Greater AJ is not closed. The closure ended when the calendar year changed and we began a new year's quota.
You just need a FL saltwater license for the number of days you will be hunting. So if its just a weekend you can get a cheaper version instead of the whole year license. The regs change over to Federal waters at 9nm in the Gulf and 3nm in the Atlantic. Note that regs tend to be different from the Atlantic to the Gulf. For example Grouper is closed now in the Atlantic waters but not in the Gulf. There are no prohibitions on any type of speargun although powerheads are illegal until you are out of state waters and passed the "stressed area" in federal waters. Florida is a big state, in the Gulf you'll need a charter to get to the fish as there is very little shorediving available. East Coast is alittle different.
Spearing is defined as "the catching or taking of a fish by bow hunting, gigging, spearfishing, or by any device used to capture a fish by piercing its body. Spearing does not include the catching or taking of a fish by a hook with hook and line gear or by snagging (snatch hooking)."
Spearfishing is defined as "the catching or taking of a fish through the instrumentality of a hand or mechanically propelled, single or multi-pronged spear or lance, barbed or barbless, operated by a person swimming at or below the surface of the water."
The use of powerheads, bangsticks, and rebreathers remains prohibited. The following is a list of species that are prohibited for harvest by spearing. Any other species not listed that are managed by the Commission, and those species not managed by the Commission, may be harvested by spearing.
* Billfish (all species)

You may NOT spearfish (excluding bowhunting and gigging) as described below:
* Spearfishing of marine and freshwater species in freshwater is prohibited. Possession of a spear gun in or on freshwater is also prohibited.
* Within 100 yards of a public swimming beach, any commercial or public fishing pier, or any part of a bridge from which public fishing is allowed.
* Within 100 feet of any part of a jetty that is above the surface of the sea – except for the last 500 yards of a jetty that extends more than 1,500 yards from the shoreline.
* In Collier County and in Monroe County from Long Key north to the Dade County line.
* For any fish for which spearing is expressly prohibited by law (listed above).
* In any body of water under the jurisdiction of the Environmental Protection, Recreation and Parks. (Possession of spearfishing equipment is prohibited in these areas, unless it is unloaded and properly stored.)
Fishermen who catch and/or sell fish harvested by spearing are subject to the same rules and limitations that other anglers in the state are required to follow.
