How to Catch San Juan Tarpon

Find instant access to premier tropical tarpon grounds in Puerto Rico.

As a passing rain shower subsided, I stepped onto the casting deck, rod in hand, willing a fish to strike. Like clockwork, the reel to my left screamed as the circle hook at the other end found its home into the jaw of our first triple-digit tarpon of the day. As we scrambled for the rod, the massive fish blasted out of the water with the San Juan skyline in the background. I ­realized this was indeed a special spot — and that you don’t always have to travel far to find big fish.

We flew into Puerto Rico last May to cash in on this productive urban tarpon fishery. Our guide, Capt. Juan Carlos Torruella, pioneered fishing the tarpon-rich backcountry of San Juan more than 25 years ago, and has since become an expert in fishing the waters of Puerto Rico both inshore and offshore. He is an IGFA representative for the area, and he recently earned recognition on Salt Water Sportsman’s 2012 list of 50 Top Charter Captains.

Torruella started out fishing these waters in the mid-’80s aboard a stripped-down 11-foot Boston Whaler, casting MirrOlures to willing tarpon. “That was before I could even throw a cast net,” he says. Now the San Juan fishery is primarily a live-bait game.

Back then, Torruella also moved beyond the backcountry lagoons in pursuit of tarpon into the main San Juan harbor, but there it’s a different deepwater game, fishing heavy bucktail jigs in depths of 50 to 60 feet. He’s long since eschewed the harbor fishery, and fishes the Torrecilla and San Jose lagoons exclusively out of the Cangrejos Yacht Club aboard his 20-foot TwinVee power cat, Extremist.

Choosing Lagoons

San Juan’s backcountry tarpon grounds lie primarily within two lagoons — Torrecilla and San Jose — which are connected by an intricate system of bait-filled natural creeks and man-made canals. While city sounds and planes overhead provide a regular reminder that you are in a bustling metropolitan area, limited shoreline ­development makes way for long, unbroken strands of healthy ­mangroves and fishy surroundings.

Significant dredging in the 1960s of the Torrecilla and San Jose lagoons to harvest fill for civil projects has left some big holes — some up to 50 feet deep — that provide fish-attracting ledges and cool-water refuges in the otherwise shallow lagoons. 

It was in one of these deep holes in the Torrecilla ­Lagoon that Torruella lost the biggest tarpon he’s ever seen here — a 200-plus-pound fish that wore through the leader after a four-hour battle.

“Three hours into the fight, he was in the 50-foot hole, fighting like a tuna, and after a 3½-hour fight, he jumped three times,” says Torruella. “It was crazy.”

His personal best tarpon that made it to the boat is a 160-pounder, caught in San Jose Lagoon. In the lagoon system, any fish over 100 pounds is considered a trophy, but 150-plus pounders are not infrequent during the spring and fall migrations.

While school-size tarpon, along with snook and jack crevalle, inhabit the lagoon system year-round and provide great sport on light tackle a mere 10-minute drive from downtown San Juan, the real attraction here is the big fish that roll in around February and hang around until mid-May, only to return for an encore in October.

Torruella splits his time between the two lagoons in search of finicky big tarpon, and either locale can run hot and cold. Water conditions vary significantly with rainfall (muddy water often means it’s time to pull out the artificials), and while low-oxygen cycles sometimes affect fish in San Juan Lagoon, tides are critical in the Torrecilla.

“The tide is the key to everything,” says Torruella. “When the tide’s really moving, the tarpon are really aggressive, then they tend to get fussy as it turns.”

Being there at the right time isn’t enough, however. You have to find the fish.

“You’re looking for the rolling fish and bait pods,” says Torruella. “Sometimes you’re also looking for birds. At certain times of year, the birds school up with the fish, especially in the morning.”

On our first morning out, we find ourselves running down a narrow mangrove-lined canal that leads to San Jose Lagoon. “Might want to sit down,” Torruella warns as he begins to stow rods on the approach to an impossibly low overpass. The oblong lagoon is bisected neatly by Teodoro Moscoso Bridge, and a deep crescent-shaped trench around the outside edge of the lagoon forms a sharp drop-off that helps to attract trophy tarpon.

We’d spend most of the first few hours dodging rain showers among a handful of other boats. Soon after the rain abated, however, the drag started to sizzle on one of the dead-bait rods in the gunwale holders, and soon enough, I was fighting a 100-pounder. We’d go on to jump more than a dozen fish ranging from 30 to 120 pounds over the next two mornings in steady action that Torruella still considered “slow.” His best single day saw him catch an incredible 56 tarpon for an island record that still hasn’t been beaten.
