Hi guys I'm new to this site,but I was thinking,why don't they do to seals as they do to the garbage bears aclimatized to humans,especially in the rivers.Tag em and bring them to a new area, if they return,they will never be trained.then they would have to be destroyed.just like the bears,don't feed them,treat them as the wild animals they are.One small step could start a proper maintenance program.start at saving 10 or 20 thousand fish at a time.
