FROM SEAFOOD SOURCE: Canada’s Department of Fisheries & Oceans (DFO) disclosed yesterday (April 18) that 2,745 farmed Chinook salmon (Oncorhynchus tshawytscha) escaped on March 12 from the Vancouver Island/British Columbia demonstration farm of the “leader in floating solid-wall containment technology and production for sustainable aquaculture”, AgriMarine Holdings Inc.
“An extreme storm event caused damage to the containment structure at their facility in Middle Bay, allowing some fish, averaging 2.1 kg, to escape…,” DFO wrote. This regrettable incident is noteworthy because closed-containment technologies have been hailed by many salmon farming critics and eNGOs as being ‘the future’ of marine finfish aquaculture, notably because they made fish escapes supposedly impossible…
No other fish escapes were reported from other ‘conventional’ salmon farms in BC. On March 14th, AgriMarine had reported “some storm related losses”. On March 21, Robert Walker, President of AgriMarine Industries, had told SeafoodIntelligence: “… Until we completely empty the tank we won’t know the final number, but at this time it appears that we did not lose any fish.”
The Toronto, OTCQX & Frankfurt stock-listed firm has not yet communicated on the escapes. The firm said it had filed a report with the feds on March 14. Yesterday, a top salmon farmer (Cermaq) stated in its 2011 Report that “Closed-containment technology does not currently represent a viable alternative, especially related to energy usage but also [fish] escapes remain a risk in closed containment farming.”
