Conservation Status
The Pejerrey, as per most recent data, are not currently classified as endangered or vulnerable and thus do not have a special conservation status. However, like all species, they are susceptible to changes in their habitat and need to be managed responsibly to preserve biodiversity and balance in their ecosystems.

Distribution
In South America, Pejerrey is commonly found in Chile, Argentina, Paraguay, Uruguay, and Southern Brazil. They tend to migrate towards warmer waters during colder months and are known to travel in schools.
Habitats
- Water type: Primarily freshwater, but can be found in brackish waters as well.
- Depth range: They usually stay near the surface, more specifically in the upper 10 meters of water.
- Temperature range: Prefer a temperature range between 10 to 23 degrees Celsius
When and Where to See
Pejerrey seem more active during warmer months of spring and summer. They are often seen in the early dawn and before sunset as they come closer to the shore during these times.
Best Fishing Locations
Some top locations to catch Pejerrey include the Parana River and the Rio de la Plata estuary in Argentina, the Uruguay River in Uruguay, and the coast of Chile. If specific locations are unknown, it can be helpful to look for areas with optimal temperature and shallow depth.
How to Catch
For baits, flies or small fishes are a good choice since Pejerrey is a carnivorous species. Fly fishing, trolling, and bottom fishing is the common fishing techniques used. The best time to fish for them is early morning or late afternoon, especially during warmer months.
Identification Guide
Pejerrey typically have a slim, elongated body with a silver tint. They have small mouths with conical teeth and a pointed snout. The dorsal fin is usually in the middle of the body.
Culinary
Pejerreyes are prized for their sweet, delicate taste and can be prepared in a variety of ways such as grilled, fried, or baked. They are low in fat and high in protein, making it a healthy choice for many meals. One popular recipe is ‘Pejerrey a la Plancha’ where they are grilled with a sprinkle of olive oil and lemon juice.
