挪威在饲养鲑鱼苗种方面有悠久历史,为了在寒冷季节内生产一龄鲑,池水必须加温。但是只有在利用热交换器、热泵,使养殖用水循环使用时,才能使加温费用降到比较经济的程度。对于水资源有限或水质较差的种苗场建议也采用循环水系统。挪威已建有一些循环水养殖系统,有一些苗种场已经从使用这种系统中获益。其他国家已经在循环水养殖场内生产虹鳟,但是大西洋鲑是一种对水质要求更高的鱼种。我们研究的目的是设计一座可 Norway has a long history of raising salmon species and in order to produce first-term salmon in the cold season, the water must be warmed up. However, only by using heat exchangers and heat pumps to recycle farming water can heating costs be reduced to a relatively economical level. Reclaimed water systems are also recommended for seedling farms with limited water resources or poor water quality. Some recirculating aquaculture systems have been established in Norway and some seed farms have benefited from the use of such systems. Other countries have produced rainbow trout in recirculating aquaculture farms, but Atlantic salmon is a species that requires higher water quality. The purpose of our research is to design one
