Culture method for increasing survival rate of crays

Abstract

The invention provides a culture method for increasing survival rate of crays. The method includes: (1) building a culture pond which is a trapezoid, arranging a ridge at the position of the center line of the culture pond, and dividing the culture pond into a first pond and a second pond via the ridge; (2) constructing cray caves, to be more specific, forming the caves in the side walls of the first pond and the second pond; (3) pretreating the culture pond, leveling the first pond and the second pond, and performing desludging, airing and disinfection; (4) performing fertility betterment of water; (5) putting in aquatic plants, tying the aquatic plants into stacks with ropes, and putting the stacks into the bottoms of the first pond and the second pond at an interval of 5 meters; (6) putting in cray fries; (7) putting in feed, to be more specific, putting in cray feed twice every day; (8) performing later period management. In the cray culture process, the crays are cultured in the first pond and the second pond alternatively so as to disinfect the first pond or the second pond thoroughly, and survival rate of the crays is increased.

Description

technical field [0001] The invention belongs to the field of crayfish culture, in particular to a culture method for improving the survival rate of shrimp. Background technique [0002] The nutrition of crayfish is well known. At present, crayfish farming is developing rapidly in our country. During the growth process of crayfish, crayfish are prone to infection of diseases, and at the same time, they often bite each other, resulting in that the output of crayfish cannot be effectively increased. economic benefit. [0003] In the process of cultivating crayfish, providing a good growth environment for the growth of crayfish, timely disinfection and sterilization can effectively improve the survival rate of crayfish and improve economic benefits. Contents of the invention [0004] An object of the present invention is to solve at least the above-mentioned problems or disadvantages and to provide at least the advantages that will be described hereinafter. [0005] Another ...
