River crab integrated culture method in ponds

Abstract

The invention discloses a river crab integrated culture method in ponds. The river crab integrated culture method in the ponds comprises the following steps of preparing the ponds; equipping the ponds with escape-proof facilities, water inlet and drainage facilities and bottom aeration facilities; breeding snails, river crabs, freshwater shrimps, dark sleepers and Aristichthysnobilis; planting aquatic plants; feeding feedstuff; managing water quality and sloughing. According to the river crab integrated culture method in the ponds, the ecological layout is adjusted, the self-purifying capacity of the ponds is improved, the pressure exerted on creatures by eutrophication of a water environment and the ponds can be released, the ecological balance and the stabilization of the water quality can be kept, and accordingly the disease incidence are reduced and the foundation for achieving high and stable yields is laid; meanwhile, existing culture facilities are fully taken advantages of, the comprehensive productivity of the ponds is improved, and accordingly the overall economic benefits are improved. The river crab integrated culture method in the ponds is beneficial to utilizing solar energy and the feedstuff to the utmost, preventing diseases and improving the capacity of resisting natural and market risks. Through the embodiment of the river crab integrated culture method in the ponds, the disease incidence of the crabs cultured in the ponds can be reduced, and the culture loss and culture risks can be reduced. The predicted comprehensive benefits of the culture can be improved, and meanwhile the pollution of the ecological environment of a water area caused by the culture can be reduced.

Description

technical field [0001] The invention belongs to the technical field of river crab cultivation, in particular to a method for comprehensive cultivation of river crabs in ponds. Background technique [0002] River crabs belong to the class Crustacea and the genus Eriocheir. It is a large crustacean with a body divided into 21 segments. Since the head and thorax are healed with each other, the whole body is divided into two parts: the cephalothorax and the abdomen. The back of the adult crab is dark green. The ventral surface is off-white, the average length of the carapace is 6-7cm, and the width is 7.5cm. River crabs often live in caves on the mud banks of rivers, rivers, and lakes. They are nocturnal and feed on fish, shrimp, animal carcasses, and grains. They often migrate to the sea every autumn. The estuary of the river lays eggs, and hatches from March to May in the second year. After developing into young crabs, they go up the river and continue to grow up in fresh wate...
