Description

A self-purification system for crab pond breeding with air lift push water and turn back type whole pond flow

technical field

The invention relates to the field of river crab cultivation, in particular to a self-cleaning system for crab pond cultivation with an air-lift push water turn-back type whole pond flow.

Background technique

River crab is the most important freshwater crab in China. Its meat is tender, delicious, rich in nutrition, and has high economic value. The culture of river crab in ponds is one of the main methods of river crab production. At present, river crab culture ponds mainly use still water ponds to plant aquatic plants for crab culture (that is, planting grass to raise crabs). This model has achieved certain success by planting grass and regularly changing water to ensure the habitat and growth environment of river crabs, but there are still some problems. Notable problems: (1) During the water change process, the waste water is discharged to pollute the surrounding water bodies, and the utilization efficiency of water resources is low. (2) Clean water aquaculture makes the dissolved oxygen in the pond water unsatisfactory, especially the oxygen content of the water at night. (3) Summer is the peak season for crab breeding, which is a critical stage for the growth of river crabs. However, the high temperature in summer makes the water temperature in the culture ponds high, and the growth and even survival of river crabs are threatened. (4) There are significant differences in the living conditions of still water culture in ponds and river crabs in the natural living environment, which hinders the further improvement of the quality of river crab culture, and it is urgent to realize the cultivation of crabs in running water.
