The Maritimes region of DFO has regular interactions with officials in the state of Maine. I think one of the issues with lobster is that it is fairly sedentary. The typical interactions with Maine would relate more to discussions around conservation, but as you say, conservation isn't the main issue in this case. I'm not aware of whether there have been any discussions related to dealing with supply, but that doesn't mean they haven't happened.
To reinforce what Kevin said about boat quotas or other mechanisms—changes to season, changes to carapace size or any of the others—because of the health of the stock there isn't a strong conservation argument to be made to implement any of those types of management measures.
It may seem somewhat frustrating, but that's why the department's approach is very much one of working with industry to come to a consensus on a way forward. It's because the interventions that would occur would primarily be focused on the economics side. But it's their industry, and it really needs to be something that they come to us with.
