Steelhead are not a targeted species but when you fish with gill net you get "incidental" catch of non target species. This catch shows up in U.S. fish counters as "Canadian Steelhead/Rainbow Trout". It's not a regular happening but I do see it here in Mi. stores. Michigan plants about 60,000 in the Huron River and we get a fairly good return. I know Ohio plants a lot, not sure about Pennsylvania or N.Y. Canada has in the past, but I don't think they are now. As far as possibly doing something about it....forget it. Any ***** you would have has to go through the U.S. State Department, and they won't even listen to it.
The thing I don't understand is that there is way more money for local merchants and the Canadian Gov. in sport fishing than there will ever be in commercial fishing. Once again, follow the money.
