Distribution and abundance patterns of decapod crustaceans in the Sado estuary, Portugal

Distribution and abundance patterns of decapod crustaceans in the Sado estuary, Portugal DISTRIBUTION AND ABUNDANCE PATTERNS OF DECAPOD CRUSTACEANS IN THE SADO ESTUARY, PORTUGAL BY ANA NEVES, HENRIQUE N. CABRAL 1 ) and LEONEL S. GORDO Universidade de Lisboa, Faculdade de Ciências, Instituto de Oceanografia & Departamento de Biologia Animal, Campo Grande, 1749-016 Lisboa, Portugal ABSTRACT The decapod crustacean community of the Sado estuary was sampled monthly, between May 2001 and April 2002, using a 4 m beam trawl with 10 mm mesh size. The assemblage was composed of 33 species (9 Natantia and 24 species of Reptantia). Only 5 species ( Crangon crangon , Macropodia rostrata , Pilumnus hirtellus , Carcinus maenas , and Liocarcinus navigator ) were present in more than 40% of the samples. Few species dominated the community: C. crangon and C. maenas were the most important species in numbers (accounting for 63% and 17% of the total number of individuals, respectively), while C. maenas , Maja brachydactyla , and C. crangon dominated in biomass (73%, 9%, and 8%, respectively). A marked spatial and seasonal pattern was noticed: the inner areas, with shallower depth, less water transparency, and lower salinity, presented a high abundance of C. crangon , while in the outer areas a more diverse assemblage http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crustaceana Brill
