Abstract :The diel changes in the vertical distribution of zooplankton in the southeast Black Sea were described in this study. The zooplankton were sampled using two different sampling methods throughout one day in October 1996 and July 1997 at the same station. The zooplankton counts, the length measurements and biomass estimates showed that the zooplankton in the southeast Black Sea is dominated by small organisms, among which Noctiluca scintillans is the dominant species. In the vertical distribution of zooplankton, three groups were observed in different layers. Calanus euxinus and Pseudocalanus elongatus showed a clear vertical migration pattern. Conventional measurements insert ignore into journalissuearticles values(settling volume, displacement volume and wet weight measurements); were also carried out and the results were compared with the zooplankton counts and biomass values. Among those, abundance of zooplankton correlated well with the wet weight measurements insert ignore into journalissuearticles values(r = 0.473; p
