Abstract

       Samples of microzooplankton were collected at six locations in area of the Middle Adriatic. The investigation was performed with M/V "Baldo Kosić" during four seasonal cruises in 1973/74. Samples were collected by 5 liter Van Dorn bottle. For the analyses the samples were concentrated by sedimentation.

        The tintinnids were the most abundant in November, when Codonellopsis schabi extremly dominated. Its average abundance in the Bay of Kaštela was 148290 ind./m3. At locations in Marina Bay and Pelegrin it was relatively unimportant.

       The ciliates Oligotricha were the most abundant in the Bay of Kaštela during July (average 12330 ind./m3). On the contrary their abundance was about 60% lower at the other locations.

        The Sarcodina were represented by Sticholonche zanclea, only in November. In the Bay of Kaštela they were found averaging 6000 ind./m3. At other locations they were not significant.

        Nauplii were the most numerous Metazoa at all locations. The maximum value was noted in July in the Bay of Kaštela (locations 11, 12) averaging 61000 ind./m3 and at other locations averaging 23800 ind./m3.

       Copepodites, adults small copepods and noncopepod metazoans were not important due to the total number of microzooplankton.
