| A total of 807 Dipturus chilensis specimens (448 males and 359 females) caught in research cruises performed by the National Institute for Fisheries Research and Development (INIDEP) during 2011 and 2012 were analyzed. The cruises were carried out between (34°S-48°S) and 50-313 m depth. Mean size at first maturity (TL50) was estimated at 780 mm and 908 mm TL for males and females, respectively, values that represented about 80% of the respective maximum total length observed. Besides, latitudinal differences in sexual maturity estimates were detected. The total number of 4-7 reproductive seasons and 42-52 follicles or individuals of maximum annual potential fecundity estimated in this paper allow to suggest that each female would produce less than 300 eggs... |
