Escape, discard, and landing probability in multispecies Mediterranean bottom-trawl fishery

Abstract Commercial bycatch species and their exploitation pattern in the Mediterranean trawl fishery are little studied. The present work examines overall size-selection pattern, both regarding sea fisher onboard vessel, for seven commercial using different codends. applied selection model predicted escape, discard, landing probability each simultaneously, a useful method providing information important fisheries management under ecosystem approach. Among studied codends, 40-mm diamond mesh codend, still use non-EU fleets, was found unsuitable stocks all cases. square codend (40S) appropriate blue whiting (Micromesistius poutassou), comber (Serranus cabrilla), bogue (Boops boops) sustainability. 50-mm (50D) more suitable than only spotted flounder (Citharus linguatula). Both 40S 50D codends were picarel (Spicara smaris), whereas none ensured sustainable blackbelly rosefish (Helicolenus dactylopterus), streaked gurnard (Chelidonichthys lastoviza). results discussed relation to juvenile protection, discard mitigation, behaviour, factors sustainability of Common Fishery Policy Sea.
