I'm waaaaay out of my waters here, but if I had to take a wild guess: over fishing, changing of chemistry of the oceans do to climate change and yeah rising of median temperature (as we can all feel) of the world .. in summary: my guess is human activity.
The higher the temperature the less oxygen in the water
This is what I meant, and in a broader sense, we just leave it at: scientist are baffled and do not know the answer when I think we all know damn well, almost sure it has something to do with human activity and the disruption it causes in nature.
