Florida Keys

The Keys backcountry holds miles of turtle grass flats where you can see the fish before you cast. Tailing bonefish pushing water across a white sand flat. A string of permit shadows drifting over a pothole. A dark torpedo shape that turns out to be a 120-pound tarpon laid up in 18 inches of water. This is what people come here for.

The best flats fishing happens on the Atlantic side from Islamorada south. The Content Keys, Bahia Honda, and the Marquesas Islands produce consistently for bonefish and permit. Wade or pole a skiff - either way, you need stealth, a good push pole, and polarized lenses that cut the glare. Amber or vermilion lenses work best in normal light. Switch to yellow for overcast or low-light conditions.

Bonefish in the Keys can reach 12 pounds or more, with verified catches of 9.5 and 12 pounds. That is big for a fish that typically tops out around 10. Research from the Bonefish and Tarpon Trust shows that 70% of tagged bonefish are recaptured within 1 kilometer of their original tagging location - they rarely leave their home flats outside of spawning season. When they do spawn, they form aggregations of thousands and dive to depths of 450 feet (13 times the atmospheric pressure of the flats) to release eggs and sperm. Genetic studies confirmed that bonefish larvae spawned as far away as Belize and Mexico can settle in the Florida Keys.

The population has rebounded significantly since 2010. Daily catch rates went from 4-5 fish to 20-30 fish per day on guided trips. Each individual bonefish is estimated to generate roughly $75,000 in economic value over its lifetime through guided fishing tourism - which is why catch-and-release is not just ethical here, it is economic policy.

Disable your depth finder when sight fishing. The clicking sound it emits underwater spooks bonefish. Kill the aerated livewell too. These fish feel everything.

The Florida state record tarpon weighed 243 pounds, caught in Key West in 1975. A near-record specimen measured 86 inches long with a 44-inch girth at 238 pounds. Keys tarpon commonly run 100-130 pounds, and Marathon schools regularly produce fish over 100. These are not novelty catches. This is the baseline.

Tarpon are active in Keys channels from February through July, with April and May the peak months for fish over 100 pounds. Marathon sees two distinct congregation windows: March through June and September through November. The three hours before sunset through after dark is the most productive daily window. Outgoing tide is preferred. Fish moving into the current are far more likely to eat - tarpon swimming with the current ("grey-hounding") generally refuse bait unless you lead them significantly.

Most effective depth in the Keys is 4 to 20 feet. When anchoring, position up-current of a deep hole or channel bend, about 50 yards away. Current speeds in Key West Harbor during tarpon season run 1.5 to 2 knots - enough to sweep a live crab bait naturally through the strike zone.

Live crabs are the preferred bait over live finfish for one simple reason: crabs don't attract barracuda. Use the suspended crab technique - stop your drift every 30 seconds, let the crab rise to the surface, then free-spool 30 seconds to simulate natural swimming. Pass crabs and blue crabs both work. For artificials, chartreuse and white fly patterns are proven producers.

A word on the crowd: during peak season, 44 or more boats can fish the same area simultaneously. The Keys tarpon fishery is not wilderness fishing. It is world-class fishing with world-class company. Book your guide early and respect the rotation.

Tarpon have vision approximately 5,000 times stronger than humans and possess olfactory glands on the side of their heads. They can detect chum from a distance. They are prodigious leapers - fish in the 25-45 pound range jump more frequently than larger migratory tarpon. Fights on giant fish can exceed two hours. When a tarpon does not jump, it fights to exhaustion - a different and more dangerous battle for the fish.

Every bridge in the Keys is a fish magnet. The Seven Mile Bridge, Bahia Honda Bridge, and Channel Five produce tarpon, snook, and snapper after dark. The strike zone is the shadow line where light meets darkness. Drop live pilchards, pinfish, or crabs downcurrent and hold on.

The biggest tarpon in the Keys are caught within casting distance of the road. Bridge tarpon fishing is a drift fishery - position up-current and let the tide work your bait through the strike zone. Snook stack in the mangrove-lined moats around bridge abutments and are most productive from 30 minutes before sunset through a few hours after dark.

Snook in the Keys and Ten Thousand Islands spawn during full moons from May through August. Large specimens migrate into the Everglades backcountry in November and December. Night fishing with heavy jigs is the primary method for giants. Use a 7-8 foot rod with 20-40 pound braid and 60-80 pound fluorocarbon leader for bite-off and abrasion resistance around structure.

Yellowtail snapper fishing at the bridges and reef is outstanding in 30-35 feet of water using 12-pound mono and chum. Cero mackerel mix in regularly. Spanish mackerel run close to the Yacht Channel boundary. This is not glamorous fishing, but it fills coolers and feeds families.

Behind the Keys, Florida Bay and the Everglades backcountry hold a different fishery entirely. Mangrove islands on the flats are circumscribed by deeper moats that harbor snook and tarpon. The Ten Thousand Islands stretch from Everglades City south, offering some of the best snook fishing in the state - fish to 45-46 inches holding in the shadows of rock piles and dead wood left by Hurricane Wilma.

Juvenile tarpon hold where small inland creeks empty into larger bays. The Tamiami Trail canals connected to saltwater hold both juvenile tarpon and snook. Resident Everglades tarpon arrive from the Keys around mid-March and stay through summer into November, feeding near the outer edges of rivers among red mangroves. Early morning is topwater time in the Everglades - first hour after sunrise produces the best surface action.

Skip lures under dock pilings and mangrove roots to cover territory. In clear shallow water, avoid paddletails and topwater (too much vibration) - use jerk shads and artificial shrimp instead. DOA Glow Shrimp is effective in dock environments. White-colored jerk shads work best in clear water. For snook, a 30-pound fluorocarbon leader is the minimum - their gill plates will cut anything lighter.

The Keys fishery is healthy because people take conservation seriously. Here are the rules that matter most.

Tarpon: Fish over 40 inches cannot be removed from the water in Florida. Circle hooks are mandatory. Fish under 130 pounds can be brought in the boat to unhook; larger fish must stay in the water. Handle tarpon with wet hands. Support the fish horizontally. Never gill or gaff a tarpon.

Permit: All caught permit must be released immediately in Islamorada and Monroe County. Florida harvest is closed April through June statewide. Even outside the closed season, most Keys anglers practice catch-and-release.

Bonefish: Catch-and-release in Florida. The Bonefish and Tarpon Trust, partnered with the Lower Keys Guides Association, runs active tagging programs through the University of Miami. The "Save the Slime" campaign promotes safe handling practices.

Snook: Hold horizontally with one hand on the bottom lip and the other fully supporting the belly. Never hold vertically by the lip - it causes vertebral separation up to 2mm and connective tissue damage. Survival rates drop to roughly 40% when fish are oxygen-deprived during extended fights.

Always check current Florida Fish and Wildlife Conservation Commission (FWC) regulations before your trip. Season dates, bag limits, and slot limits change. What was legal last year may not be legal this year.
