Última Growth models fitted to Dipturus chilensis length-at-age-data support a two phase growth RChHN AVERSA,MARINA I; DANS,SILVANA L; GARCÍA,NÉSTOR A; CRESPO,ENRIQUE A. Age and growth for the beaked skate was estimated from bands in the vertebral centra of 689 individuals obtained from incidental catches of the Argentine hake (Merluccius hubbsi) fishery. Age bias plots and indices of precision indicated that ageing method was precise and unbiased (% CV = 3 % PA = 82.09 %). Edge and marginal increment analysis of the vertebrae support the hypothesis of annual band pair deposition. Three growth models were fitted to length-at-age and the two-phase growth model produced the best fit. This feature has never been described before for D. chilensis and can be related to changes in energy allocation and the shift from juvenile to adult phase. The unrealistic biological estimates of the von Bertalanffy growth model illustrates the... Tipo: Journal article Palavras-chave: Beaked skate; Dipturus chilensis; Growth; Two-phase growth.
