The sea otter is another example of over-protection. They have rebounded with a vengeance in Southeast and wreak havoc with crab populations and have all but destroyed abalone.
They should be managed by allowing residents the opportunity to obtain a tag. Fish and Game has even bounced around the idea of a bounty. However, harvest is limited to Alaska Natives. And they aren't making a dent in the problem. Even a limited draw permit would be helpful in managing these fishery destroying marauders. Plus, give someone else the pleasure of owning a fine pelt.
