Cherax quadricarinatus imitative ecological artificial scaled incubation culture technology

Abstract

The invention relates to the field of agricultural culture, and provides a cherax quadricarinatus imitative ecological artificial scaled incubation culture technology. The technology is particularly applicable to domestic gannan area climate culture, and fills the blanks in China. According to the technology, the complete ecological imitating incubation culture of the cherax quadricarinatus, particularly chrtax quadricarinatus is realized. Along with the lobster fertilization, before the stocking of lobster seeds into a pond, the sizes of stones, silts and water plants in an incubation pond are continuously changed for adapting to the growth of lobster seeds; the temperature and the diet are synchronously and scientifically managed; particularly through the unique design of the pond, the bottom layer is underground water, the top layer is flowing spring water, and the middle is water with proper water temperature; three kinds of different ecological environments provide the complete growth environment for the lobster; through the culture by the technical scheme, the cherax quadricarinatus can be cultured to be heavier than 0.8kg.

Description

Technical field [0001] The invention relates to the field of agricultural breeding, in particular to Australian freshwater lobster breeding. Background technique [0002] Australian freshwater lobster is native to Oceania and is a large-scale freshwater prawn introduced from Australia in recent years, including two species of red crayfish and crayfish. Australian freshwater lobster is also known as red crayfish, scientific name Cheraxquadriarinatus. Originally a wild shrimp, it was cultivated artificially in 1971. It is currently one of the best freshwater shrimp in the world. The shrimp lives in fresh water for life, is omnivorous, has a faster growth rate, can naturally reproduce and hatch in fresh water, has a higher survival rate and strong disease resistance, weak aggressiveness, low oxygen resistance, and pollution resistance , Strong adaptability, tender meat, delicious taste, high edible ratio (abdomen accounts for 42% to 47% of the total weight), and has the advantages...

Problems solved by technology

[0003] The breeding technology of Australian freshwater lobster in China is not yet mature, and there is a lack of a complete set of standards. In addition, the shrimp seedlings of Australian freshwater lobster often die in large pieces, which puts great economic pressure on the farmers, and there is an urgent need for a set of domestic Australian freshwater lobster. Breeding methods, due to the different climates in various places, especially in southern Jiangxi, there is still a blank
