Fish culture circulating countercurrent water channel near river

Abstract

The invention belongs to the field of fish culture equipment, and relates to a fish culture circulating countercurrent water channel near a river and a culture method. The fish culture circulating countercurrent water channel close to the river is provided with a single culture flow channel or a plurality of culture flow channels in the river channel, and the culture flow channels are arranged inparallel; the inflow end of the single culture flow channel or the plurality of culture flow channels faces the reverse flow direction of the river channel; isolation water channels are arranged at the outflow ends of the single culture flow channel or the multiple culture flow channels, and water flow in the river channel flows into the culture flow channels from the inflow ends of the single culture flow channel or the multiple culture flow channels and flows into the river channel water flow from the isolation water channels. The fish culture circulation reverse flow water channel close tothe river can be adjusted according to the water amount and the water flow speed in the flood season and the dry season of the river, and the culture environment in the culture water channel is guaranteed.

Description

technical field [0001] The invention belongs to the field of fish breeding equipment, and relates to a fish breeding circulation countercurrent waterway near a river and a breeding method. Background technique [0002] Aquaculture is a production enterprise that uses suitable waters to breed aquatic economic animals and plants. important part of the fishery. The period when humans engaged in aquaculture was later than the fishing industry for harvesting natural aquatic resources. The emergence and development of aquaculture marks the enhancement of human ability to influence and control waters. In aquaculture waters, aquaculture can be divided into freshwater aquaculture, marine aquaculture, and shallow beach aquaculture; according to aquaculture objects, it can be divided into fish aquaculture, shellfish aquaculture, shrimp aquaculture, crab aquaculture, and algae cultivation; It is intensive culture, extensive culture, monoculture, polyculture, factory culture, hydros...

AI Technical Summary

Problems solved by technology

[0003] Because the production of exotic fish in waterways or lakes is relatively large, the waste produced will pollute the existing rivers or lakes. Secondly, a large number of exotic species will threaten the native species in the water area and destroy the ecological balance. Secondly, the river itself The flow rate fails to make maximum use of
