Problems solved by technology

However, because the water environment for the reproduction and seedling cultivation of river crabs is the chloride-type water quality in offshore areas, it cannot adapt to the inland soda-type saline water environment under natural conditions, and must be properly domesticated to make river crab seedlings produce certain Can be stocked only after adaptability
[0003] At present, there are not many research reports on the cultivation and domestication of river crabs in inland soda-type saline-alkaline water environment, let alone related patents

Abstract

The invention belongs to the technical field of aquaculture, relating to a river crab domesticating method for river crab ecological breeding in a soda type salinized reed wetland. The method mainly solves the problem that river crabs cannot survive in a soda type salinized water environment. The method is characterized in that: water quality analysis is used as basis, and a domesticating method by manually prepared basic water with salinized water in the reed wetland and domesticating speed that the alkalinity of the domesticating water is improved by 2mol.m<-3> every 12 hours are adopted. The method ensures that the river crabs can generate an adaptability mechanism to the soda-type salinized water environment in short time, and the domesticating survival rate of the river crabs with the specification of between 3 and 6 grams per river crab for 5 to 7 days can reach 87.49 percent, thereby achieving the stocking requirement.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a crab species domestication method for ecological cultivation of river crabs in soda-type salinized reed wetlands. technical background [0002] The development and utilization of natural reed wetlands to cultivate river crabs (Eriocheir sinensis) and establish a reed-crab composite ecological structure is an efficient economic utilization model of reed wetlands. It is also a better way for the sustainable use of reed wetlands. As one of the important ecological types of inland swamp wetlands, soda-type salinized reed wetlands are widely distributed in the west of Northeast China. The natural bait resources such as benthic animals and submerged plants in the wetlands are abundant, which are suitable for the development of the ecology of river crabs. breeding. However, because the water environment for the reproduction and seedling cultivation of river crabs is the chloride-t...
