Sažetak
Seasonal variations in abundance and carbon biomass of ciliated protozoa and micrometazoa were studied from May 1998 until November 1999 in the eutrophicated area of Kaštela Bay (middle Adriatic Sea). Ciliates showed peaks in spring and autumn, primarily due to changes in the abundance and biomass of tintinnines, which participated in total ciliate abundance and biomass with 40.48% and 60.02%, respectively. The highest tintinnine density was 4278 ind. l-1, while their average biomass varied from 0.611 to 26.557 μ gC l-1. Maximal average density and biomass of non-loricates were 1430 ind. l-1 and 3.925 mgC l-1, respectively. The micrometazoa community was dominated by copepod nauplii, especially during the summer and autumn. The copepod biomass ranged between 3.47 and 26.75 μ gC l-1. High abundance and biomass values of the investigated zooplankton groups point to an important role of these organisms in the secondary production in the Bay, indicating that they may be 1) a crucial factor in controlling the populations of nano- / pico-phytoplankton and heterotrophic nanoflagellates, and 2) a significant prey for larger micrometazoans.
