Coastal fish indicate human-induced changes in the Mediterranean littoral

摘要

Coastal fish assemblages were studied to asses two sorts of human impacts in south- western Apulia(SE Italy, Mediterranean Sea). Fish assemblages were evaluated by visual census along two rocky locations impacted by a sewage outfall discharging nearshore(S)and by date-mussel(Lithophaga lithophaga)fisheries(F), respectively, and at two control locations (Cs). Multivariate analyses showed that fish assemblage structures at S and F differed from those at Cs. Asymmetric ANOVAs indicated that species richness were significantly lower both at S(～27/100)and at F(～35/100)compared with Cs.
