Most of our southern reservoirs have great fishing without a stocking program. Natural reproduction is definetly the way to go. Stocking is extremely expensive for how many fish will survive to suitable size (if theres no fish there anyway its probably due to the fact habitat sucks, stocking will still not make it a great fishery).
A bass fishery would work in some of the lakes but again, would you rather catch pike and walleye or itty bitty bass? It would cost a lot and the chances of bass negatively affecting native fish stocks in our rivers is high ( i would be in favor of triploid fish in closed systems as a put and take fishery, i have seen sunfish take over a Southern Alberta Lake, not neccesarily great for other species). There are many reasons management occurs like it does. If you want to fish for food there are put and take fisheries for trout accross the province which serve this purpose. For the number of lakes we have and number of anglers its still a surprise we can keep many fish at all.
If walleye stocking is needed it should be a zero limit anyway as other management objectives have failed so it will not help fill your fry pan. For the money and resources our provincial biologists are given, they are doing a great job. Most people do not realize how complicated fishery management is in this province. Don't let the number of walleye being stocked fool you, very very few will survive from the size they're stocked at. Good fishing!!
