Like Harv said, you must be talking about a different fish if you find them in fresh water. You can see what we're talking about <A target="_blank" HREF=http://www.landbigfish.com/fish/fish.cfm?ID=26>here</A>. Incidentally, I agree with nearly everything on that page, except he prefers a 7' rod with 50# line and I used an 8' rod with 30# line. All my fishing for sheepshead has been around Port Aransas, TX, and we either use live shrimp or fiddler craps for bait, let it down right alongside pier pilings, along the rocks on the jetties, or at the bottom over rocky bottom areas. Heavy bodied fish that pull hard; lots of fun. Great bait thieves; if you catch one for every 5 baits you're probably doing good.
And when I first started going to Port Aransas almost 30 years ago, almost no one fished for sheepshead, they were not considered a game fish so there were no restrictions, etc. And now we have a 12" minimum size and 5 fish bag limit./w3tcompact/icons/frown.gif Dad and I used to have no problem putting 20-40 a day in the freezer and now you're lucky to catch your 5 fish limit. Biggest one I've caught was 7.5# and Dad's biggest was 8.5#.
