Abstract

The invention belongs to the technical field of culture and particularly relates to an ecological culture system of river crabs. The ecological culture system comprises an isolation assembly, a drivemechanism for conveying is arranged on one side of the isolation assembly and is connected with a cleaning assembly for cleaning, two switching assemblies used for switching the cleaning assembly arearranged on two sides of the cleaning assembly, the switching assemblies are distributed at two ends of the isolation assembly, a blocking assembly connected with the isolation assembly is arranged atthe bottom of the cleaning assembly, and the ecological culture system further comprises an application method of the ecological culture system of the river crabs. By the arrangement, the river crabsare cultured, irrigation canal water grass is removed, the irrigation canal safety is protected, salvage of floating matter is facilitated, feeding is facilitated during culture, the culture efficiency is improved, aquatic plants in irrigation canal riverway are removed, and the riverway is dredged.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to an ecological breeding system for river crabs. Background technique [0002] Natural river crab is rich in nutrients and has become a delicacy in people's meals. The cultivation methods of adult crabs in my country include: crab cultivation in ponds, beach cultivation, net enclosure cultivation, rice field cultivation, garden cultivation and so on. The characteristic of crab culture in ponds is that it uses high density to promote growth and disease prevention by feeding feed and medicine. The whole process of breeding can be controlled artificially, and the return rate is high; it is easy to cause serious water pollution and pollution in a small water body environment. The disadvantage of poor quality of adult crabs. Dangtan breeding site is suitable for the ecological requirements of river crab growth, with low production cost, large market size and good quality, but its ca...
