like I was saying, many people would like us to abandon this large source of protein even though sustainable fisheries are possible.
Look at the fisheries in New Zealand or Alaska for examples of very well managed fisheries.
In many developing countries it's not a tragedy of the commons problem, it's a structure/stability problem. How can you ever have managed fisheries without political stability, or with stability but rampant corruption?
How can you have political stability without economic stability and food? It's a chicken and an egg problem.
Hello from New Zealand! I beg to differ about "well managed fisheries". NZ has regulatory capture, massive bycatch problems, and some species are near to collapse the way that orange roughy collapsed. The government talks it up as a sterling example of property rights, but the results are atrocious. It's a faith-based claim of success.

Bans seem to work better for charismatic animals. We spend about $10,000 per year per tiger on conservation efforts [1]. Meanwhile, marine protected areas [2], of which some are no-fish no-catch, are notoriously under-enforced [3]. Which kind of makes sense given nobody is directly incentivized to pay for it.
