I think the biggest problem is that Sea lions taste horrible. I was told be a tribal member that the best way to describe the taste was to take a chunk of black tar. Throw it in to a barrel of dead fish and let it soak in the rotting fish for a week or two. Then after the tar has soaked up enough of the rotting fish, heat up the tar to make it soft and eat it. Rancid, super chewy fat. Getting enough tribal members to eat it could become a problem.
