Factory-like circulating water breeding method for hucho taimen

Abstract

The invention relates to a factory-like circulating water breeding method for hucho taimen, and belongs to the technical field of aquaculture. The method is characterized in that a hucho taimen circulating water breeding system is connected with a hucho taimen juvenile fish breeding system, juvenile fishes are subjected to tameness and cultivation and parallel screening in sequence, fish fry of different sizes are put into multiple breeding ponds respectively, water drained from the breeding ponds passes through a settling pond and a micro filter tank, and then residual feed and fecal suspensions are filtered and removed; detection is conducted by means of a PH online monitoring system, and the PH value of breeding water is adjusted; the breeding water enters a floating type biofilter through a water pump to remove organic matter such as ammonia nitrogen, nitrate and nitrite; harmful gas such as CO2 is removed in a trickling filter; pure oxygen is increased in an oxygen increasing groove; water obtained after oxygen increasing is subjected to ultraviolet ray disinfection; finally, the breeding water automatically flows into the breeding ponds through an oxygen increasing high-levelwater tank, and the whole hucho taimen circulating water breeding process is completed. The method is used for factory-like hucho taimen breeding.

Description

technical field [0001] The invention relates to a method for circulating aquaculture of chrysalis, in particular to a method for industrialized circulating aquaculture of chrysalis, belonging 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...

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
