Slot sizes won't work in Alberta as nothing seems to make it through the slot
About 800 lakes in Alberta support natural game fish populations, and another 250 to 300 are stocked regularly with game fish. Assuming all the lakes supporting game fish are equally accessible to the estimated 350,000 Alberta anglers, this would amount to a ratio of about 320 anglers per lake.
Compared to other provinces, angling use is very high on many of Alberta’s lakes. To compare, Saskatchewan’s 94,000 lakes, Manitoba’s 110,000 lakes and Ontario’s 250,000 lakes each have a ratio of only 2 or 3 anglers per lake.
