The dynamics of total numbers of bacteria have been analyzed in the waters of Sevastopol Bay from 1966 to 2007 on the basis of own and literary data. The values ranged between 0.7 and 8.1 × 106 cells·ml-1. Three distinct periods were recognized in the bacterial dynamics: increase in the bacterioplankton numbers from 1966 to 1988; their high variability in 1992 to 2003; their gradual in 2004 – 2007 down to the values observed in late 1970s and early 1980s. The revealed cyclic indicates a high eco
