Ya got it Rivrguy except for the size thing. Right now, size of adult salmon in the N Pacific (coho and Chinook especially) is crashing due to food web issues. We have to not only stop killing the salmon out there but their food.

Back when I was working, there were some analyses that said it was the draw fisheries that were killing Yukon Chinook. But, because of the volume of fish taken in the trawls, the by catch was sub-miniscule. It may have been 50% of the run (made up number) but it was like 0.1%, or less, of the landed catch. As we know from selective fisheries, even low by catch numbers can have a huge impact.
