The paper presents the seasonal overview of horizontal distribution and abundance for the species of genus Oithona in Bokokotorski Bay. Three species have been recorded. Oithona helgolandica and Oithona plumifera have a wide horizontal distribution within the Adriatic Sea, while Oithona nana is a typical euritherm and eurihaline form that occupies shallow and closed coastal areas along the eastern coast of Adriatic. Also presented are seasonal oscillations and quantitative presence of these species in the Copepoda population during 2002.

In this paper we have presented the results of the investigation of phytoplankton carried out in the Hydrosystem DTD (Danube - Tisza - Danube) in Banat region from April 2003 till November 2004. Accordingly, halophilic algae community of eutrophic type has been described. Seasonal distribution and presence of algae taxa in the investigated water varied significantly. The diatoms were mostly represented by periphytic forms in the huge quantities, which was particularly the case with an avalanche of the eutrophic species such as: Bacillaria paradoxa, Anomoeoneis sphaerophora, Nitzschia acicularis, N. palea, Navicula cryptocephala, Fragilaria ulna, Melosira varians, Surirella ovalis, etc. The significant number of Cyclotella meneghiniana during summer and Euglenophyta in autumn revealed high trophic status in some sections of HS DTD.
