| Growth parameters of any species are fundamental for biological or dynamic studies. The quality of the estimation for these parameters directly impacts on species stock assessment and, as a consequence, on fisheries management. In order to improve fishery and species stock management, growth analysis, especially by sex, is recommended. In this study, otoliths were used to estimate growth parameters of Merluccius merluccius Rafinesque, 1810. Hake is well-known as being a species in which otolith interpretation is extremely difficult. To estimate growth parameters, the first daily increment was validated as the tool for age determination. Otolith interpretation was done according to the last results of ICES cooperative research report. In total, a sample of... |

| Hake (Merluccius merluccius) is widely distributed in the Atlantic Ocean and the Mediterranean Sea. It is one of the most exploited demersal fish. In Tunisia, hake is captured from the north to the south (KHOUFI et al., 2010). Hake is an important species of economic interest and thus the subject of a large literature, but its biology remains insufficiently known, particularly on terms of age and growth estimations, which are essential for stock assessment and management. Otolith microstructure provides a useful tool for age determination of juvenile hake, based on daily increment deposition (ARNERI & MORALES-NIN, 2000; MORALES-NIN et al., 2005; KACHER & AMARA, 2005; BELCARI et al., 2006). Consequently, we studied growth and estimated age, using... |
