What should governments and conservationists effectively do to stop the overrfishing of blue fin tuna?

Question

The taste for eating raw fish, a Japanese custom, has spread to other parts of the world in recent years. If the Chinese market continues to grow, that will very likely be the end of blue fin tuna stock. For the time being. Japan, remains the main consumer of bluefin tuna. Around 80 to 85 percent of bluefin tuna caught in the Mediterranean is exported to Japan. The potentiallity is there to place a moratorium on blue fin tuna fishing, but governing bodies (decision makers) apparently lack the political will, while the bluefin tuna industry fishes itself to death.

Answer 1

Instead of forcing other people to do what you think is best. Why don't you just stop eating fish.

Answer 2

Government is not the magic answer. WE have enough regs111

Answer 3

Very large fish are an obvious easy target, and you are right that they are being fished too heavily for their long term survival.

But there is a secondary problem too. Their food stock is scarce. Even taking a number that would have been regarded as a sustainable catch a few decades ago appears to be cutting down on population because the blue fin are not growing as fast, and are not surviving to maturity.

What this means is that there may not be any level of blue fin harvest that can be sustainable, and we may not be able to sustain populations even without any blue fin harvest.

It could be that we have to go back to the species they mostly eat, and cut back on harvesting them, or deal with any problems that are causing the collapse of those food species in order to retain blue fin.

Is there a value in a moratorium? Only if they can feed themselves.
