Waitrose to suspend mackerel sales due to overfishing concerns

A pretty big move. For context there have been concerns about the overfishing of mackerel in the north sea for a number of years (after a successful recovery of the stocks in the 2000s and 2010s) due to the relevant countries not agreeing a shared quota properly. I am usually against the idea that it is on consumers to avoid eating overfished fish as the situation is usually complicated in terms of knowing exactly what stocks and fishing methods are sustainable, and really only government fisheries policies can prevent overfishing. But when you have whole supermarket chains boycotting it then you might see industrial fishers and governments forced into more effective action. I will personally probably pause eating mackerel from now on as the situation is so blatantly unsustainable across the board that I can't do it in good conscience.
