Ecologic breeding method of river crabs

Abstract

The invention belongs to the field of special aquatic product ecologic breeding and particularly relates to an ecologic breeding method of river crabs. The ecologic breeding method of the river crabs includes the following steps that a crab pool for breeding the river crabs is selected; before water plants are planted, fertilizer and water management on the crab pool is carried out; water caltrop and hydrilla varticillata are planted; young crabs are put for breeding; the river crabs are bred and harvested. By means of the method, the problem that the river crabs cannot be bred in places in the south of the 28-degree northern latitude on a large scale due to high temperature is effectively solved.

Description

technical field [0001] The invention belongs to the field of ecological cultivation of special aquatic products, and in particular relates to a method for ecological cultivation of river crabs. Background technique [0002] Eriocheir sinensis is currently one of the famous and high-quality cultured species in my country's inland waters. Its breeding scale is gradually expanding, and its breeding output is continuously increasing. Ecological breeding of river crab ponds refers to the correct use of the symbiosis and mutual benefit or mutual restraint relationship of aquatic organisms in the same water body to meet the requirements of biodiversity in the water environment, realize the virtuous cycle of materials in the aquatic ecosystem, and enhance the self-purification and self-sustainment of the water body. The function is to obtain high-quality river crabs with high economic benefits without damaging the ecological environment of the water area. In some areas, due to the ...
