Puyen grande
A scaleless, bottom-dwelling native of the cold, deep lakes and rivers of Patagonia, the puyen grande is one of the larger members of the Galaxiidae family — a group of fish that predate salmonids in the Southern Hemisphere.
Its range runs from central Chile south through the Patagonian Andes, Tierra del Fuego, and the Falkland Islands. Most anglers fishing its waters will never see one; it lives in the depths and is more a measure of ecosystem health than a fishing target.
Scientific Name: Galaxias platei
Also known as Puye, Puyen, Tollo, Plate's Galaxias
- Smooth, scaleless skin — slippery to the touch, which immediately distinguishes it from most other freshwater fish in its range.
- A large galaxiid by family standards, reaching about 35 cm (14 inches); juveniles between 2–4 years old typically run 10–18 cm (4–7 inches).
- Bottom-oriented body shape suited to life on or near the lake floor, consistent with its demersal habits in deep water.
What to know
Habitat Distribution
- Native to South America: central and southern Chile from the Valdivia region southward, through the Patagonian Andes of Argentina, Tierra del Fuego, and the Falkland Islands.
- A cold-water specialist found in Patagonian lakes and rivers, capable of tolerating water with low dissolved oxygen — conditions that exclude many other species.
- In Tierra del Fuego, it is one of only three native freshwater fish species regularly encountered, making it an ecologically significant component of those waters.
Specific Spots
- Gravitates toward the deepest zones of lakes, where low light and cold temperatures reduce exposure to introduced predators like trout and salmon.
- Stays close to the bottom — rocky or soft substrate — where it can access the crustaceans that make up its diet.
