As in much of the world, 2016 and 2017 have brought many surprises here in Costa Rica, including new and unusual weather patterns. As fishermen, we know to take such weather changes in stride, adapting our techniques and locations. Fortunately, the fishing for machaca – one of our favorite tropical freshwater fish species, continues to be outstanding. This year, we caught several machaca to 7 lbs., prime specimens of a unique and little known species that performs acrobatic jumps and aggressively takes topwater flies.

There are basically two distinct seasons that dominate our fly fishing experience in the lower tropical waters of both the Caribbean and Pacific coasts of Costa Rica. This is the distinct wet and the dry season, when the water levels in the rivers and lagoons are found to be influenced by the weather patterns along the mountain ranges that divide the country. Heavy rainfall in the mountains will cause river levels to fluctuate suddenly and this brings a lot of food and fresh water into the drainage systems on both coasts. The sportfish also react to this bounty of food and the fresh oxygenated water which certainly stimulates their feeding activity.

During the wet season the machaca feeds mainly on sub-surface insects, small baitfish and worms, beetles or grubs that are dislodged by heavy rainfall. When the dry season brings in bright sunshine skies, wind gusts and abundance of flowers, the use of  floating flies in flower patterns and colors, the buggy deer hair poppers and even some insect patterns in bright colors will stimulate instant strikes.

At any time of year, our float trips start early in the morning and the fishing is usually immediate as we cast the poppers under the trees, as far back as possible and near the shore line. Here the machaca wait for anything that resembles some of the food choices that are present at that time of the day. As this daylight progresses and the wind gusts ruffle the tree canopy along the river, the falling insects, fruit and in some instances flowers make for a feeding frenzy and immediate strikes are experienced. The casting of the surface popper has to be presented with little or no finesse since the falling fruit like poppers have to land on the water surface with a loud weighted popping sound. Then no movement of the popper is done, just leave it to drift naturally with a tight fly line for an immediate reaction when the machaca strikes. A line strike is preferable. The use of a wide gape hook also offers a better hooking possibility with the fruit and seed imitation poppers. The machaca possess formable teeth that make radical damage to many poppers.

We fish only the most beautiful, most pristine rivers to ensure a very beautiful trip, drifting down a tropical jungle lined river with lots of wildlife to be seen. We usually fish two anglers to a boat and stop regularly for rest stops and to see some of the wildlife encountered. At times we stop to afford many casts to feeding fish under particular fruit or flower producing trees. Sometimes the monkeys feeding in the trees offer a harvest of partially eaten fruit falling to the waiting fish below.

We regularly see troops of monkeys moving among the trees and even some other mammals rushing through the underbrush with an encounter with some crocodiles and many wader birds that have their preferred roosting trees and feeding ponds along the river. Iguanas are seen in various sizes with the occasional “Jesus Christ” lizard surface walking on the water between tree stumps.

The float trip lasts an average of six hours and is sometimes able to produce some snook and snapper along with the usual machaca. We prefer using 7 wt. fly rods with bug tapered floating lines. The snook and snapper generally prefer streamer flies in baitfish sizes and color tones.

Averaging about 7 to 10 fish per trip with the occasional trophy machaca weighing 7 lbs. to add to the excitement of the day. These acrobatic fighting sportfish are a real treat for a fly fisherman seeking a unique adventure in our tropical waters.

A Costa Rica Trout & Jungle Panfish Sampler

Fly fishing the cloudforest for trout.

We’ve just returned from a 6-day trip with client Chris, of California. Chris, a fly-fishing guide himself, had contacted us

to help arrange a custom trip and to guide him to some of Costa Rica’s more unusual, and more remote, fisheries. He wanted to catch trout in the cloud forests, then try for snook and tropical panfish in the lowland rainforests.

Our trip began high in the mountains above San Jose, near 9,000 feet, where we fished our favorite cloudforest river for trout. The fish were abundant, and hungry — and our two days fishing there were highlighted with great looks at one of the rarest, and most beautiful, of Costa Rican bird species, the resplendant quetzal. These birds — rarely seen even by the most avid of birdwatchers, are  often easily spotted on our fly fishing adventures.

After getting our fill of trout fishing, we changed gears — and lightened our clothing — and spent the remainder of the trip fishing in a roadless, remote jungle area along the northwestern Caribbean slope. Temperatures here average 30-40 degrees warmer than in the mountains where the trout live, and the species diversity reflects the much hotter, more humid maritime climate. We fished uninhabitated lagoons and

rivers under the playful gaze of monkeys and toucans, watched dolphins swim and caught many different species of fish, including snook, while throwing poppers into pinpoint pockets of rainforest lianas and trees draped in bromeliads and orchids. Chris’ outstanding casting and fishing skills greatly improved his success.


Finding New Rivers to Fish Machaca

At Fly Fish in Costa Rica, we love nothing more than to explore a new river, catch a new species, or discover a new technique. This year, we added multiple new machaca rivers to our offerings. These rivers are scattered throughout the country, which means we can usually accomodate the fly angler who, for example, is spending a week on the beach with his or her family in Guanacaste, or the business traveler with a day or a weekend off in San Jose.


Our cork ‘poppers’ are exact imitations of riverside fruit. They plop on the water and the machaca hit them with reckless abandon.

Anyone who has fished with us knows that the machaca (Brycon guatemalensis) is one of our favorite species: A cross between the better known North American shad and South America’s pirahna, these fish feast on poppers, fight hard and jump – a lot. We believe them to be the most under-rated gamefish in the Americas.

Fortunately, Costa Rica’s clean-running rivers, which drain the fertile flanks of the country’s highest volcanoes, provide ideal habitat for machaca. Most of Costa Rica’s rivers run through cloud and rainforests, rife with wildlife and stunning scenery, no matter what the time of year. Overhanging trees provide the machaca, an omnivore that feeds on fruit, flowers, frogs and fish, with abundant forage. We now design our poppers to mimic these riverside fruits — and they are deadly. It’s fast fishing, fun and absolutely unique to Costa Rica. Come learn something new with us!

A Banner Year for Costa Rica’s Freshwater Tarpon

When the rains subsided in early January this year, the giant tarpon began to show in our favorite rivers, chasing baitfish as they drained out of inland lagoons. These are ocean-going fish that make a many hundred kilometer voyage from the Caribbean to feast — a rare phenomenan found only in Costa Rica. We have fished for tarpon all over Central America, the Caribbean and the Florida Keys — and we guarantee you won’t find anything like this anywhere else. We fish in a full rainforest environment, with toucans, macaws and exotic hummingbirds as regular spectators, and monkeys cheering from branches in the trees above us. One of our most memorable trips this year was with Jan Orr, of Holland, who fished with us for five days. On his first day of fishing, a cold front was moving through our preferred fishing area; not uncommon and a normal part of fishing here. We jumped a small 25 lb. tarpon; but the fishing was slower than hoped. The next day Jan persevered — saw some very large tarpon and jumped a few — but struggled to bring one to the boat. This is a challenging fishing environment. The jungle encroaches on the river. Snags are numerous. The current can be strong. The odds are always against you when you fight giant tarpon on a fly rod here. But the big reward came near the end of Jan’s trip, when he landed this 200 lb. + tarpon on a 10 weight and our secret tarpon fly.

We saw many tarpon of this size over the course of the week, and jumped at least 20 – but bringing one to the boat is the moment of truth. Jan was very grateful for the experience — and we grateful for his company.  Please give us a call or email if you’re interested in trying this unique fishery.
