• The comparative assessment of the integral intensity of bioluminescence, which characterizes the total biomass and number of plankton, in diferent regions of the Black Sea was carried out. The vertical distribution of the bioluminescence intensity of the plankton community and hydrological parameters of the environment was studied by the method of multiple bathyphotometric sounding of the water column using a measuring hydrobiophysical complex. Zones of divergence and convergence, as well as areas of existence of cyclonic and anticyclonic vortex formations afecting the biological productivity of waters, were determined on the basis of satellite measurements of sea level anomalies. For a comparative assessment of the total biomass and the number of hydrobionts in the selected regions, the integral intensity of bioluminescence of hydrobionts (IIBH) was calculated, which can be the basis for assessing the fshery production potential. It is shown that the IIBH in the summer is infuenced by sufciently high temperatures of the top mixed layer, the depth of the region, the thermohaline structure of water and the nature of circulation processes. The highest IIBH was observed at stations located on the SouthWestern shelf of Crimea
