Özet

This study presents the domoic acid (DA), responsible from Amnesic Shellfish Poisoning (ASP), levels of plankton net samples in the Sea ofMarmara during April, July and October 2019. Plankton net samples were collected from 13 stations, which were located close to the Istanbul metropolitanarea, and along the east and southwest parts of the Sea of Marmara. DA measurements were done by high-performance liquid chromatography (HPLC),using the diode-array detection (detection limit (LOD): 0.108 µg mL−1). Twenty-two out of the 26 plankton net samples (84.6%) were found to contain DAduring the study period and the concentrations varied between 0.22 and 3.45 µg mL−1. Possible relationships between physical parameters (salinitytemperature) and DA concentrations were investigated. DA production was mainly controlled by salinity (r:0.47, p<0.05; n:26) along the study period. Thesedata may be used to consider the probability of finding similar conditions in different parts of the Sea of Marmara in order to determine the potential risks ofDA to local mussel aquaculture and fisheries.
