Although never abundant off our coast, at least not during my 43 years of fishing, two species we seem to see even less of these days are the Nassau and Yellowfin, Here are the largest we caught of these two species. My Yellowfin weight 32 lbs. My dad was never a good photographer, a little more to the left and both me and the fish would have been left out of the photo. What he lacked as a photographer, he made up for as a fisherman. He got the Nassau which wasn't weighed since it was released, but I estimated its size at about 18 lbs. Both were caught off north Key Largo on different days over 25 years ago.
