The influences of dynamic changes of hydrological conditions on the biota of Boka Kotorska Bay [Adriatic sea, Montenegro, Yugoslavia]
1999
Bozovic, M. (Savezno ministarstvo za razvoj, nauku i zivotnu sredinu, Beograd (Yugoslavia))
The main characteristics of catchment area of Boka Kotorska Bay (Adriatic sea, Montenegro, Yugoslavia), are high slope, carstic structure of ground, high precipitation (over 5000 mm a year) and high run-off of rain water. All rainwater is transported trough carstic ground structures quickly appearing in numerous sources along the sea cost or ones located on the bottom of the Bay. The large volume of freshwater which permanently empty into the Bay has the strong influence on the aquatic environment (salinity, temperature, transparency, etc.) and biota (abundance of the species) as it has been observed in the parts of Boka Kotorska Bay (i.e. Morinj and Risan Bays). The abundance and number of species are the good indicator of changes of aquatic environment and hydrological changes as well as of the capability of aquatic organisms to adapt quickly on the severe changes of conditions.

1999
Vukanic, D. | Dutina, M. | Regner, D. | Vuksanovic, N. (Institut za biologiju mora, Kotor (Yugoslavia))
In this paper, some data on long term seasonal investigation of hydrography and plankton are presented. The most important fact is that the whole area is exposed to the impact of the freshwater from numerous sources from the coast and submarine springs in Boka Kotorska Bay, as the impact of rivers Bojana and Drim. Exchange of the intermediate water-masses between Adriatic and Jonian basins is of great importance, too. So, basic ecological data, as well as characteristic phytoplankton and zooplankton groups and species are described.

Regner, D. (Institut za biologiju mora, Kotor (Yugoslavia)) | Vuksanovic, N. | Dutina, M. | Joksimovic, D. | Stjepcevic, B.
Some new results of the monitoring and control of the sea-water quality along the Montenegrin coast of the Adriatic sea, Montenegro (Yugoslavia) are presented. The recent data from summer 1998 are compared with some previous results. So, increasing of temperature mean values and decreasing of salinity and sea-water density were found in comparison with the previous years in the whole investigated area. At the same time, the quality of the sea is growing worse, step by step. Faster changes were found in Boka Kotorska Bay, Montenegro (Yugoslavia) than outside of the bay, in the zone which is exposed to the stronger influence of the open sea. Finally, the most essential conclusion is that the solution of wastewater discharges becomes more and more important, especially in semienclosed Boka Kotorska Bay (Adriatic Sea, Montenegro, Yugoslavia).

2003
Vukanic, V. (Institut za biologiju mora, Kotor (Serbia and Montenegro))
During the analyses of zooplankton and hydrography samples from continuous field research in monthly series during 2002 on three shallow stations (Orahovac, Morinj and near the Institute) and 4 central stations in Boka Kotorska Bay (Adriatic sea, Montenegro (Serbia&Montenegro)), exceptionally dense populations of Penilia avirostris were observed. Presence of this species in refreshed waters during the summer in other parts of Adriatic and Mediterranean, and its designation as an indicator, are reasons for presentation of these gathered results from yearly cycle in Boka Kotorska Bay.

Regner, D. | Vuksanovic, N. | Stjepcevic, B. | Joksimovic, D. (Institut za biologiju mora, Kotor (Serbia and Montenegro))
In this paper, results of seasonal investigations throughout 2002, important for evaluation of the eutrophication and bacterial pollution of the Montenegrin coastal sea were presented. It was established that the difference between warmer and colder periods of the year was highest in the part of the Montenegrin coastal sea exposed to the strongest impact of the open waters of the Southern Adriatic.

Vukanic, D. | Vukanic, V. (Institut za biologiju mora, Kotor (Serbia and Montenegro))
Available data on zooplakton research in Adriatic sea show that coastal and open waters of south Adriatic are the zone of most available and richest area in Adriatic sea. Shallow waters along the shore and the Boka Kotorska Bay are characterized by a monotony of faunistic content, while, by contrast, high values of biomass are caused by abundance of a small number of estuary-neritic species. Open waters of South Adriatic are characterized by holoplankton, while waters of Boka Kotorska Bay are characterized by meroplankton. Zooplankton of open sea shows a high diversity of fauna but a small biomass in part of open water above the geatest depths, and significantly high values of biomass in epipelagic waters above the continental shelf.

2003
Vuksanovic, N. (Institut za biologiju mora, Kotor (Serbia and Montenegro))
Investigations of phytoplankton were done in the shallow Montenegrin coastal sea during the period from June to December, 2002. These investigations were the continuation from the preceding years. The main intention was to establish the impact of eutrophication to the quantity and composition of phytoplankton i.e. to establish the difference between areas in the bay and outside the bay. Like is previous years, the highest quantities of phytoplankton - microphytoplankton above all, were found in the area of the Boka Kotorska Bay (in Kotor Bay), Montenegro (Serbia&Montenegro). In July, 2.1 x 10**6 cells/cubic dm were found with dominant species Leptocylindrus minimus represented with 1.4 x 10**6 cells/cubic dm. In the area outside the Bay of Boka Kotorska, exposed to the impact of the open sea, values were significantly lower. In front of Budva, maximum was 1.7 x 10**5 cells/cubic dm in July. At locality exposed to the influence of the river Bojana (brackish water), similar values were established, except in October when 1.1 x 10**6 cells/cubic dm were found.

Doklestic, O. (Opstina Herceg Novi, Herceg Novi (Serbia and Montenegro)) | Nicolaides, G.
This work presents a short review of the existing situation, nature conditions and recognised facts which are important for the sea- pollution of the oil, and another kind of the spill ship oils, inside of the Boka Bay and in the area of the open Adriatic Sea. The proposed original and innovative action concerns the large scale application of a new technique for a cleaning up waterborne oil spills, based on the magnetic separation method by using the material "CleanMag", an oleophillic, and porous material which also is magnetic with an increased density lower than that of the water.

There are presented the results of investigations carried out in the Kotor Bay (Adriatic Sea), Montenegro (Serbia and Montenegro) during the winter months of 2004. The highest value of microphytoplankton as a greater size-fraction of phytoplankton is found in the surface layer during March (1.4 x 10**7 cells/cubic dm). The main edificator was diatomic species Skeletonema costatum with relative percentage about 100%. Obtained results point out that Kotor Bay belongs to the highest eutrophic or extreme eutrophic area. Similar result is found in the same period twenty years ago.

Eutrophicationn problems in the Kotor bay were studied monthly from September 2003 to August 2004. As a result of nutrient enrichment (directly dependent on human activities), phytoplankton growth was very intensive, reflected by high concentration of chlorophyll a (7.46 mg/cubic m).
