摘要: This study examined the effects of organic enrichment on water column, sediments and macrofauna caused by a fish farm in Mediterranean Sea. Samples were collected four sampling campaigns over one-year cycle. Significant differences found column dissolved oxygen, inorganic nitrogen, phosphate total phosphorus concentrations between control. The increase nitrogen at modified stoichiometric ratios nutrients, with silicate acting as limiting nutrient 11% more than Nevertheless, chlorophyll concentration was higher control station, probably due to fouling underwater structures. sediment matter, redox potential Canonical Correlation Analysis indicated that phosphorus, and% gravels accounted for 68.9% variance species data. Changes observed macrofauna, decrease number up nine-fold abundance respect
