Embodiment Construction

[0016] The technical solution of the present invention will be further specifically described below, instead of limiting the present invention.

[0017] The imitation ecological artificial scale hatching and breeding technology of Australian freshwater lobster includes the following steps:

[0018] (1) Maternal mating stage: Take one male prawn with more than three or two healthy and strong limbs, and three female prawns with more than two or two healthy and strong limbs, and put them in the hatching tank together with 20~25℃ clean water. When the female prawn and the male prawn are together, their tails need to be turned back. After mating is completed in about 15 days, one female prawn will be eliminated and attacked by the male prawn, and the eliminated female prawns will be taken away separately;

[0019] (2) 15 to 30 days: implement imitation ecological incubation, add river sand, pebbles, and aquatic plants in the hatching pond. After conception, the two female prawns begin to ...

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...
