Pirarucú Lodge Fishing Report 2026 | Arowana Everywhere, Arapaima to Remember Week 8 | Oct. 16–29

A group of four anglers took to the water during this stretch of the season, and the fishing quickly delivered impressive results. One guest joined Pirarucú after completing his time at Rio Marié, extending his Amazon combo journey with a few more days in a completely different fishery.

Over the period, the group landed 143 fish, including arapaima, tambaqui, and arowana. Arapaima once again brought the scale and raw power that define the experience, while an exceptional number of arowana kept the action constant throughout the fishery. Two tambaqui made the week historic. And when it came to the biggest arapaima, a familiar name appeared once again.

River Conditions

Water levels and overall conditions remained extremely favorable, creating an excellent scenario across the fishery.

With the 2026 season entering its final stretch, these conditions continue to give the guide team strong confidence in the opportunities ahead for arapaima, tambaqui, and arowana.

Fishing Stats

Total fish landed: 143

Arapaima: 27
Tambaqui: 28
Arowana: 88

Biggest arapaima: 2.10 meters

Highlights of the Week

Two Potential Line-Class Records on Fly

Some of the week's most significant moments came from tambaqui. Two fish of 14.5 lb and 16 lb were landed on fly, and both are potential line-class records.

Tambaqui are powerful, selective, and notoriously difficult to bring to hand on fly tackle. Landing one of this size is an achievement on its own. Landing two potential records in the same week shows how special this fishery is.

The catches are now being documented for official IGFA record submission.

88 Arowana

One number immediately stood out: 88 arowana landed.

Fast, visual, and highly acrobatic, arowana brought a completely different rhythm to the fishing and became a defining element of the period.

For anglers moving between the three primary species at Pirarucú, they offer a distinct challenge from the immense power of arapaima or the sustained strength of tambaqui. This week's numbers also showed how productive and diverse the fishery can be.

Rodrigo Does It Again

The biggest arapaima of the period was landed by Rodrigo Salles.

By now, it has become something of a running mystery within Untamed Angling. Whenever Rodrigo visits one of the operations, he seems to find a way to connect with one of the standout fish.

Experience? Instinct? Luck? Whatever the explanation, the pattern continued at Pirarucú.

His 2.10-meter arapaima added another memorable fish to his list and one more story to a season already filled with remarkable encounters.


Three Species, One Productive Fishery

Along with the strong arapaima and arowana numbers, 28 tambaqui added another layer to the fishing.

Their strength and endurance continue to make them an increasingly important target for anglers discovering what these Amazon fish can deliver on fly tackle.

Together, arapaima, tambaqui, and arowana produced 143 landed fish, each species demanding a different approach and offering its own kind of challenge.

Looking Ahead

The excellent water conditions are an encouraging sign as the 2026 season moves toward its final weeks.

With 143 fish landed, 88 arowana, and a 2.10-meter arapaima, Week 8 combined consistency, variety, and another standout encounter with one of the Amazon’s most extraordinary freshwater fish.

The fishery is in excellent shape, and everything points toward a strong final stretch of the season.
