John Neilson, a fisheries biologist at B.C.B次元官网网址檚 Simon Fraser University, says itB次元官网网址檚 the most extensive survey of chinook numbers the committee has ever done.

He says the declines are likely due to something happening to the salmon after they migrate to the ocean.

He says the federal government needs to protect habitat for the stocks that are in the worst shape.
