I'm quite certain they do, of course that is denied by the powers to be. But it is interesting how the East Coast Vancouver Island Streams have virtually no fish and the glut of fish farms is on their path to the open ocean...
There are likely a plethora of problems they face, certainly ocean conditions will be primary amongst them. We just don't know. Salmon survival rates are way up, yet steelhead survival rates are way down, what is the difference? We don't know.
Oregon survival rates for steelhead are up, so it undoubtedly has something to do with the ocean conditions that the Greater Georgia Basin steelhead face. So in the face of this uncertainty it becomes paramount that we reduce the threats that we know about; commercial interception, de-watering of rearing areas, fish farm/sea lice issues etc.
