The pair restarted their work in Massachusetts with about 400 brook trout reared for up to eight months in tanks. The scientists kept some of the fish in waters set at 59 degrees Fahrenheit while others at 68 degrees Fahrenheit. All were fed the same diet.
By the end of the experiment, the difference was stark. The trout raised in warmer waters were on average less than half the size as the other fish.
The other day I read the history of the Somalian pirates. Basically corps from wealthy nations like China stole all their fish with bottom trawling, and after the initial failure of their state they had nobody to enforce the rules. They tried chasing off the illegal fishers themselves, but were declared pirates because of that. Then they went “if we are pirates anyway, we might as well”, and then we get to the part when the US went in to shoot up their capital and made a movie about it.
