Abstract

The invention discloses a breeding method for improving the survival rate of Australian freshwater lobsters. The breeding method comprises the following steps of pond selection, pond sterilization, breeding water treatment, young lobster stocking, compound bacterium culture, feed putting and pond management. By reasonably arranging shelters, placing tourmaline, stocking compound bacteria, feedingdifferent feeds at different growth stages and adopting other modes, breeding is performed without hormones and antibiotics, the breeding method has the advantages of being environmentally friendly, free of pollution, small in investment, low in cost and convenient to manage, bred Australian freshwater lobsters are high in growth speed, healthy and strong in physique condition and strong in disease-resistant capability and stress resistance, and the survival rate reaches 95% or above.

Description

technical field [0001] The invention belongs to the technical field of lobster cultivation, and in particular relates to a cultivation method for improving the survival rate of Australian freshwater lobsters. Background technique [0002] Australian freshwater lobster (Cherax quadricarinatus), whose scientific name is four-ridged light-shelled crayfish, also known as red-clawed crayfish, is a large freshwater crayfish belonging to the decapod Crayfish family. It is called Australian freshwater lobster because it is large in size and looks a bit like a lobster in the sea, and because it is native to Australia and only lives in fresh water. [0003] Chinese patent 201610394121.8 discloses a method for cultivating Australian freshwater lobsters, including selection of shrimp ponds, disinfection of ponds, water cultivation, feeding of shrimp seedlings, feeding of feed, and management of shrimp ponds. Applying bio-fertilizers to the water body to improve the water body can not o...
