@ Lee - I was speaking about the fisheries industry as a whole, not just the salmon. They use seines, or gill-nets for salmon fishing, yes. And I think you are confusing trawlers with trollers. Trawlers are not in the least way sustainable. Trollers were fairly sustainable. Also called long-liners. Deep water trawlers scrape the ocean floors and drag up everything with it. Horrible things that can cause extensive damage to sensitive ecosystems such as the glass sponge reefs near Haida Gwaii.
@ Steven - Chatting with my boss this morning it is clear that DFO is in the business of managing a fishery, and not the fish. I don't believe there is much truth to the argument that there will be losses to salmon by there being too many. Salmon corpses are vital parts of the ecosystem as it is, and provide nutrients not just to the streams, but to the adjacent forests. Salmon carcasses aren't likely to be smothering the eggs either, as they will get washed off to the sides of the rivers, and caught up in branches and other woody debris, where they will fertilize the stream for the next generation of salmon. Bears, and in areas where they eat them, wolves, will thrive off the abundance of salmon and the ecosystem will balance things out. There is no waste. There were fears last year that the bears would suffer over the devastating returns that we had. Maybe this year they will have a good year and produce more offspring over the winter if they fatten up enough this fall. I'm sure the bear watching tourism folks will be enjoying this.
Perhaps there could be salmon redds being dug up, but I doubt that there will be a total collapse because of "too many" salmon returning. What is too many, anyhow? Isn't this what we wanted? DFO is only responding to the pressure by the fishermen to allow more harvest, and this is an easy excuse to do so. My only hope is that there hasn't been a mistake in the calculations.
