The weekly measurement of physico-chemical and biological parameters was done during the spring of 2008 in order to assess the level of eutrophication in the Kotor Bay. Chlorophyll a was used as trophic level indicator and its values varied from minimal 1.00 mg/cubic meter in June on the depth of 10 m to maximal 3.71 mg/cubic meter on the sea surface in May. According to Nixon criteria during investigation period it can be concluded that the area in question is oligotrophic. On the other hand, according to UNEP criteria which are somewhat stricter when the concentration of chlorophyll a is in question, Kotor Bay was mesoeutrophic area.

Zooplankton community analysis was conducted for spring (April - 07) and summer (August - 07) in Boka Kotorska Bay. Analyses included determination of biomass and qualitative composition. Data are given on the number of specimens per cubic meter as well as on the volume organisms. Qualitative composition showed domination Copepoda of zooplanktons groups.

New locations for the distribution of algae C. corniculata (Phaeophyceae) are presented, with a scope to improve scarce knowledge on phytobenthos of the Montenegrian coast. In the Bay of Boka Kotorska this algae is found on 10 locations and on 3 locations, on depth of 3 m and 5 m, measurements of wet weight and length of primary branches are done. Differences between biomass of algae are note between different depths and different seasons, but between different locations there are no significant differences.

This paper presents the concentration of Pb, Cd, Zn, Cu and Ni in the surface sediment samples, determined by EDPXRF. Also, a horizontal distribution of these metals is given for seven investigated sites in the coastal sea of Montenegro, from the entrace to the Bokakotorska Bay to the mouth of the river Bojana. A trend of increase in the concentration of metals with the distance from the coast is noticed in the studied area. The possible causes of this distribution should be sought in the direction of movement of sea currents in the Adriatic Sea as well as the fate of suspended material after entering the river Bojana.

In the present paper it is presented application of Daily Egg Production Method (DEPM) to the anchovy (Engraulis encrasicolus L. 1758) stock in the open part of Montenegrin coast. This article is based on the research done within the frame of AdriaMed Project.
