Description:
In June 2000 and July 2002, two mucous aggregation events of large proportion occurred in the Adriatic Sea. In order to assess the possible effects that the events had on the macrofauna, we studied macro-zoobenthic assemblages and mussel culture (Mytilus galloprovincialis). Structural parameters of macro-zoobenthos and growth parameters of mussels were recorded. The study area was a mussel farm located 5 nautical miles off Porto Caleri (Rovigo, Italy) in the Northern Adriatic Sea. Between May 2000 and August 2002, two sites were sampled in this area and univariate and multivariate techniques were used to describe the macrobenthic community. Two-way ANOVA showed that mean values of species number, density (individuals m^-^2) and Shannon-Wiener's diversity were significantly influenced (p
