Jack mackerel, rich in oily protein, is manna to a hungry planet, a staple in Africa. Elsewhere, people eat it unaware; much of it is reduced to feed for aquaculture and pigs. It can take more than five kilograms, more than 11 pounds, of jack mackerel to raise a single kilogram of farmed salmon.
Stocks have dropped from an estimated 30 million metric tons to less than a tenth of that in two decades. The worlds largest trawlers, after depleting other oceans, now head south toward the edge of Antarctica to compete for what is left.
An eight-country investigation of the fishing industry in the southern Pacific by the International Consortium of Investigative Journalists shows how the fate of the jack mackerel may foretell the progressive collapse of fish stocks in all oceans.

(Not picking on Kiwis - just an example...)

(25,966 posts)You're a fisherman, and you look around and see that either you get it, or your competitors will.
"Saving the fish" isn't even an option on the table.

(36,266 posts)Interestingly, many "primitive" cultures figure out for themselves that overharvesting is the problem, and establish quotes which are enforced by the whole society. It's trying to keep the "outsiders" -- esp. industrial fishing vessels -- out that is the real challenge.
Worth noting that the main reason the Somalis turned to piracy is that their traditional fishing grounds were being depleted by factory ships (I'm looking at you, Japan). Similar things are happening in the Phillipines now.

But this is why I won't eat them.
It's a very sad thing that someone else will.

(21,088 posts)Reports like this merely strengthen that conviction.
