The chum snagging video from Alaska certainly looks disturbing based upon our local standards and laws. But if you read the youtube poster's comments, he defends the practiice and states that what he is doing is legal and that he is killing unwanted surplus "ranched" hatchery chum for bait. Anything wrong with killing a chum just for bait here in the lower mainland?
The same thing for the "spoonbill snagging" videos. I have never seen a spoonbill before and watching videos of guys snagging them with multiple 3/0 treble hooks is kind of shocking. But it seems that is legal and the acceptable standard for fishing for spoonbills.
Same thing with that documentary "The Cove". The sight of killing dolphins made me want to vomit. But if you step back and view it as a harvest, how is the harvesting of dolphin different from the harvesting of salmon, tuna or turbot or buffalo in the past. If the species is being harvested to the point of extinction, then it should be stopped. But if it is regulated and sustainable, then why not? Is killing a wild salmon less wrong than killing a dolphin because a salmon was never given a name and its own tv series?
Not saying that I agree with any of the above or that I would do it, but trying to see the point of view of the other guy.
