Crayfish-rice co-culture ecological culturing and breeding method

Abstract

The invention provides a crayfish-rice co-culture ecological culturing and breeding method. The method is characterized by particularly comprising the following steps of 1 rice field preparing, 2 rice field disinfecting, 3 aquatic plant transplanting, 4 crayfish seed stocking, 5 crayfish seed managing and 6 crayfish seed fishing. According to the method, a batch of crayfish seeds are harvested in March to April, the first batch of commercial crayfishes are harvested in April to May, and the second batch of commercial crayfishes or parent crayfishes are harvested in August to September; the culturing limitation of the prior art is reduced, ecological resources are utilized, the problem that in the existing mode, the yield is low, and the death rate is high are avoided, combined and cooperative culturing of ecological rice and crayfishes is achieved to a great extent, the crayfish culturing yield is increased, and the crayfish culturing quality is improved.

Description

technical field

[0001] The invention relates to a method for ecological cultivation and breeding of crayfish, shrimp and rice. Background technique

[0002] The breeding of crayfish is divided into natural breeding and artificial breeding. Artificial breeding includes rice field breeding (semi-artificial breeding in rice field and ecological breeding in rice field), earth pond breeding, earth pond greenhouse breeding, cement pond breeding and factory breeding. Breeding in paddy fields, earthen ponds, and greenhouses in earthen ponds mainly produce large-sized shrimp seedlings of about 3 cm in March to April, and cement pond breeding and industrial breeding produce small-sized shrimp seedlings of 1-2 cm in September to October each year. From the perspective of long-term production practice, natural multiplication is only suitable for the extensive breeding mode of human free-range breeding, and cannot form seed supply; artificial breeding, whether it is half-manual breeding ...
