I guess they're paying for killing so many sea turtles with these same nets as a bi-catch. Sea turtles are to jelly fish as tortoises are to cactus, able to exploit food sources that few other critters can.
Mama nature's doing a big "I told you so..."

But I'm just amazed that there is one thing they won't eat at a sushi bar.
