Depth-size trends in western Mediterranean demersal deep-sea fishes
Se discute y argumenta la distribución de los peces en función de su talla. Gráficos, Tallas, Tablas. We analyze the bathymetric trends of demersal deep-sea flshes in the Catalan Sea (NW Medlterranean) between 1000 and 2250 m depth In the first part of the study, only the pattern shown by the whole...
