I did not attend - others who were there can answer. Discussions I've had would suggest the fishing community needs to address what they believe is a goods day on the river. Either fish counting in numbers, and length caught, or a quality fishing experience catching a few better than average fish. It is my understanding regulations can be customized to fit either objective.
There will be a need to broaden the scope of stakeholder input beyond the floppy hat-wader-fly fishing community. Single hooks and no triple-hooks should be the first step. We also need to be aware of the AEP Fish Conservation and Management Strategy - link attached:
https://www.alberta.ca/fish-conservation-and-management-strategy.aspx
The documents goes into the AEP principals to fishery management. What is of most importance are the guiding principals for consultation and delivery of the program. Recreational fishing is at the top of the agenda and commercial interests ( that includes outfitters and tournaments)) at the bottom. This would suggest that any policy change in the management of the Bow River would protect the interests of the individual angler in preference to guiding and corporate interests.
