Is there any research that has studied to see if there is a link with populations of key predators such as leatherback turtles and sunfish?

I think it is becoming quite clear that jellyfish numbers have skyrocketed in recent times. Fish eat huge amounts of zooplankton, and young jellyfish make up a large proportion of this, and overfishing has left the jellyfish with far fewer predators.
Yes, warming seas will increase numbers of jellyfish, but the swarms we are seeing now are mostly due to the overfishing of fish and other marine animals that eat jellyfish, of that I'm sure.
