About the gill netting ... I am VERY surprised to hear of so few fish netted. But then again, maybe that is typical for gill netting up there. And so few over 10 lbs. I find that disappointing. Again, probably just my lack of knowledge regarding gill netting.

No one has said anything about the objectives of the gill netting. Biologists are able to somewhat target specfic fish by using different sized mesh in gill nets. The larger the mesh, the larger the fish that will be caught in those nets. Many times (again, I don't know what the objectives of this netting were) biologists do not want to catch the larger fish, so they use a smaller mesh. Usually, a larger fish will hit the net, and simpley swim away from it. Sometimes, they are still caught (teeth, fins, etc.).
Also, location and depth play a big part in what fish are caught in the nets. Mortality can also be controled be lenght of time the net is set for. Over-night nets typically kill the majority of the caught fish. At Fishlake, the October netting is done at night and the nets are only set for 30 minutes. Very little mortality takes place with those nets.
