As recently as the eighties, and I am sure it is still done along the Louisiana coast somewhere, I would take a 14 ft boat out along the jetties of the ship channel at Cameron, Louisiana. I would head out around midnight and once anchored rig two coleman lanterns about three feet off the water on either side of the boat. Using a rubber tailed jig or spoon, I could fill two igloo ice chests with specks and a few reds by first light. Around a half dozen would go into a small cooler for the freezer and the remainder would be dropped off at a seafood retailer on the way home. Those nights were great fun (except when a crew boat came by too close) and seriously augmented a captain's meager salary.
Those are some awesome Lingcod. Caught my first from the rocks off Big Sur, while in at the Defense Language Institute in Monterey. Just getting to a position from which I could cast was an adventure in itself.
