Factory-like recirculating aquaculture system for Hucho taimen

Abstract

Provided is a factory-like recirculating aquaculture system for Hucho taimen, pertaining to the technical field of aquaculture. The key points of the system are described in that outlet ends of aquaculture ponds communicate with a sedimentation pond through pipelines; the sedimentation pond is located on the side of the aquaculture ponds; a microfiltration machine pond is arranged on the side of the aquaculture pond; additionally, an outlet end of the sedimentation pond communicates with an inlet end of the microfiltration machine pond; the side of the microfiltration machine pond is equippedwith a water return pond; aquaculture water at an outlet end of the microfiltration machine pond and an inlet end of the water return pond as well as in the water return pond enter a floating ball-type biological filter through a pipeline and a water pump; an outlet of the floating ball-type biological filter communicates with a trickling filter through a pipeline and a water pump; the trickling filter is located above an oxygenating tank; the oxygenating tank is disposed on the side of the water return pond; the interior of the oxygenating tank is equipped with an ultraviolet radiation disinfection device; the ultraviolet radiation disinfection device communicates with the oxygenating tank; water in the oxygenating tank communicates with the aquaculture ponds through pipelines. The factory-like recirculating aquaculture system for Hucho taimen is used for factory-like aquaculture of Hucho taimen.

Description

technical field [0001] The invention relates to a recirculating aquaculture system for cymbals, in particular to an industrialized recirculating aquaculture system for cymbals, which belongs to the technical field of aquaculture. Background technique [0002] Hucho taimen (Hucho taimen) is a rare and rare large-scale cold-water fish of the family Salmonidae, belonging to the order Salmoniformes and the genus Hucho taimen. in a river or stream. It is large in size, fast in growth rate, tender in meat quality, delicious in taste, and has extremely high nutritional value. In recent years, the ecological environment of the aquaculture waters has been destroyed, which has greatly reduced the distribution area of ​​the salmon, and the natural resources have declined sharply, and it is already in an endangered state. According to the International Union for Conservation of Nature's (IUCN) classification standard for threatened species, the salmon is already an endangered aquatic ...

AI Technical Summary

Problems solved by technology

At present, industrial recirculating aquaculture systems have been widely used in developed countries such as Europe and the United States. In my country, the use of recirculating aquaculture systems to breed fish such as rainbow trout, flatfish, shrimp, eel, puffer, and grouper has been preliminary. The recirculating aquaculture mode or semi-recirculating aquaculture mode has been realized, but the recirculating aquaculture system of panacea is rarely reported
