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 &amp; MORALES-NIN, 2000; MORALES-NIN et al., 2005; KACHER &amp; AMARA, 2005; BELCARI et al., 2006). Consequently, we studied growth and estimated age, using...

A comparative study of the reproductive cycle of Ruditapes decussatus under natural (South of Tunisia) and controlled conditions (hatchery). The aim of this study was to describe and compare the gametogenic activity of Ruditapes decussatus in situ and in hatchery. Criteria of maturity were characterized and the positive role of conditioning in the success of artificial reproduction was underlined. Specimens sampled in the South of Tunisia were conditioned at the experimental station of Monastir (Tunisia). The parameters studied were the variation of the condition index and the frequency distribution of oocyte diameters. Results showed that the reproductive cycle was continuous in situ. Gametogenesis started in January and February. Gonadic activity...
