En la localidad de Gualjaina, donde la cordillera empieza a ceder ante la estepa, corre este afluente del río Chubut: un río mediano de valle, de aguas claras y correderas prolijas, en plena transición de paisajes. Aloja trucha arcoíris, trucha marrón y trucha de arroyo.
Se pesca sobre todo con mosca: secas en las correderas, ninfas en los canales y streamers en los pozones y las juntas, con spinning liviano donde la modalidad está permitida. Las truchas de arroyo se esconden en los sectores más frescos y sombreados, mientras las marrones buscan los pozones profundos. En términos generales, el arranque de la temporada y el otoño son sus momentos fuertes, cuando el agua baja con buen nivel y color. Río de valle tranquilo y accesible, perfecto para una jornada de pesca prolija con vadeo a pie.
LD: 3 salmónidos menores de 35 cm. Devolución obligatoria de trucha de arroyo (fontinalis) desde el 01/03/2026.

For a species of 0.5 to 2 kg that lives in cold streams and lagoons, the ideal gear is light and sensitive, allowing you to enjoy the fight and present small lures and flies with precision.
Spinning:
Fly:
Round it out with barbless hooks if you are going to practice catch-and-release, a hook-removal tool (forceps), a soft-mesh (rubber) net so as not to harm the fish, and waders if you are going to wade into the cold water.
Gear is chosen according to the environment and the expected size. A versatile, concrete setup:

In October the species of Río Gualjaina are past their best moment. Off season does not mean there is a closed season.

Río Gualjaina is in the province of Chubut.
Spinning (general use, rivers and lakes):
Fly fishing:
Recommended accessories: rubber net (less harm to the fish for release), forceps for removing hooks, barbless hooks, and waders for safe wading in cold water.
The gear is matched to the setting and the size of trout you are after, but these setups cover most situations in Argentina:
Spinning (general use, trout of 1 to 3 kg):
Fly:
For trophy specimens (5-10+ kg at the Strobel): step up the power—medium/medium-heavy spinning with 15-20 lb braid and a robust fluoro leader, or a 7/8 fly outfit—because these are fish with strength and runs far superior to the average trout.
In every case: a well-adjusted drag, sharp hooks (barbless if you are going to release), and a rubber net to handle the fish with the least possible harm.
