This is up for debate. I want my government to protect our fisheries from other countries (as well as our own fishing industry) strip mining them bare until there's nothing but sea floor remaining.

They're not just fisheries for today, they're fisheries and ecological systems for the future, and if unreasonable demands are placed on them (for whatever reason) government is responsible to push back to protect those resources. If this causes food insecurity, the government of those impacted must make efforts to source food supplies elsewhere.
