Ages of the fish under study ranged between one year and 14 years (15.5-43.5cm fork length). Age distribution was related to depth. The von Bertalanffy growth parameters for males were Ld^! = 49.1cm, K = 0.099 yearu-1 and td0 = -4.11 years, and Ld^! = 57.1cm, K = 0.081 yearu-1 and td0 = -4.16 years for females, obtained by length-age pair values. For all individuals the von Bertalanffy growth parameters were Ld^! = 53.5cm, K = 0.085 yearu-1 and td0 = -4.33 years. There were no differences in the growth parameters between males and females. Also, the growth parameters of the alfonsino under study did not differ between those of alfonsino from New Caledonia and the Izu Islands (Japan), but they differed significantly from those from New Zealand. 收起
