In this study, the seasonal distribution of mesozooplankton was investigated between 1999 and 2006 at a station located in the southeastern Black Sea region. A total of 40 cruises were done within the southeastern continental shelf throughout this period in order to collect mesozooplankton samples. A total of 10 mesozooplankton species were identified. The average annual highest abundances of species were 67,770 ind./m^2 in 2000 (Penilia avirostris), 50,048 ind./m^2 in 2001 (Sagitta setosa), 42,143 ind./m^2 in 2006 (Oikopleura dioica), 27,987 ind./m^2 in 2005 (Acartia clausi), 25,792 ind./m^2 in 2001 (Oithona similis), 24,806 ind./m^2 in 2005 (Pseudocalanus elongatus), 12,094 ind./m^2 in …

The effects of temperature, dissolved oxygen, nitrate, phosphate, and chlorophyll-\alpha concentration on the body length and egg production of a cyclopoid copepod, Thermocyclops crassus, and a calanoid, Eudiaptomus drieschi, were evaluated. Sampling was conducted in Yenişehir Lake (Hatay, Turkey) on a monthly basis between May 2003 and April 2004. The results of the present study showed that, among the parameters considered, temperature and chlorophyll-\alpha concentration were the main parameters influencing the body length of T. crassus and E. drieschi in Yenişehir Lake. For E. drieschi, egg production was also affected by chlorophyll-\alpha levels.
