A big tarpon flashes a boatside, stull full of vigor.

You’ve seen the pictures. Giant fish hanging in the air as bright and shapely as a quarter-moon. Well-dressed angler standing at the bow, six hundred dollars worth of graphite bent nearly to the breaking point.

At home or the office, you study the image until you can almost feel sweat and salt water drip from the pages. You imagine you are there.

More than anything, you want one of those fish. You’ve caught enough snook or redfish to justify the sticker on the back of your sport ute. Maybe even tugged on a few tarpon in deep water at a bridge or pass.

But there’s just something about watching that mythical, metallic beast explode over a crystal-clear flat, something awesome that makes you tingle deep in your rib cage. You don’t care if you’re casting a fly or a live pinfish. You have to catch your tarpon.

Some veterans say shallow-water tarpon fishing is harder than ever. Too many boats on the water these days, too many jetskis, too many anglers. Forget the Florida Keys, go to Belize, some say.

On the other hand, fishing techniques and tackle have undergone tremendous refinements over the years. So have Florida tarpon anglers, who continue to find new avenues in their home state, from Pine Island Sound to St. George Sound. Even heavily traveled fisheries on the Keys oceanside, Biscayne Bay, Florida Bay and the flats of Homosassa are slowly revealing their secrets to anglers willing to study the “new” travel routes and feeding patterns of migratory fish. In other words, if you feel you’re ready for the challenge, you can catch tarpon on the flats.

What follows is an outline of what could be considered the “new” basics, spins on traditional tactics for modern tarpon fisheries.

Presentation: Quick and Accurate

Start by losing your fascination with distance casting—especially you fly fishermen. For most anglers, medium-range casts, 50 to 60 feet or so, are more accurate and land more softly. When the heat is on, you’ll nearly always be better served by making a quick, well-directed medium-range cast than by opening your bail and letting it rip or trying to shoot the entire fly line. Practice accordingly.

Keep in mind that one of the biggest problems novice casters encounter is calculating the angle and distance needed to intercept moving fish. Wind direction and velocity, current and drift all factor into the equation. If your boat is moving toward the fish, closing the gap, you may have little time to cast. Moreover, because there will be less drag on the line, your lure or fly will tend to sink faster. You’ll have to start the retrieve immediately, and strip or reel fast to stay within the strike zone. On the other hand, if your boat is being pushed away from the fish, you’ll probably need to wait until they get a bit closer to make your cast. Then you may have to delay the retrieve, barely twitching your rod or fly line to impart action; that way your offering will enter the strike zone and stay there long enough for the fish to focus on it.

Because tarpon are so well equipped for nightly ambush sessions (hence their large eyes and cavernous, high-angled mouths), they just won’t expend much energy chasing a morsel during daylight hours. This is especially true during the spring-summer migration, when their minds are on traveling and spawning. Feeding then becomes an afterthought—that is unless your lure or fly lands conveniently in the path of a fish.

Timing is everything. You want the opportunity to retrieve your offering into the right position or even attempt a second cast if the fish alters its course or your initial cast doesn’t land where you want it to. You may have heard that elephants eat peanuts and are afraid of mice. Likewise, tarpon will feed on small crustaceans and baitfish, but they can sense there’s something wrong when a tiny creature rushes toward them menacingly. Even the largest of silver kings will turn tail when your offering runs at them instead of away from them, like scared prey would. That’s what angle is all about.

Inexperienced casters are often surprised by the deceptive speed of tarpon, which cruise much faster than smaller flats dwellers. That usually causes anglers to delay the start of their cast and, in the case of fly rodders, it can also translate into a few too many false casts. Whether using a plug, a jig or a fly, the results of a late cast are invariably the same: Either the fish detect motion and spook, you overshoot the fish, or there isn’t enough time for your offering to sink to the desired depth. It can be infuriating watching a school of tarpon swim right under your undetected lure or fly.

So always be ready to cast when you are searching for tarpon. Keep your finger on the line with the bail of your spinner open, or your reel in freespool with your thumb on the spool if you are plug casting. And if you are a flyfisher, learn to deliver your fly with just two false casts—and sometimes, just one—and figure out how long it takes your fly to sink so you know how far ahead of the fish it should land.

For tarpon on the flats, being quick on the draw is an absolute requirement.

Staking Out: Where and How

A chart and some grasp of tarpon behavior can help you locate fishing spots, but you are still going to need time on the water to figure out exactly if, when and how the fish travel in the area you intend to explore. Keep a journal, and record the locations, tides and weather conditions during your good days and your bad ones.

Charts for various regions can be purchased at local tackle shops, or you can order one from the National Oceanic and Atmospheric Administration, 1-800-638-8972.

On Biscayne Bay, my home waters, tarpon begin trickling out of their winter havens in inlets and cuts sometime in late April. When the water temperature reaches the 75-degree mark, it is time to keep your eyes and ears open for the first schools of fish moving south across the flats. While it is true that not all the fish follow the same path, most tend to travel along the outskirts of the bay’s oceanside flats. Tarpon like to follow edges; look on a chart for pronounced drops, say one where the bottom drops from a 4- or 5-foot flat to a depth of 8 or 10 feet, and you’ll have a decent chance to locate some tarpon.

A Biscayne Bay chart (NOAA charts 11462, 11464 and 11465) will reveal a number of likely intercept points from Cape Florida on south. Tarpon tend to follow a straighter path once they get down past the so-called finger channels in the bay, where you’ll see a well-defined line running along the outer edge of the flats. The fish often change course as the tide rises and falls; spots that are hot during low tide may be cold as ice when the water rises, as the fish are able to take shortcuts across shallower areas. But that’s something you can only figure out through exploration. One of the few constants you’ll find is that the fish move slowly during periods of slack water.

Staking out your boat at points and bends along these tarpon highways is a great way to get initiated, and even top anglers and guides do it with some frequency. Curtis Point, a spot on the outside of Old Rhodes Key, got its nickname because famous Capt. Bill Curtis has become a fixture there for over three decades, often staking out early in the morning during tarpon season. But there are other excellent stakeout spots near Soldier Key, the Raggeds, Elliott Key and Caesars Creek. A couple of points farther south off north Key Largo have paid off for me when I needed to get away from weekend boat traffic.

As long as you can properly position your boat with respect to the wind and current, and still give yourself a clear shot at incoming fish, you are golden. Where the bottom is too hard for your pushpole to penetrate, you can use your anchor; either way, you’ll want a release clip to free your boat if you hook a tarpon and need to give chase. A brightly colored buoy is also a must if you want to find your anchor when you return after fighting the fish.
