Abstract Many dinoflagellate species are bioluminescent, which is one of the anti-predation mechanisms in these species. In addition, experience a wide range salinities ocean. However, effects salinity on their bioluminescence intensity has only been investigated for Here, we explored effect heterotrophic Noctiluca scintillans NSDJ2010 feeding chlorophyte Dunaliella salina , Polykrikos kofoidii PKJH1607 Alexadrium minutum and autotrophic Alexandrium mediterraneum AMYS1807. Moreover, to determine cell volume growth intensity, rate three bioluminescent dinoflagellates were simultaneously investigated. The mean 200-s-integrated (BL) per cell, equivalent total bioluminescence, N. P. A. was significantly affected by increased with increasing from 10 40. results present study suggest that offshore oceanic waters greater than estuarine waters.
