The problem isn't so much coming up with a specific mechanism to limit fishing. Such a tax would work, as would outright quotas backed by criminal law.
It's to agree and to implement any common strategy in a classic Prisoner's Dilemma, where it's beneficial for every single participant to break any agreement. Another difficulty is that the partners that would agree (governments) are not themselves fishing. Even with the best intentions, not all of them have the means to sufficiently police every operator of a fishing vessel.
The silver lining is that it's an "iterative Prisoner's Dilemma". The "prisoner"'s decision isn't isolated from everything, because others will respond in the next round. The issue can also be combined with others, tying, for example, trade agreements to sufficient cooperation (c.f. Brexit).
But the sheer number of participants alone makes it a slow slog. Just look at the problems OPEC has, even though that group is a lot smaller and the activity in question is far easier to control.
- acd 6y agoInteresting comment. In single shot prisoners dilemma the best strategy for both players are too cooperate remain silent. In iterative prisoners dilemma the best strategy are Tit for tat strategy. The strategy should be nice not defect before opponent, Retaliating, forging and non envious. How do you make a tit for tat fishing strategy? Reference link to prisoners dilemma. https://en.wikipedia.org/wiki/Prisoner%27s_dilemma https://en.wikipedia.org/wiki/Prisoner%27s_dilemma
- IfOnlyYouKnew 6y agoNo, in single-shot PD betrayal is the dominant strategy, as your link shows. It's better if your opponent also betrays, and its better if they stay silent (the whistleblower scenario). See that wikipedia link if in doubt.
- oehtXRwMkIs 6y agoI think the tragedy of the commons is a more appropriate analogy rather than the prisoner's dilemma.
