Scientists are launching a new video to call for meaningful action to help the recovery of the southern resident killer whale population off B.C.'s coast.

Raincoast Conservation Foundation released the video today to demand action including closing commercial and recreational chinook salmon fisheries.

Biologist Misty MacDuffee says population viability analysis completed by Raincoast shows that southern resident survival requires more chinook salmon and less noise and disturbance from vessels.

She says low abundance of chinook corresponds to killer whales not getting enough to eat, their survival and birth rates dropping and mortality increasing.
