My understanding is fish stocks are already depleted and will be further devastated by climate change[0]. Human diets in the future will necessarily include much less fish.

"A new analysis, published Thursday in the journal Science, found that the oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago. The researchers also concluded that ocean temperatures have broken records for several straight years."

That is my understanding as well. This study[0] estimate that the worlds oceans have lost 2/3 biomass of predatory fish in the last century.

It's really disturbing.
