Fishing Jetty Park off the rocks. I hook up on what feels like a pretty nice fish. Start to reel it in with a pretty good fight then just dead weight. Get the fish in and it is ½ of a Spanish Mackerel probably about 16 inches when whole. The fish is severed cleanly in two (see picture). As clean a cut as a butcher would make. My guess, a shark helped himself to a half of my catch.????????
