Abstract

The invention discloses a breeding method of young cherax quadricarinatus. The method comprises the following steps of 1, construction of a young cherax quadricarinatus breeding pond; 2, parent selection; 3, mating of breeding cherax quadricarinatus; 4, breeding of fertilized eggs; 5, breeding of young cherax quadricarinatus. By means of the breeding method of young cherax quadricarinatus, an optimal cherax quadricarinatus egg breeding environment is selected, the oogenesis rate of female cherax quadricarinatus is high, the hatching rate of young cherax quadricarinatus is high, the hatching quantity of young cherax quadricarinatus for single female cherax quadricarinatus reaches 200-300 at a time, young cherax quadricarinatus is reasonably fed, and the yield of young cherax quadricarinatusis effectively increased; meanwhile, a net cage device is arranged in the young cherax quadricarinatus breeding pond, the situation that parents eat young cherax quadricarinatus is effectively prevented, the survival rate of young cherax quadricarinatus is increased, and the economic benefit is obvious.

Description

Technical field: [0001] The invention relates to the technical field of shrimp seed breeding, in particular to a breeding method for Australian freshwater lobster seed. Background technique: [0002] Australian freshwater lobster is a low-living omnivorous animal. It likes to eat animal bait, such as aquatic insect larvae, animal carcasses, earthworms, etc. It also eats a small amount of water and tender grass, and adapts to artificial feed. It likes a quiet and hidden environment. During the breeding period of Australian freshwater lobster seedlings, parents are prone to cannibalism of seedlings, so the seedling breeding rate is low. In recent years, with the rapid development of intensive and high-density shrimp farming in my country, the breeding rate of seedlings is low and the problem of insufficient supply has become increasingly serious, which has become a limiting factor for the sustainable development of Australian freshwater lobster farming.
