dc.description.abstractComber is an important bycatch species in the trawl fishery both in the Mediterranean and the Atlantic. Age and growth studies have been restricted to the eastern Mediterranean and no methodologies were ever applied to ensure accuracy and precision. In this study a total of 471 otoliths from specimens ranging from 12 to 26 cm were used. Precision indices showed a high level of agreement between readers and no evidence of systematic disagreement was obtained. To estimate fish growth and due to the absence of individuals smaller than 12 cm, three approaches were used to estimate the von Bertalanffy growth parameters: whole otolith readings, back calculation and a combination of both methodologies. Akaike’s information criterion suggests that the back calculation approach was the best one for describing comber growth: TL = 25.26 [1−e(−0.21(t+1.72)]. Natural mortality estimates varied between M = 0.44 year−1 and M = 0.48 year−1 while estimates of the fishing mortality varied between 0.12 year−1 and 0.16 year−1 and the exploitation rate between 0.20 and 0.27.pt_PT
