| In the present study, it was aimed to assess of the quality of fish grown in a recirculation aquaculture system (RAS). For this purpose, three sturgeon species especially i en e el en tae tii, i en e ae ii, and i en e tellat were investigated. Concentrations of certain metals (Cu, Cd, Pb, Zn, Fe, Ni) in gills, liver and muscle samples were examined. Metal concentrations in i en e el en tae tii were; Fe:172.43-196.52 μg g-1, Cd: 0.21-0.33 μg g-1, Cu: 29.65-45.11 μg g-1, Ni: 0.52-0.86 μg g-1, Pb: 14.24-19.63 μg g-1, and Zn: 60.13-88.15 μg g-1. In i en e ae ii, metal concentrations were; Fe: 151.47-182.32 μg g-1, Cd: 0.18-0.36 μg g-1, Cu: 27.17-38.52 μg g-1, Ni: 0.72-0.98 μg g-1, Pb:16.45-25.16 μg g-1, and Zn: 72.14-95.41 μg g-1. Concentrations in i en e tellat were; Fe: 206.39-262.38 μg g-1, Cd: 0.26-0.39 μg g-1, Cu:30.26-55.63 μg g-1, Ni: 0.54-0.87 μg g-1, Pb:14.36-21.51 μg g-1, and Zn: 53.52-82.15 μg g-1. In general, the highest metal levels were found in i en e ae ii. Negative biological effects caused by the presence of various toxicants in fish tissues were studied with bacterial lux-biosensors. These assays revealed that the accumulation of genotoxicants, oxidative stressors, and substances causing damage to proteins and membranes mainly occurred in gills and to a smaller extent in liver. i en e ae ii showed the highest accumulation of toxic substances according to the bacterial luxbiosensor assays. |
