Fish Species

Blue Marlin
Blue Marlin

A Blue Marlin has an elongated body, a spear-like snout or bill, and a long rigid dorsal fin, which extends forward to form a crest.

Marlin prefer the higher temperature of surface waters, feeding on mackerel and tuna, but will also dive deep to eat squid.

They are among the fastest fish in the ocean, and use their spears to slash through dense schools, returning to eat their stunned and wounded victims.

Sailfish The Pacific Sailfish native to the Indian and Pacific Oceans. It is dark blue on top, brown-blue laterally, silvery white underbelly; upper jaw elongated in form of the spear; first dorsal fin greatly enlarged in the form of a sail, They have a large sharp bill, that they use for hunting sardines, tuna, and mackerel.

They prey on the faster fish in the sea because their top speed has been clocked at 68 mph.


Dorado The Dorado or Mahi-mahi live 4 to 5 years. Catches average 15 to 29 lb. They seldom exceed 35 lb. They have compressed bodies and long dorsal fins extending nearly the entire length of their bodies.

They are distinguished by dazzling colors: golden on the sides, and bright blues and greens on the sides and back.

Mature males have prominent foreheads protruding well above the body proper.


Amberjack Amberjacks are the largest of the jacks. They usually have dark stripes extending from nose to in front of their dorsal fins.

They have no scutes and soft dorsal bases less than twice the length of the anal fin bases.

They are usually 40 pounds or less and are found associated with rocky reefs, debris, and wrecks, typically in 10 to 40 fathoms.

Red Snapper

Red Snapper The Red Snapper or Pargo commonly inhabits waters 30 to 200 feet deep or more. All feature a sloped profile, medium-to-large scales, a spiny dorsal fin, and a laterally compressed body.

The coloration of the red snapper is light red, with more intense pigment on the back.

A red snapper attains sexual maturity at 2–5 years old. An adult snapper can live for more than 50 years and weigh 50 pounds.


Snook Snook or Robalo are caught year round in the rivers and river mouths on the Pacific and Caribbean Coast.

Snook are also caught in some of the rivers, lakes, and lagoons along the Costa Rica / Nicaragua border.

There are lots of really big Snook caught every year in Costa Rica. They averages 5 lbs., with record catches up to 30 lbs. If you catch a run you can get into some great fishing and great eating,

Striped Marlin

Striped Marlin The Striped Marlin found in tropical to temperate Indo-Pacific oceans not far from the surface.

It is a large commercial game fish with a record weight (at 1982) of 190 kg, and a maximum length of 420 cm.

A predator that hunts during the day from close to the surface to about 100 meters or so. They feed on sardines, mackerel, and squid.

Yellowfin Tuna

Yello fin Tuna The Yellowfin Tuna is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide. One of the largest tuna species, reaching weights of over 300 pounds.

The second dorsal fin, the anal fin, and finlets between those fins and the tail are bright yellow, giving this fish its common name.

The second dorsal and anal fins can be very long in mature specimens, reaching almost as far back as the tail.


Wahoo The Wahoo found worldwide in tropical and subtropical seas. High-quality flesh makes it a prize game fish.

In Central America refer to this fish as Peto.

The body is elongated and covered with small, scarcely visible scales; the back is an iridescent blue, while the sides are silvery, with a pattern of irregular vertical blue bars and have razor-sharp teeth. Wahoo can swim up to 60 mph.

Cubera Snapper

Cubera snapper is a subtropical species has an elongated and slender body with a long pectoral fin, a continuous dorsal fin, and a fairly truncate-shaped caudal fin. Its mouth has thick lips and large teeth. The maximum reported size is 160 cm. The species is reef-associated, living inshore or nearshore, over rocky ledges and overhangs. It normally occurs at depths ranging from 18 to 55 m.

Rooster Fish

Rooster Fish The roosterfish a game fish found from Baja California to Peru. It is distinguished by its “rooster comb”, seven very long spines of the dorsal fin. Roosterfish can reach over 4 ft. in length and over 100 lb in weight.

The weight of the average fish hooked is about 20 to 50 lbs. The fish is popular game fish, but like most fish in the jack, the family is not considered a good eating fish.

Sierra Mackeral

The Paci?c Sierra Mackerel is found along the coasts of Mexico and Central America. A member of the Scombridae family of mackerel the Paci?c Sierra Mackerel is an eastern Paci?c ?sh that is excellent to eat. It is marketed fresh and frozen. It resembles the Spanish mackerel in appearance, and the all-tackle world record is an Ecuadorian? sh of 18 pounds caught in 1990.

Fishing Methods

There probably are as many costa rica fishing techniques and fish-catching tricks as there are anglers on the water, but the how-to aspect of sport fishing boils down to a few basic, tried-and-true fishing methods that have worked for as long as man has been trying to catch fish on a hook and line. If you master these basic methods, you’ll become a successful angler.

Beam trawl:

In this type of trawl the mouth or opening of the net is kept open by a beam which is mounted at each end on guides or skids which travel along the seabed. The trawls are adapted and made more effective by attaching tickler chains (for sand or mud) or heavy chain matting (for rough, rocky ground) depending on the type of ground being fished. These drag along the seabed in front of the net, disturbing the fish in the path of the trawl, causing them to rise from the seabed into the oncoming net. Electrified ticklers, which are less damaging to the seabed, have been developed but used only experimentally. Work is also being carried out to investigate whether square mesh panels (see below) fitted in the ‘belly’ or lower panel of the net can reduce the impact of beam trawling on communities living on or in the seabed.


The simplest of costa rica fishing methods can also be the most effective. As its name implies, still-fishing is a matter of putting your bait in the water and waiting for a fish to find it. This method will catch most kinds of fish and can be used from a boat, a dock, a jetty or from shore. Depending on water depth and what you’re trying to catch, you may want to still-fish near the surface, at a mid-water depth, or right down on the bottom. Using a float, or bobber, makes it easy to fish near the surface, or you can add sinkers to your line to fish deeper.

Demersal otter trawl:

The demersal or bottom trawl is a large, usually cone-shaped net, which is towed across the seabed. The forward part of the net, the wings is kept open laterally by otter boards or doors. Fish are herded between the boards and along the spreader wires or sweeps, into the mouth of the trawl where they swim until exhausted. They then drift back through the funnel of the net, along the extension or lengthening piece and into the cod-end, where they are retained.


The term casting actually has two meanings in fishing. It describes the act of using a rod, reel and line to carry your bait or lure out into the water. It also is a specific fishing method, as opposed to still-fishing and other methods we will describe here.

There are times when a moving lure works best, especially for some fish species. At other times you may want to place a lure in a particular spot, such as right next to a submerged stump 30 feet from shore or under a tree that’s leaning out over the water. These situations are when casting is the fishing method that offers the best chance of catching fish. It’s the kind of sports fishing where you cast and retrieve, usually with an artificial lure, to fish waters where fish might be lurking and to coax them into striking. Spinners, wobbling spoons, plugs and spinnerbaits are lures commonly used for casting.


Many of the lures used in casting also work for trolling, because it’s another fishing method that requires movement to be effective. Trolling is simply dragging a lure, bait or a bait-and-lure combination through the water, using a boat rather than casting and retrieving to provide movement.


Some artificial lures function best if they’re worked through the water in an up-and-down motion, commonly referred to as jigging. Lifting and dropping the rod tip is what provides the jigging motion. Leadheads are the most common kind of jig, but for some fish species, especially saltwater salmon and bottomfish, the jigging lure might be a long, thin, slab of lead or other metal in the shape of a herring or other baitfish.

Fly Fishing:

Artificial flies are nothing more than fur, feathers, thread, tinsel and other materials tied around a hook to resemble an insect, a grub, a minnow or some other small morsel that a fish might eat. Because they are often very small and always very light, they can’t be cast like a heavy lure. For that reason, they are usually fished with special lines, rods and reels designed just for this kind of fishing.


Free diving, using mask and snorkel or scuba diving is a traditional method of collecting lobster, abalone, seaweed, sponges and reef dwelling fish, groupers and snappers. In deeper waters helmet diving systems using air pumped from the surface are used.

Gill Nets :

Are walls of netting which may be set at or below the surface, on the seabed, or at any depth inbetween. Gill netting is probably the oldest form of net fishing, having been in use for thousands of years. True gill nets catch fish that attempt to swim through the net, which are caught if they are of a size large enough to allow the head to pass through the meshes but not the rest of the body. The fish then becomes entangled by the gills as it attempts to back out of the net. The mesh size used depends upon the species and size range being targeted.
