Atlantic salmon is mainly cultured in cages abroad, but in China, it is necessary to explore indoor industrialized recycling culture. However, because water is recycled, whether it can maintain a stable water temperature in summer and winter puts forward high requirements for the thermal insulation technology of the maintenance structure of aquaculture greenhouse.
There are several technical difficulties in "industrialized circulating aquaculture of Atlantic salmon": first, whether the Atlantic salmon produced by industrialized circulating aquaculture system can reach the same level as that produced by cage culture abroad in terms of growth speed and product quality; second, the problem of epidemic disease control in circulating aquaculture system; and third, whether the existing feed, including imported feed, is suitable for the requirements of circulating aquaculture water treatment system.
