Description

technical field [0001] The invention belongs to the technical field of lobster cultivation, and in particular relates to a method for ecological cultivation 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. With the rapid development of the Australian freshwater lobster farming industry, high-density farming can easily lead to water quality deterioration and disease occurrence. In order to improve the survival rate, many people use chemical drugs and antibiotics in the Australian freshwater lobster farming process, causing Australian freshwater lobsters to gro...
