In the present study, the qualitative and quantitative changes of zooplankton community were examined on a monthly basis at three stations off the coast of Trabzon, the South- eastern Black Sea from October 2007 to September 2008. A total of 36 samples were collected. The highest value of the abundance of the total zooplankton was recorded in May. Noctiluca scintillans was the most abundant zooplankton with a share of 54% (maximum: 3752,80 ind.m-3 in May). They were followed by Copepoda with 21% (maximum: 551 ind.m-3 in March and Cladocera with 13% (maximum: 680 ind.m-3 in August. Copepoda was present in the sampling throughout the year whereas N. scintillans and Cladocera were dominant for a period of 2-3 months. The annual average abundance of zooplankton was 1116±282 ind.m-3 (55989 ind./m²). In addition temperature as main physical parameter of environment was determined according to the depth.
