Right up until they started getting netted hard the chums were doing very well, same with the pinks.
I don't think anyone here disagrees with you in that habitat does make a difference, it just doesn't make nearly the difference that netting half (or more) of the returning fish does.

Uhh, what? Obviously it does since many other runs aren't nearly as abundant to begin with. Also, I have agreed throughout that netting is a big problem. Salmon runs are dying of a thousands cuts, and most of those cuts ain't small.
