I just came back from my three week vacation in Big Pine Key. The weather wasn't the best but it is better than -20 with snow. I was shark fishing at Bahia Honda bridge in 58.5 degree water for over a week. I got two sharpnose sharks and that was it. That's chumming and with multiple tuna heads/carcasses out at a time. That was the first year I never saw a Bull shark at Bahia Honda bridge. The water was so cold I was getting redfish fishing from shore, a couple of snook (though they were very slow), cero mackerel and some barracudas. The days I did get out on a boat, we were often at a bridge getting out limit of nice mangroves.
By biggest fish was a 5.5 foot silky shark, I got him in 250 of water on a wreck. The fishing wasn't what I had hoped for but I learned that when it comes to fishing, you can't force what happens. If there are no sharks there, you can't change it.

Silky shark (my first) 5.5 feet
King mack 50.5 inches-30.4 pounds
41 inches
Redfish (my first) 30.5 inches

Little tunny (biggest) 35 inches (smallest) 25 inches
Snook 28 inches
