Trip Summary

As of July 5th the water temperature at the Mayport inlet hovered between 72-75. This is quite a drastic difference compared to the average temperature of 85 degrees. The fish have not wanted to bite out that way so intead Ive been taking clients to go do some back water fishing in the Intracoastal Waterway. By the time we run away from the inlet we are finding water temperatures up to 80 degrees. This little bit of warmer water definitely has the more active fish. We used a combonation of Shrimp, mud minnows, and fiddler crabs to work shallow and deep spots between 2ft and 20ft. We were able to bring home a couple of delicious flounder and a sheepshead for dinner. Although the keepers werent biting well we managed to stay busy catching and releasing several other species including black drum, Seatrout, catfish, and jack crevalle. As the new week begins I am hoping the water temps warm back up and the beaches/inlet fishing will come back to life. Tarpon fishing is on the brain and I am looking forward to their return.
