英文摘要: Feeding of freshwater cyclopoid copepod Acanthocyclops robustus on zooplankton was examined by a series of feeding experiments during August-September of 1993. Study results showed A. robustus can capture and eat all type items provided from the Stary Haklovsky fishpond, a shallow eutrophic water body near Budejovice City, Czech Republic. Selection by the predator was determined largely by prey body-size and density, but was also affected by prey types. Variable but significant changes in feeding rates were found in various size distribution and concentration of prey types. Percentages of small (80-235-mu-m) and large (445-610-mu-m) prey consumed were 42.47 and 3.85%, respectively. Starvation did not cause statistically significant difference. The feeding on Ceriodaphnia quadrangula showed significant difference between large and small prey. Feeding rate increased with increasing prey concentration.
