Problems solved by technology

It is characterized by excessive water consumption, high power consumption, simple treatment of water quality, and difficulty in increasing production. Most of the aquaculture wastewater is directly discharged into the sea without treatment, causing sea area pollution and endangering the long-term survival of the enterprise itself.
In recent years, industrialized recirculating aquaculture system (RAS) has gradually developed in China, but it is still in its infancy

Embodiment 1

[0037] Such as Figure 2 to Figure 5 Shown a kind of three-dimensional polyculture method and production system of salmon trout flounder flounder:

[0038] (1) Polyculture system

[0039] The polyculture system is an indoor closed circulation aquaculture system. Each circulating water system includes 5 breeding ponds and 1 set of water treatment facilities; the breeding ponds are connected in series, and the volume of each breeding pond is 120m 3 , whose shape is a regular octagon, with a circumcircle radius of 3.5m and a height of 3m. Water treatment facilities and equipment include sewage collectors, solid-liquid separators, plate filters, protein separators, biofilters, ultraviolet sterilization devices, and LHO aeration devices; the water treatment process is: culture pond-solid-liquid separator (80 % water directly enters the plate filter pool)--plate filter-protein separator (80% of the water directly enters the high-level pool for aeration)-first-level biological poo...

Abstract

The invention relates to the technical field of for cultivating salmon and trout and provides a solid mixed cultivation method for salmon and trout flatfish. The salmon and trout and the flounder are cultivated in a same cultivation pool together. The use ratio of the cultivation water can be greatly improved by the complementary feature of life water of salmon and trout and the flounder, and then the unit water yield and effect are improved; and the maximum economic benefit is realized by using the limited water resource.

Description

technical field [0001] The invention relates to the technical field of salmon and trout culture, in particular to a three-dimensional polyculture method and production system of salmon, trout, flounder and flounder. Background technique [0002] Salmon trout is a collective term for salmon and trout. Atlantic salmon is the most common type of salmon trout. Atlantic salmon (salmon salar) belongs to Salmoniformes, Salmonidae, Salmon genus, commonly known as "salmon". Most of the Atlantic salmon produced in the world (99%) are artificially raised. The artificial breeding of migratory Atlantic salmon is carried out in fresh water, and the adult fish breeding stage is carried out in seawater, which is essentially different from the land-sealed Atlantic salmon that has been cultured in fresh water for a lifetime. Migratory Atlantic salmon is more suitable for intensive farming. It is characterized by high economic value, fast growth, strong disease resistance, and better taste....
