I'm not sure if you're the guy to ask, but I'm sure you're aware of the continuing acidification of the oceans via CO2 absorption. From what I've heard it's highly unpredictable as to how it will actually affect ecosystems, but supposedly some molluscs are already having reproductive issues as their shells tend to dissolve at some point in the growing cycle. The predictions I've read point to a likely oceanic food chain collapse in 15-25 years, not to mention the decrease in fertility that fish seem to be experiencing from higher temperatures.

Is that roughly correct?

I heard whispers of "its too late" in the early 90s, with respect to the top meter of ocean and the biological life cycles there being broken.. yet we had the international CFC ban and that was a success at breaking the Ozone Hole, which made things better.. Let's be eyes-open on every detail, but be aware of the despair aspect too .. "collapse in X-X+10 years" is overwhelming to many ears, and we do not know the future.. hth

Overfishing masks that effects also. There is not reason to think that fish fertility as a global concept would change. Some species would decrease and other increase but jellyfishes would be the real culprits in most cases if you see a big decrease or recruitment when the water is warmer.
