Got a question about herring. Last year, I went salmon fishing in Alaska. We were trolling 6"-7" herring on downriggers. I smelled a couple of the frozen herring, and I swear, if a guy had his eyes shut, one would call it a shad. I mean they smelled just the same to me. I cut one and they were oily and seemed tougher than a shad. Question is, anyone use these for channels or blues? I know that one can order them from the internet, and it seems like they may be an alternitave when shad are hard to come by.
