The purpose of these rule amendments is to modify the Commission’s Marine Life Rule in order to ensure the long-term sustainability of this fishery. These rule amendments were discussed by a Marine Life Workgroup composed of industry representatives over a three year time-frame and taken to public workshops. Language will be added to the rule chapter that will authorize the issuance of Special Activity Licenses for activities that are otherwise prohibited in this rule chapter. Additionally, new fish and invertebrate species would be added to the rule, which would require a marine life endorsement for commercial harvest. These additions are: porcupine fish, spotted burrfish, black brotula, key brotula, yellow stingray, blackbar soldierfish, red mithrax crab, emerald crab, red ridged clinging crab, the snail Lithopoma tectum, all hermit crabs (except land hermits), and nassarius snails. Misspellings in this section will also be corrected. A definition of fork length will be added for the measurement of tangs. The size limits of several fish species will be modified for commercial and recreational harvesters, including establishing maximum size limits for parrotfish and tangs, and widening the slot limit on butterflyfish. The recreational bag limit will be modified to allow no more than 5 of any one species within the 20 organism daily bag limit and create a 2-day possession limit for recreationally harvested organisms. The rule amendment would also establish a vessel maximum limit for dwarf seahorses and emerald crabs, and establish personal possession and vessel possession limits for zoanthid polyps, corallimorph polyps, and scarlet hermit crabs. The amendments will decrease the vessel maximum limit on condylactis anemones and add the snail Lithopoma tectum to the current star snail personal and vessel maximums. The rule would also establish a personal possession limit and vessel possession limit for butterflyfish instead of the current vessel maximum. Tools for the taking of corallimorph and zoanthid polyps will be specified for both recreational and commercial harvest in the amendments. Updates will also be made to existing commercial harvest restriction wording to make it more consistent with the endorsement program. The amendment would also allow the harvest of ornamental sponges north of Egmont Key in the Gulf of Mexico to be taken with a 1 inch amount of substrate beyond the holdfast and a 1 inch thick piece of substrate below the holdfast of the sponge. Taking ornamental sponges with substrate would not be allowed in waters south of Egmont Key. The amendment would modify the requalification criteria for the Marine Life Transferable Dive endorsement to allow live rock landings, because they were allowed for the initial qualification. The regulation regarding the use of quinaldine would be amended so it can only be used with the Marine Life Transferable Dive endorsement and the Marine Life Non-transferable Dive endorsement. Portions of the rule in Rules 68B-42.006 and 68B-42.009, F.A.C., are being removed because they are no longer necessary and outdated references to Marine Patrol and the Department of Environmental Protection will also be amended. The effect of these rule amendments is that more species will be given greater resource protection. Newly-added species will have their potential commercial exploitation reduced by limiting their harvest to only those that possess a marine life endorsement and limit their recreational harvest. The addition of size and bag limits will further reduce their harvest by collectors. Amending the language governing the issuance of Special Activity Licenses will allow holders so permitted under the License to conduct the activities within the Florida Keys National Marine Sanctuary (FKNMS). This is in conjunction with a Memorandum of Understanding that is already in place between the FKNMS and the FWC. The definition of fork length will clarify this measurement technique for fishermen and law enforcement. In addition, specifying the allowable tools for the harvest of corallimorphs and zoanthids will reduce the amount of substrate removed in order to reduce impacts upon the surrounding habitat and aid the enforcement of this rule within the FKNMS. The specification of an allowable substrate amount for ornamental sponges North of Egmont Key will help protect the resource and clarify language for marine life harvesters and law enforcement. Changing the requalification criteria to include live rock sales will make it consistent with the original qualifying criteria. Restricting the use of quinaldine will ensure its use only by endorsement holders permitted to harvest by diving, which was the original intent of the rule. Removing outdated sections, correcting misspellings, and clarifying language regarding commercial harvest restrictions are intended to aid understanding and adherence to the rule chapter.
