I’m with #7 but the authorities could make a handsome profit.
Corral a bunch of the seals and charge $100 per person who wants swing a bat at their heads.
No pushing or shoving, please!
Have a lottery to kill these damn rats with flippers.
Anyone wanting a chance to kill the seals pays $100 for each lottery ticket.
Then, the chosen ones have to come up with a thousand $’s for the actual permit to kill these vermin with flippers.
The winners can have the meat/fur, or donate it to Indian Tribes or to the street people.
Do this on every river where steelhead and salmon migrate, and in a few years we will be over run with salmon and steelhead.
