Résumé :	The response of meiofaunal communities to seabed organic enrichment was investigated in three fish farms within Greek coastal waters. Sampling took place during November 1995 and April 1996. Samples taken at stations close to farms showed a significantly higher abundance (by a factor of 2-5) than those taken at the control sites during both seasons. This increase was mainly attributed to nematode density and was more conspicuous at farms with a silty substrate rather than at coarse sediment ones. The use of the BIOENV method showed that Redox, Total Organic Carbon and ATP concentrations in the sediment were the factors best explaining the multivariate patterns in the meiofaunal community. It is suggested that analysis of meiofauna may provide a sensitive tool for detecting early signs of benthic organic enrichment near fish farms.
