“…By comparing the research with other Mediterranean areas, and taking into account the limitations of the investigated area -the very shallow waters and a small number of stations -it can be concluded that the general diversity of ichthyoplankton was high, although the spawning intensity was very low during the autumn and winter periods. In the Mar Menor lagoon in south-east Spain, a study of the qualitative and quantitative composition of ichthyoplankton at 20 positions during monthly sampling showed the presence of (Mandić et al, 2014). In the harbour area of Porto Montenegro (Boka Kotorska Bay, south Adriatic Sea) a similar diversity of ichthyoplankton species was recorded (Pestorić et al, 2018).…”

Plankton (ichthyo, zoo and phyto) communities were studied in the temperate shallow waters of the Port of Bar, one of the main cargo ports on the south-eastern Adriatic coast. Sampling was undertaken in February, April, June and October 2015 at 12 stations using the BALMAS Port Baseline Survey protocol. The research was conducted to determine the presence of invasive and potentially toxic plankton species in the port.The most dominant species of ichthyoplankton were eggs and larvae of families Engraulidae, Bothidae and Sparidae with a dominance of Engraulis encrasicolus, Arnoglossus laterna and Diplodus annularis. In addition to ichthyoplankton, sampling of phyto and zooplankton was performed to estimate the abundance and diversity of species.The most numerous zooplankton species throughout investigated period were Penilia avirostris, Euterpina acutifrons, Oithona nana, Acartia clausi, Centropages kroyeri, Paracalanus parvus, Oncaeidae and larvae of Bivalvia. One very unusual occurrence was the spawning of parrotfish Sparisoma cretense (Linnaeus, 1758), a species with Atlantic origin and tropical affinities, whose presence throughout the Mediterranean has shown an increasing trend over the last decade. The most dominant species of phytoplankton were the diatoms Chaetoceros affinis and Chaetoceros spp., Asterionellopsis glacialis, Pseudo-nitzschia spp., Thalassionema nitzschioides, and dinoflagellates Gymnodinium spp. and Prorocentrum triestinum. The potentially toxic species from genus Pseudo- nitzschia reached an abundance of 104 cells L-1. Toxic dinoflagellates Prorocentrum cordatum and P. micans reached values of 103 cells L-1.Although there were no HAOP species found during the survey, presence of several potentially toxic and toxic phytoplankton species whose impact is not sufficiently known indicates the necessity of introduction of regular monitoring activities and definition of preventive protection measures.

“…The bathymetry decreases rapidly up to a depth of 40 m in the largest part of the basin, the average depth and the maximum depth are 27.3 m and 60 m, respectively. The largest and narrowest widths of the bay are respectively 7 km and 0.3 km [32][33][34]. Numerous fresh water inputs characterize the bay, such as submarine springs, precipitations and rivers.…”

“…One of the most frequent wind conditions for this area is Bora, a strong katabatic wind which flows from the first quadrant. Bora is more frequent in winter time, and it can last for 3-7 days [33,34]. Because of the mountains surrounding the bay, the fetch is small, preventing the generation of significant waves [32]; for this reason, we neglect the effect of waves on sea current and oil slick simulations.…”

A major threat for marine and coastal environment comes from oil spill accidents. Such events have a great impact on both the ecosystem and on the economy, and the risk increases over time due to increasing ship traffic in many sensitive areas. In recent years, numerical simulation of oil spills has become an affordable tool for the analysis of the risk and for the preparation of contingency plans. However, in coastal areas, the complexity of the bathymetry and of the orography requires an adequate resolution of sea and wind flows. For this reason, we present, to the best of the author’s knowledge, the first study on the subject adopting Large Eddy Simulations for both the low-atmosphere and sea dynamics in order to provide highly-resolved marine surface current and wind stress to the oil slick model, within a one-way coupling procedure. Such approach is applied to the relevant case of Kotor Bay (UNESCO heritage since 1979), in Montenegro, which is a semi-closed basin surrounded by mountains that is subject to an intense ship traffic for touristic purposes. Oil spill spots are tracked along ship paths, in two wind scenarios.

“…Sardine and anchovy fisheries using beach seine nets have been traditionally present in this region for centuries (ĐUROVIĆ et al, 2012;PEŠIĆ et al, 2017). This type of fisheries targets mostly juvenile part of population (PEŠIĆ et al, 2010) as the Boka Kotorska Bay represents the natural spawning and nursery area of anchovy (MERKER & VUJOŠEVIĆ, 1972;MANDIĆ et al, 2011;MANDIĆ et al, 2013;MANDIĆ et al, 2015;MANDIĆ et al, 2017).…”

The annual alteration of gonad morphology in anchovy, Engraulis encrasicolus (Linnaeus,1758), caught in the period from July 2006 to June 2007 using beach seines in the region of Boka Kotorska Bay (Montenegro, southern Adriatic) was studied. Samples were taken each month. Total length of individuals ranged from 6.6 to 12.2 cm, while weight ranged from 1.58 to 11.27 g, Their ovaries were extracted and weighed, and a piece of female gonad tissue was sampled for histological analysis. The length–weight relationship of all anchovy specimens was described by the equation: \(W = 0.0032\) \(L_T^3.2537; (r^2 = 0.9528)\). The lowest GSI values were found in November and remained at low levels until April, which corresponded to the gonad rest stage. The GSI increased gradually during April and May, which coincides with the begining of spawning period. Although primary oocytes (stage I) were present during all months, their percentage increased from October and was the highest during the winter months (November-March 100%). Mature cells, stage IV, were present during April – October period, with highest value in May when they comprised 12.3% of total oocyte number. An increase in the percentage of oocytes in the yolk vesicle (II) and yolk (III) stages occurred in April, remaining almost unchanged until October. Smallest average oocyte size was noticed in period November – February with an average of 59.69 μm, while greatest size was recorded in April 2007, 185.84 μm.
