The only thing surprising to me about this video is the salmon in the ditch. The snagging is completely normal on the skoke. It's also normal to just open the bellies of the chum and take the eggs, then leave the rest to rot. I assume that's what is going to happen to the ditch full of salmon. I don't know if that's the skoke or not I don't recognize that spot but I haven't fished it for probably 8 years.
