Can I ask a stupid question in earnest? Is it bad for them to die out? Is the fear that if we lose 90% of this life that there will be complete collapse of the worlds ecosystem?

Maybe a better question would be: where can I find more information on the consequences of this?

AFAIK 50-80% of our oxygen comes from Phytoplankton in the ocean.

I believe that when a fish population declines by 80–90% it never recovers, that's it. Even if you leave them alone. It happened to cod in Newfoundland.

The excellent 2009 documentary "The End of the Line" was the first place I heard discuss catastrophic fish population crashes, and it covers this dramatic topic and its very serious implications in detail. It also talks about the mind-boggling, almost unbelievable scale at which modern fishing vessels such as supertrawlers operate.

Frankly, I was horrified by what I learned about modern fishing watching this movie.
