Sažetak
The objective of this study was to determine the structure of phytoplankton and zooplankton in four carp (Cyprinus carpio Linnaeus, 1758) ponds – two ponds with juveniles and two ponds with adult carp. Phytoplankton diversity was similar in all ponds, but differences were found in predominant species and total abundance (from 59.7x106 cells/L to 79.0x106 cells/L). The diatom Aulacoseira pusilla (22% of total cells/L) was the predominant species in one pond with juveniles, while chlorococalean Ankistrodesmus arcuatus (13%) dominated in the second pond with juvenile fish. In general, the well- developed species in all ponds were chlorococcales (genera Ankistrodesmus, Monoraphidium, Plagioselmis, Lemmermania, Pseudodidymocystis and Scenedesmus) with relative abundance from 5 to 22%. Cyanobacteria Microcystis wesenbergii reached high abundance (15%) only in one pond with adult fish. Qualitative analyses of zooplankton revealed significant differences in microcrustacean composition. The most abundant cladoceran species were Chydorus sphaericus (21 and 44%, respectively) and Bosmina longirostris (38 and 33%, respectively), while copepods were dominated by the genera Acanthocyclops (72 and 45%, respectively). Copepodites were abundant in ponds with adult fish, while a larger number of adult copepods were found in a pond with juvenile fish. The results suggest distinct phyto- and zooplankton communities and their potentially important role in carp pond function.
