who is the peixe-rei-do-maule
The Maule pejerrey is a silverside fish of the family Atherinopsidae, reaching 30.5 cm. It lives in lakes and rivers in central and southern Chile, between the bottom and the midwater. Like other silversides, it has a slender, elongated body with a silver band along the flank. The region's climate is temperate. It is considered vulnerable, which calls for returning the fish to the water.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the peixe-rei-do-maule; in the meantime, see the similar species.

From the austral pejerrey, which is also from Chilean rivers, it is told apart by maximum size, 30.5 cm, smaller than the other's 36.5 cm, and by range: lakes and rivers in central and southern Chile.
