I talked with a researcher who is involved in a huge study in BC. They are looking into a variety of angling issues in about 800 lakes. They are looking at angling methods, regulations, fish growth, angler density and a number of other issues. They are using aerial sampling methods to watch boat density and distribution as well as using webcams to observe angling effort. One thing he said was that BC will switching their rainbow stocking completely to All Female Triploids so there won't be any males to worry about.
It would be great to see a bit more research funding directed toward Alberta's fisheries. How much Alberta's fisheries are valued is very evident by the lack of money made available to study them.
