B.C. Virus in Freshwater Farmed Fish
A virus linked to the death of farmed salmon has for the first time been found in B.C. freshwater fish — cutthroat trout in Cultus Lake, a research team reported Thursday.
Seventy-five per cent of 404 Atlantic salmon tested positive for the virus compared with 61 per cent for 58 Pacific salmon — all on farms.
He said he was involved in a similar study on herring after the 1989 Exxon Valdez supertanker oil spill in Alaska and discovered “two different disease processes that changed over time that were clearly limiting the recovery of that population.”
