Balık çiftliklerinin denizel ekosisteme etkilerinin uzaktan algılama ile tespiti: Ildırı Körfezi

The Bay of Ildırı is one of the areas where the most intensive aquaculture activities have taken place along the Aegean coast of Turkey. In order to evaluate the possible impacts of aquaculture to the marine ecosystem by using remote sensing and geographic information systems, fieldworks performed in the bay between February 2010 and 2011. The impact is evaluated in terms of total suspended matter, Secchi depth and sea surface temperature. Images from MERIS sensor of the ENVISAT were used to determine distribution of Secchi depth and total suspended matter. Empirical algorithm performed after atmospheric corrections applying the analysis concentrated on the derivation of data from satellite imagery by artificial neural network technique. Geographical information system was used for data arrangement analysis and presentation purposes. Results show that as limitation of this study, there is no apparently impact of aquaculture activities to their environment in Ildırı Bay. Images of MERIS are not very sensitive because of its medium spatial resolution. Although it relatively lower resolution seems a problem to evaluate local impacts, the study will provide probably important input for further studies or will support as a complementary in field studies to increase understanding.
