Problems solved by technology

[0004] However, at present, the breeding technology of red-clawed crayfish is not very mature, resulting in low breeding benefits of red-clawed crayfish. One of the very important reasons is the lack of special compound feed for red-clawed crayfish
At present, prawn compound feed is generally used as the feed for red-clawed crayfish in the cultivation of red-clawed crayfish. This will not only increase the cost, but also the digestion and utilization rate of the feed is not high, which will easily lead to deterioration of water quality and affect the red-clawed crayfish. growth
For example, the patent application with the application number 201710946870.1 discloses a method for ecological breeding of Australian freshwater lobsters, which feeds Australian freshwater lobsters with feed and chilled wild fish, wherein the feed is obtained by soaking and drying whole wheat flakes with probiotics.

Abstract

The invention discloses a method for breeding cherax quadricarinatus. The method includes the steps of preparation of a breeding pond, putting of cherax quadricarinatus seeds, breeding management andbreeding pond management, people pay attention to preparation work of the breeding pond before putting of the cherax quadricarinatus seeds and water quality optimization, and an external environment suitable for growth of cherax quadricarinatus is created; in addition, people pay attention to selecting and using of cherax quadricarinatus fodder. In the method, the fodder which is prepared from fish meal, barley pest powder, earthworm powder, shrimp shell meal, bean pulp, peanut meal, corn flour, wheat flour, soybean phospholipids, bone meal, lysine, methionine, multi-vitamins, composite mineral substances and other substances is selected and used, and is comprehensive in nutrient, has a remarkable promotion effect on growth of cherax quadricarinatus, the cost for breeding is low, breedingbenefits are remarkable, and the method is suitable for application and popularization of breeding of cherax quadricarinatus.

Description

technical field [0001] The invention belongs to the technical field of lobster cultivation, and in particular relates to a method for cultivating red-clawed crayfish. Background technique [0002] Red-clawed crayfish (Cherax quadricarinatus), also known as four-ridged crayfish, commonly known as "Australian freshwater lobster". Native to Australia, its appearance is similar to sea lobster, and it is one of the most valuable freshwater economic shrimp species in the world. [0003] The yield rate of red crayfish reaching commercial specifications is between 25.8-39.4%, with an average of 31.5%. The contents of water, protein, fat, ash, and nitrogen-free extracts in the muscle of red crayfish accounted for 79.92%, 17.49%, 0.42%, 1.28%, and 0.89% of the fresh weight, and their protein content was higher than that of prawns and Crayfish. are high and low in fat. Red crayfish muscle protein contains 18 kinds of amino acids, 8 of which are essential amino acids for human body. ...
