Wouldn't there also be more different fish now especially in places that used to be covered by ice? Sure, some species might die off but you might get more new species as well. Some new fish perhaps that is good at living in lower oxygen concentration. Also, the fish that lived in the tropics can move to subtropics and so on.
I see it as more of a change that's not really bad or good. As Joe Carlin once said, the Earth will be fine.
