Just out of Yakutat, Alaska we fish a bridge over a tidal saltwater estuary....some of you may know of it....the Anchow bridge. When the tide is running either way the silvers cruise in and out of the estuary like fleets of submarines in full view of us. We commonly use mooching leads and herring (either plug-cut or whole) to "troll" off the bridge. When the tide slackens a bit we have used bobbers to keep the herring off the bottom. It is a very effective and fun way to sight-fish these aggressive biters. Also a good way to learn about their biting patterns. If you try to set the hook on one with a herring in it's mouth most often the fish just opens its mouth and releases the bait. But if you wait until the fish turns away that critter is doomed to the BBQ for sure.
