Length-weight relationships (LWR) were described for fourteen demersal and pelagic fish species; whiting (Merlangius merlangus), red mullet (Mullus barbatus), picarel (Spicara maena), scorpion (Scorpaena porcus), anchovy (Engraulis encrasicolus), sprat (Sprattus sprattus), horse mackerel (Trachurus mediterraneus), bluefish (Pomatomus saltatrix), turbot (Scophthalmus maximus), thornback ray (Raj...

It is well established that increasing mesh number in the circumference of a diamond-mesh trawl codend can reduce size selection for round fish, whereas selection for flat fish species is unaffected. This effect has also been documented in Mediterranean trawl fisheries. In contrast, no information is available with regard to the effect of increasing mesh number in the circumference of square-me...

Sagittal otolith shape analysis is one of the most widespread techniques worldwide to discriminate fish stock units, as this proxy integrates both environmental and genetic factors. All previous studies have been carried out using two-dimensional (2D) images, a partial representation whole otolith. However, prior identification unit boundaries, influence other potential drivers controlling must...

The relationships between total mercury (Hg) concentration and stable nitrogen isotope ratio (delta(15)N) were evaluated in Mullus barbatus barbatus and M. surmuletus from the Mediterranean Sea and M. barbatus ponticus from the Black Sea. Mercury concentration in fish muscle was six times higher in the two Mediterranean species than in the Black Sea one for similar sized animals. A positive cor...

population dynamic parameters of red mullet, mullus barbatus (n=592) caught by trawlers operating in arzew gulf (algeria) in the western mediterranean were studied. samples were collected between february 2013 and january 2014. females ranged from 10.9-23.2 cm in total length and 12-149.2 g in weight whereas males length was comprised between 12.6 and 19.7 cm and weight between 21.3 and 99.9 g....
