It's a matter of which issues you want to address. Obviously there are several issues, and nothing is perfect.
Right now, from a waste discharge perspective, the federal government has been following on work from the provincial government to characterize and reduce impact from waste discharge. This would be things like feed and feces flying out from net pens, and the same thing with escapes.
I think the federal government is working quite well with the industry. I can't think of any one particular item it would work on that would address a specific issue. I'd almost have to think of a specific issue.
Probably the best thing the federal government can do is establish metrics across the industry so we're actually improving things we can measure.
