Get Prepared for Low-Impact Lobstering

Lobster season is one of the busiest times in the Florida Keys, as thousands of visitors and residents hit the waters in search of one of their favorite delicacies, the Florida spiny lobster. With smart choices, you can lower your impact on sensitive coral reefs, plus other natural resources, that you are here to enjoy.

Start by learning lobster regulations for the Florida Keys. You'll find thsese in the Monroe County lobster brochure. Knowing the fishery rules will help ensure sustainable harvests into the future. Next, be safe on the water and practice respect not only for fellow boaters and divers, but also the coral reefs and habitats that lobsters call home.

To catch lobster, you must:

  • hold a valid Florida saltwater fishing license and lobster permit to harvest lobster;
  • release all female lobsters bearing eggs (usually bright orange) on the underside of their carapace, regardless of size; and,
  • do not harvest lobster without first using a lobster gauge to confirm its carapace is greater than three inches long.

For your own safety, and the safety of those with you, you should also:

  • check your vessel's safety gear and familiarize yourself with the local waters where you plan to boat
  • follow good reef etiquette. Absolutely NO touching or bumping coral!
  • service your dive gear, practice your dive skills, and plan your dives.

Florida Spiny Lobster Fun Facts

The Florida spiny lobster, Panulirus argus, is also known locally as crawfish, "bugs", or langosta (Spanish). Lobster bodies have two main segments: its head section, covered by a carapace, and an abdomen, or tail section. Unlike its northern cousin, the American lobster, it lacks large claws. The "spiny" in its name refers to a set of forward curving hard spines that cover its hard outer shell (the exoskeleton). Its colors vary from whitish to dark red-orange, and two large cream colored spots at the top of the second tail segment are an identifying feature of this species. Often, the first feature that you will spot in the water are two long, thick, antennae with spines that emerge below its eyes. Below these are two small sensory antennules.

Common in Florida Keys and found from Brazil to North Carolina, the spiny lobster lives in rock, coral reefs, seagrass beds and hardbottom habitats through the tropical and subtropical waters of the Caribbean, Gulf of Mexico, and Atlantic Ocean. It feeds on crabs, shrimp, snails, clams, and other crustaceans and mollusks. Lobsters tend to congregate in crevices to avoid their predators, which include the common octopus, loggerhead turtle, blue crab, nurse shark, Southern stingray, and reef fishes such as grouper, snapper, and triggerfish.

Reproduction

Lobster reach maturity and start reproducing at three years of age. The females carry the eggs on their abdomen (underside of the tail) where they are fertilized externally. Spawning takes place between March and August in waters that are 73ยบ F or warmer. Fertilized eggs incubate for three weeks, during which their orange color deepens to dark brown. Newly hatched lobsters are small larvae that drift thousands of miles on ocean currents for the first six to nine months. Once settled into a suitable habitat, the larva grows and molts into a juvenile. Although large female lobsters can spawn two to three times a year and produce up to a million eggs, as few as one egg, on average, might survive to adulthood.

Growth Rate

It takes approximately three years for a lobster carapace to reach three inches. They can grow to over 15 lbs. and live more than 20 years. Male lobsters typically grow faster than females.
