Jim,
Water temp now is cold ,Should be in mid 70'S,March is a toss up,can be flat,can be choppy,for the last 3 days the winds here have been at 15 to 20 MPH and seas 4 to 6 foot.Some friends have gone spearfishing in early January,they have told me water very cold and have gotten cramps.
I have been watching the Florida Fishing Report for the last few Thursday's and fishing in the Keys has been very good,sails in 140 to 200 ft of water around Davis and Conch reefs,grouper in 60 to 70 ft on the reefs.
I have never really been a rod and reel guy,so my fishing experience is limited to kids catching grunts and the likes.I only spear,usually for Hogs,grouper and other fish which can eat (never take more than limit) and no under sized fish.
dont know of any places which can spear in Big Pine,there is another member here who lives in Marathon,I bet he knows.
Over the last few years there have been Reefs that have been designated as protected and therefore no spearing allowed.
Jim,I would be very glad to go with you but as I told Larry,work is a problem now,I may have only one day to go down to the Keys and I would like to do that so that I can meet all of you,I dont know if during daytime or will have to be at night and have dinner with all.But will definitely go down to Big Pine Key.
Robert
