    Wild B.C. salmon test positive for 'lethal' virus linked to fish farms  

    Fish farms, the gift that just keeps on giving.

    Wild sockeye salmon from B.C.'s Rivers Inlet have tested positive for a potentially devastating virus that has never been found before in the North Pacific.

    Infectious salmon anemia is a flu-like virus affecting Atlantic salmon that spreads very quickly and mutates easily, according to Simon Fraser University fisheries statistician Rick Routledge.

    ISA can be fatal to Atlantic salmon, especially those confined in fish farms. Its effect on wild sockeye is unknown.

    The virus detected in sockeye smolts by the Atlantic Veterinary College in P.E.I. — Canada's ISA reference lab — is the European strain of ISA, the same virus that devastated fish farms in Chile four years ago.

Disease not found in wild populations began to arise in hatchery fishes, and as early as the 1950’s scientists were starting to notice behavioral, and size changes as well as decreased genetic diversity. As fish became ...
