In this study, the impacts of marine aquaculture facilities on the environment were evaluated. For this purpose, sea water and sediment samples were collected at two stations which are near by the fish farm where sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) are grown in net cage in vicinity of Karaburun Penunsula in monthly period between December 2004-November 2005. Physico-chemical variables (temperature, salinity, pH, dissolved oxygen, secchi depth) and nutrients (nitrite, nitrate, ammonium, phosphate, silicate) in the seawater samples and organic carbon (%), amount of burnable substances (%) in sediment samples were investigated. The results were below the detection limits-0.24 μg-at/L for nitrite- N, 0.04-0.80 μg-at/L for nitrate-N, 0.15-1.70 μg-at/L for ammonia-N, below detection limits - 0.32 μg-at/L for phosphate-P, 0.11-6.35 μg-at/L for silicate, 1.22-11.81 (%) for organic carbon and 4.36-28.11 (%) for amount of burnable substances.
