, and its lysine content is up to 2.05%, significantly larger than the food such as Carnis Sus domestica, beef, egg, Trichiurus haumela.Mercuric chloride, in addition to rich in protein, also because of its fine and tender taste, delicious flavour, unique flavor, and is quite liked by consumers in general.But in recent years, owing to the factors such as artificial overhunting, habitat destruction, habitat degeneration and pesticide abuse cause Mercuric chloride wild resource amount deep fades, population quantity drastically declines, and is in Critical Condition, has loseed the trace of wild Mercuric chloride in certain areas.Owing to Mercuric chloride wild stocks drastically reduces, cannot meet the needs of consumption market, then expedite the emergence of Mercuric chloride artificial culture technology.Currently, China's problem encountered during the artificial cultivation of Mercuric chloride has: feedstuff kind is single, malnutrition, and palatability is poor, nutrition absorption rate is low, and hypoevolutism, quality decline, and breeding potential is the highest, disease-resistant performance is the strongest.Due to the existence of these problems, constrain the further development of Mercuric chloride cultivation, therefore it provides a kind of scientific and effective Mercuric chloride cultural method is most important for the healthy and sustainable development promoting Mercuric chloride aquaculture.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned technology, it is provided that a kind of high-yield disease resisting Mercuric chloride cultural method, improve the yield and quality of Mercuric chloride, strengthen its disease-resistant performance, improve efficiency of feed utilization, it is achieved the science healthy aquaculture of Mercuric chloride and benefit promote.
