Harbour seals prime suspect in decline of steelhead populations in Thompson watershed
Rob Bison, a fish stock biologist, gave a live-streamed presentation on factors that could be contributing to the steelhead’s decline,,, The fish populations in the two rivers have been declining over the last 30-40 years, but it’s likely not their stream habitats that have led to the decline, he said. The drastic decline in steelhead appears to happen when the fish reach inshore waters and are eaten by harbour seals,,, Bison estimated that by reducing seal populations, steelhead populations could increase by 486%. >click to read< 13:03
Seal cull not yet warranted despite large salmon diet say researchers
Harbour seals off B.C.’s South Coast may consume up to 60 per cent of the Strait of Georgia’s young chinook and coho salmon every year, according to UBC research. Growing concerns about B.C.’s salmon numbers has focused on orca populations and rising water temperatures in the past, but this study suggests the dramatic increase in the harbour seal population in recent decades may play a role as well. Still, the connection between low salmon stocks and a large harbour seal population is not clear enough to warrant a seal cull, scientists warn. Read the foolishness here 10:49
