Fishing the Pacific: Costa Rica Species Guide

Coast to Coast is a journey through Costa Rica’s three unique fisheries: the Pacific, the jungle, and the Atlantic. The series begins in the blue waters of the Pacific. Here, deep pelagic waters meet with the shallow waters of the coast, making one of the most productive fisheries in the world. Variety is the name of the game, as Heather and Curtis set out to check off as many new species as possible. From powerful pelagics to aggressive inshore species, these are the target species of Costa Rica’s Pacific Coast.

Pelagic Species of Costa Rica

The near-shore dropoff found in Costa Rica attracts numerous bluewater species. These pelagic fish spend their time traveling, hunting, and migrating through the Pacific Ocean. When conditions and seasons align, expect to encounter these pelagic fish species in Costa Rica.

Marlin

Costa Rica’s unique positioning on the map attracts a variety of marlin species. These include striped, black, and the legendary blue marlin. The addition of FADs (fish attracting devices) in recent years, as well as drop-offs, reefs, and an abundance of bait, are excellent hunting grounds for these billfish. The best months to target marlin are typically in the winter and early spring, but marlin can still be found throughout the year. Check out how to catch a billfish on the fly, HERE.

Sailfish

Positioned on the Pacific side, the billfishing grounds of Costa Rica are also home to sailfish. However, these are Indo-Pacific sailfish, not the Atlantic sailfish many anglers are familiar with. The Indo-Pacific sailfish grows a lot larger than its Atlantic cousins. They will also readily eat a fly. Here, dragging teasers over likely sailfish structure can raise fish into the boat wash. With a seasoned crew, a quick bait and switch will leave your legs shaking as you watch sails chase down your fly.

Wahoo

Wahoo are common pelagic fish found throughout the world. They can reach sizes of over 100 pounds, fight incredibly hard, and make excellent table fare. Wahoo are easily identified by their streamlined body, blue coloration, and dark stripes. These pelagic fish can frequently be found patrolling offshore reefs and structure. The best time to fish for these toothy predators is often first thing in the morning and last light.

Tuna

Tuna fishing in Costa Rica can be incredibly productive. The target species is yellowfin tuna. This species grows the largest, can be caught on a fly, and typically travels in small schools. In addition, several smaller tuna species can be found, including big eye tuna, skipjacks, and bonito. These species can also be caught on fly, although they do not grow as large as yellowfin. Some of these smaller species also make excellent marlin baits.

Near-Shore Species of Costa Rica

Costa Rica’s reefs, rock edges, and beaches are also home to a number of sought-after species. From inshore giants to unique fishing opportunities, these are the near-shore species of Costa Rica.

Snapper

Along the coast, rock edges, and reefs, anglers can find multiple snapper species. The largest and most sought-after is the cubera snapper. These fierce predators can reach sizes of over 100 pounds and have the attitude to back it up. They fight hard and have a wicked mouth full of razor-sharp teeth meant for crushing and shredding prey. Anglers can also come across mullet snapper, a smaller, more slender species found in similar areas to cuberas. In addition, several smaller snapper species are found throughout the coast, including the rock snapper.

Pacific Snook

The Pacific snook, or black snook, in a lot of ways, resembles the Atlantic snook. They live in similar habitats and have a similar appearance. However, the Pacific snook has a smaller mouth and slightly darker coloration. They can reach impressive sizes, with the world record ibeing just shy of 50 pounds, and fish pushing 50 inches are not unheard of. These giants receive little fishing pressure compared to the Atlantic species. Just make sure you bring your big gear, as you never know how big they will be.

Roosterfish

Next to billfish, roosterfish are the most popular species to target in Costa Rica. Image courtesy of 4 Corners.

Roosterfish are one of the most unique-looking and sought-after fish in Costa Rica. These fish have a unique, finger-like dorsal fin with long fin rays. They can reach sizes of over 100 pounds, but smaller fish are more typical. When you come across a school of fired-up roosterfish, teasing them is the best way to catch them. Typically, an angler or guide will use a hookless plug to lure the fish into a frenzy as they chase the lure to the boat. Throw your fly into the chaos and hold on. These smaller roosterfish are often found traveling in packs, aggressively chasing down baitfish schools.

Bluefin Trevally

Anglers familiar with the GT or giant trevally may be familiar with the bluefin trevally. These smaller cousins to the GT are found throughout the Pacific Ocean. They can be found patrolling the near-shore waters of Costa Rica and are typically fairly aggressive. Anglers can easily identify them by their stout bodies and distinct blue color. Don’t let their size fool you; even the small ones will put your gear to the test.
