The Electric ray Discopyge tschudii is distributed form southern Brazil to Peru. The main threat to this species is fishing. Discopyge tschudii is noncommercial and individuals caught are discarded on board. The present study analyzes the distribution and the morphological and reproductive characteristics of this ray in San Matías Gulf (SMG). A total of 1087 individuals were analyzed. The species presented an aggregated distribution with the main concentrations in the northern and eastern areas of SMG at depths below 100 m. Males ranged from 9 to 43 cm and females from 11 to 38 cm. The species presented sexual dimorphism. Males were larger and heavier than females and they also matured at larger sizes. Size at 50% of maturity was estimated ...
