Abstract
Summary The von Bertalanffy (vB) growth parameters for pink cusk‐eel (Genypterus blacodes) were estimated for the Chilean austral‐zone (41°28′–57°00′S) by gender and management fishing zones. A total of 47 026 samples were collected between March 1982 and May 2004, with total length ranging from 19 to 154 cm. Age determinations, based on the reading of saggital otoliths, were between 1 and 14 years in males and between 1 and 16 years in females. Statistical differences in growth were found between the sexes and management fishing zones. For the combined sexes the vB growth parameters for the northern‐austral zone (41°28′–47°00′S) were: l∞=111.452 cm, k = 0.186 year−1, t0 = −0.912 year; and for the southern‐austral zone (47°00′–57°00′S): l∞ = 123.447 cm, k = 0.147 year−1, t0 = −1.779 year.
