Closed-Containment Salmon Tanks Installed in BC

A company in British Columbia, Canada is in the process of installing and testing floating tanks to grow chinook salmon (Oncorhynchus tshawytscha), a species that occurs naturally in these waters.  The tanks are essentially closed pens, with fresh seawater being pumped in and excess food and feces being pumped out.  These systems have vast advantages over conventional open-net pens, where wastes are allowed to enter the surrounding environment.  Additionally, the water being pumped into and out of the tanks can be filtered and treated, minimizing the risks of parasites and disease.  Overall, if proven economically viable at a commercial scale, this will be a large step towards the sustainability of the aquaculture industry!
