Don Anderson: One of the references in the article is well worth a read:
Arlinghaus et al,. Understanding the complexity of catch and release in recreational fishing.

It is the most exhaustive and detailed article I have ever read on C&R.
Unfortunately AEP fishery biologists have little impact on the remediation of habitat loss as a bigger picture initiative.
Invasive species, carp, brook trout (?), rainbow trout (?), brown trout (?) where does it stop. If the goal is protect only endangered native fish species, our recreational trout fishery is doomed!
Whirling Disease is here to stay and time will tell just what long term impact it will have on the Alberta fishery.
So what is left?
The following link document review by University of Calgary researcher, John Post for 2002 give a depressing account of the Alberta fishery at that time. The analysis is still true today. We need to accept the reality that the Alberta sports fishery is unsustainable without further angling restrictions. At least this is my take.
