If we proactively implement effective fisheries management and limit global temperature rise, the world's oceans still have the potential to be significantly more plentiful in the future than today, despite climate change. This finding is among several that appear in a first-of-its kind study, "Improved fisheries management could offset many negative effects of climate change," that appears today in the American Association for the Advancement of Sciences' journal Science Advances.
"The expected global effects of climate change on our oceans are broadly negative," said Steve Gaines, the study's lead author and dean of UC Santa Barbara's Bren School of Environmental Science & Management, "but we still have the fortunate opportunity to turn the tide and create a more bountiful future."
The study finds that with concerted and adaptive responses to climate change, the world's oceans could actually create more abundant fish populations, more food for human consumption and more profit for fishermen despite the negative impacts of climate change. Conversely, the study cautions, inaction on fisheries management and climate change will mean even more dramatic losses of fish and the benefits they provide to people.

There absolutely is, you're simply narrowing your scope of "current warming trend" so tight that it becomes immeasurable and also irrelevant on any time scale that could show a useful picture.
The loss of one species of fish is irrelevant to the planet, unless you happen to enjoy catching or eating that specific species above all others. We're not talking survival of every species of fish, we're talking about survival of fish in general.

I stand corrected, there appears to be evidence of rapid (over ~10 a) warming, for instance ~10 °C at the end of the Younger Dryas (YD, ~12 ka ago) (e.g., Grachev and Severinghaus, 2005 [doi.org]). With "current warming trend" I meant the warming especially over the last decades; apparently a bit less and slower than the event at the end of the Younger Dryas.
The following is not directly relevant for your point, but I want to avoid wrong, or overly broad, interpretation of the above. Recent climate change (like the temperature increase since 1970 or so) is unprecedented (IPCC, AR5). More concretely, the global average surface temperature is probably higher than it ever was over the last 20 ka. We don't know if this recent observed change could trigger something more even more rapid (like at the end of the Younger Dryas—if only because we are not sure what the mechanism was). We don't know about all self-reinforcing feedbacks, and of those that are known in principle it's often not clear if there would be compensating mechanisms in time.
Yes, OK. The take-home message of this and related papers seems to be that better fishing management would yield higher fish yields. Moreover, climate change, and in particular anthropogenic, would need somewhat adjusted mangement in different areas. I think that's it. In the paper they are not arguing that "it's because climate change is going to wipe out all the fish".

Right, and like I said, I'm absolutely for thoughtful wildlife management making there more fish for me to catch. I'm just against hysteria and outright lies in the pursuit of such.
