A study on the reproduction of the red cusk eel Genypterus chilensis was conducted in the fishing area of Talcahuano, Chile. The mean sexual maturity and size at first maturity were determined in a sample of 490 specimens. The microscopic analysis showed the simultaneous presence of oocytes in different maturity stages, in mature individuals. This allows the characterization of the red cusk eel as a partial or multiple spawner. The frequencies of maturity stages in females showed a spawning period between July and October, and a secondary peak in March. The size at first maturity of the red cusk eel was 72.4 cm.
