Sheepshead spawn in February here. You can go out to the shallow water rigs and fill the boat up...all you need is a 1/4oz. jighead and bait shrimp. Last trip we made, caught over 400 and filled 4 ice chests. Made a big donation to the Saltwater Mafia to feed the needy...
with a jighead, you flip it next to the rig leg and just watch it fall....when it stops falling before it hits bottom, set the hook, fish has got it. If the fish feels tension, he will spit out the hook and you miss him.
