In 1987-1989 the species composition of phytoplankton, its abundance and chlorophyll concentrations were studied in the irrigation reservoirs Petrova Ves and Prietrz (West Slovakia). Resevoirs were utilized not only for irrigation but also for production of stocking and marketable carps in two-year cycles. The phytoplankton community of both reservoirs is very similar in species composition and development dynamics and is considered to be a typical pond community. Chlorophytes and diatoms represented the largest proportion in both reservoirs. The abundance of phytoplankton and content of chlorophyll in both reservoirs of the study were lower in years of fish stocking than in the year of harvesting marketable fish.
