Method for breeding cherax quadricarinatus

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. ...

AI Technical Summary

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. Single, and chilled wild fish are difficult to digest for Australian freshwater lobsters that have been stocked recently, and the utilization rate is not high, which will inevitably have a negative impact on water quality; another example is a patent application with application number 201610394121.8, which discloses an Australian freshwater lobster. The method comprises feeding the feed made from red worm powder, fish meal, snail meat powder, river clam meat powder, weedus, wheat gluten, emerald mussel powder, wild rice husk, carrot dregs and traditional Chinese medicine additives, wherein the traditional Chinese medicine additive components are Tripterygium wilfordii, Radix japonicus, Fragrant tea vegetables, Gynostemma pentaphyllum, Mistletoe, Bean root, Fangji, Comfrey, Polyporus and Cucumber are rich in feed nutrition, but the cost of raw materials is high, so it is difficult to popularize and apply
