You should have no problems at all finding King and Spanish Macs around then, if you go out farther its a good month for Blackfin Tuna and maybe some Dolphin, that's a great time to fishs all in all, I like April and May the best for spring time fishing in the Tampa Bay area. Grouper should be bitting to.

Kingfish can be found from the Skyway bridge to hard bottom the beaches, hard bottom in any depth for that matter and every artificial should hold some, look for birds and sky rocketing fish, you can also drag the shipping channel, if you are looking for eating fare, target the smaller ones (less mercury) use king spoons for these and troll 5-7MPH, if you want large ones use Live baits slow trolled or anchor up and chum.
