Ricostituzione delle risorse di pesca in un'area precedentemente soggetta ad intenso sfruttamento: dinamiche a larga scala del popolamento ittico e della struttura trofica della comunità marina. Rapporto finale MIUR. Restoration of depleted fisheries resources: large-scale dynamics of the fish assemblage and of the trophic structure and food web of a marine ecosystem subject to a trawl ban

This report presents the results of four seasonal trawl surveys conducted in the Gulf of Castellammare, which has been a trawl exclusion zone since 1990, and in two control areas open to trawling i.e., the Gulfs of Termini Imerese and of Sant'Agata. The objectives of the study were (1) to investigate the biomass, composition, diversity, size structure and trophic structure of the fish community in the untrawled gulf contrasted with the trawled areas, (2) to investigate the dynamics and biology of a fishery target species, the red mullet Mullus barbatus in the untrawled gulf
