What, it's only 400 tons of Jack Mackerel in one scoop, and surely it will all be used efficiently with no waste.
But that turtle, or maybe terrapin I guess, didn't get caught up in a net as collateral damage of commercial fishing, some bastard hooked him and instead of hauling him in and at least retrieve the line even if he/she couldn't get the hook out, couldn't be bothered so just cut the line to foul the turtle and anything near it. He/she callously killed the turtle.
Make it manslaughter (turtleslaughter) if a hurricane, Iranian torpedo boat, or Monstro the Whale, were bearing down on his/her dingy.
