The mass mortality of the pen shell Pinna nobilis, caused by protozoan parasite Hap-lospridium pinnae sp., is spreading throughout the Mediterranean. Apart of Spain, it has been already observed in Greece, Cyprus, France, Italy, and Tunisia. Before the occur-rence of this event in 2016, we have started implementation of the project “The study, protection and possible breeding of pen shell (Pinna nobilis) in the Boka Kotorska Bay” – PinnaSPOT. The main research area was Boka Kotorska Bay in Montenegro, data ob-tained by the common methodology in Calpe (Alicante) – Spain and Embiez Island – France was compared. Exceptionally high density of P. nobilis on Sv. Nedjelja site, with higher percent of young individuals was observed. We collected 3-year data on larval recruitment and monthly measurements of juvenile’s growth rate. Physiological adaption of specimens on sudden salinity stress was carried out ex situ. All the specimens survived non-invasive experimental treatments and were successfully returned to their natural hab-itats, which gave us valuable experience on transplantation and maintenance of P. nobilis in laboratory conditions as an important step for the rescue in case of emergency. Habitat structure of P. nobilis populations based on oceanographic parameters, sediment re-sus-pension, granulometry, percent of organic matter and covering of Posidonia oceanica and Cymodocea nodosa meadows revealed very specific seasonal variations. Genetic study on tissue samples from Montenegro, Spain, France and Monaco led to the first draft ge-nome of P. nobilis. Data obtained in these various activities focused on pen shell will contribute to general knowledge and protection of this endangered species in southern part of the Adriatic Sea and in case of threat to their survival, will be used as a tool for preparation of the rescue program

Heavy metal concentrations in sediment and fish species from Boka Kotorska Bay
2020
The concentrations of lead, mercury, copper and zinc were determined in sediments and muscle tissues of red mullet (<em>Mullus barbatus</em>) sampled from Boka Kotorska Bay, the Montenegrin coast. The average concentrations of the heavy metals found in sediment samples were: 31.8 ± 7.04 mg/kg for Pb, 0.388 ± 0.056 mg/kg for Hg, 57.7 ± 27.4 mg/kg for Cu and 111 ± 31.1 mg/kg for Zn, dry weight, while the average concentrations of heavy metals in red mullet samples were: 0.045 ± 0.011 mg/kg for Pb, 0.65 ± 0.14 mg/kg for Hg, 0.26 ± 0.04 mg/kg for Cu and 2.39 ± 0.21 mg/kg for Zn, wet-weight. According to sediment quality guidelines, included in the Canadian Environmental Quality Guidelines, only the concentrations of Cu and Hg exceeded the threshold effect levels (TEL). Also, considering USEPA Sediment Quality Guidelines, the sediments were classified as non-polluted (Pb) and moderately polluted (Cu and Zn). Metal concentrations in the red mullet samples in both seasons were ...

Considering that microplastics are widespread in the marine environment, in this study we evaluated the presence, identify distribution, abundance, shape type, and color of microplastics in surface sediment along the Montenegrin coast, on the Adriatic Sea. These preliminary results provide the first published record of microplastics found in the surface sediment of this area and highlight the importance of microplastics as a component of marine debris. We documented the presence of microplastics at all sampling locations. The identification of polymer types was performed using Fourier-transform infrared (FTIR) spectroscopy, whereby the presence of three polymer types became evident: polypropylene (54.5%), polyethylene (9.7%), and acrylate copolymer (2.0%). Another 22.2% of particles were unidentified polymers, and the remaining 11.5% were non-synthetic materials. The most common shape type of microplastics was filaments (55.5%), followed by granules (26.3%), fragments (14.9%), and f...

Sustainability of shellfish aquaculture in Montenegro-perspectives
Veterinarski glasnik, 2022
Shellfish for human consumption is produced in excess of 15 million tons per year, accounting for roughly 14% of global marine aquaculture, with China being the largest producer (89% of world production). However, in the previous two decades, shellfish output in the European Union has been dropping. This review provides information about shellfish aquaculture in Montenegro, in Boka Kotorska Bay, where most farms belong to the group of small farms. Shellfish production in this bay is constantly increasing. Thus, with minor deviations, the production of shellfish increased from 156 tonnes, as was produced in 2012, to 246 tonnes produced in 2020. However, despite the constant growth of production, statistical data indicate that every year a large amount of shellfish is imported, and there is a need for greater production in the country. The shellfish production capacity in Montenegro is still lower than expected, despite the great potential for development. Aquaculture's development potential is in the areas of increasing production, modernising existing farms, automating production, strengthening the competitiveness and efficiency of the sector, introducing new Veterinarski Glasnik 2022, 76 (2), 125-135 126 species, better linking aquaculture with tourism and processing, marine spatial planning, promoting aquaculture products and branding products.

Investigation of the qualitative and quantitative composition of marine bivalve was conducted in the area of the Boka Kotorska Bay during December 2016, on six transects (Krtole, Tunja near Sveti Marko Island, Sveta Nedjelja, Kostanjica–Morinj, Ljuta and Kamp). Sampling was performed with experimental dredge, allowed only for scientific purposes, as its use is prohibited in the Bay (Official Gazette of Montenegro, 47/15). The main goal was to determine the quantitative and qualitative composition of marine bivalve, with reference to commercially important species who present potential candidates for the farming process. A total of 58 marine bivalves were identified from 24 families, but all specimens were presented by empty shells. The highest diversity of families and highest number of species was recorded on the transect Sveta Nedjelja, 21 families and 43 species, while the lowest number of families (10) was recorded on the transect Ljuta, and the lowest number of species (12) was recorded on transect in Krtole. The family Cardiidae stands out as the most numerous, with the species Acanthocardia paucicostata, present on all six transects with the highest number of individuals. The following species were noted as commercially significant: Ostrea edulis, Mytilus galloprovincialis, Mimachlamys varia, Chamelea gallina, Venus verrucosa, Ruditapes decussatus, Cerastoderma edule, Pecten jacobaeus, Pinna nobilis and Arca noae. Pinna nobilis is protected by law in Montenegro, while Teredo navalis is cryptogenic. Analysis of bivalvia assemblages, based on the species composition, between inner and outer part of the Boka Kotorska Bay showed that there were no significant differences (Global R=0.148, p=0.3). The obtained results showed a great diversity of marine bivalves in the Boka Kotorska Bay, which indicates the exceptional potential of the bay for diversification in the mariculture sector.

It is known that fish farming can have a negative impact on marine environment, such as hyper-nutrification and changes in the bottom ecosystem, especially among enclosed areas (e.g. bays) where sea currents are not strong. Integrated multi-trophic aquaculture (IMTA) is recognized as a strategy for control and minimizing the impact of fish farming in the marine environment. IMTA can be defined as cultivation of fed aquaculture species (e.g. fish) associated with other species able to extract organic and/or inorganic substances from seawater (e.g. bivalves). The study of European flat oyster growth in IMTA and monoculture farming was conducted on two separate geographical locations within the Boka Kotorska Bay. Growth was monitored on three different positions: NBL – position near fish cages, NUD – position 100 m removed from the fish cages and SVN – monoculture, every other month during an 18-month experiment (in total nine monitored periods). At the conclusion of the study, all monitored individuals at SVN and NUD positions achieved commercial size (60 mm), while four individuals at NBL site did not. The highest mortality rate was at the NBL position, most probably due to the effects of fouling organisms. Also, the highest mortality rate among all positions was during the third and fourth monitoring period (summer period). The most intense growth of oysters was in spring. Results of ANOVA showed that there were statistically significant differences in growth rate among monitored periods (F=119.321; p<0.001), while Turkey post hoc test showed that the most intense growth was during the first monitored period, and the least intense during the eighth and ninth monitored period. Results of ANOVA also showed that there were statistically significant differences in growth rate among positions (F=7.536; p<0.001), while Turkey post hoc test showed that growth rates on NUD and SVN positions were similar and higher compared to NBL.
The Mediterranean blue mussel Mytilus galloprovincialis (L) was collected from fall 2006 to spring 2007 from five sites along the Montenegrin coastline. Three wild samples were collected from the open sea coastline, and the other two wild samples, were collected from the enclosed Boka Kotorska Bay. The soft tissue of mussels was analyzed for zinc (Zn), copper (Cu), lead (Pb), cadmium (Cd) and arsenic (As). Concentrations of these metals ranged from 160 - 221.1 for Zn, 6.25 -15.25 for Cu, 4.25 - 9.5 for Pb, 1.4 - 2.3 for Cd and 3.7-11.2 for As in mg kg-1 dry weight. Metals were found to be present in samples at different levels, but not in concentrations higher than maximum residual levels prescribed by EU.
Metal pollution determined by pollution indices for sea grass P. oceanica and surface sediments
Archives of Biological Sciences, 2014
Concentrations of Fe, Mn, Cu, Zn, Pb, Ni, Co, As, Co, and Hg in the sea grass Posidonia oceanica and surface sediment samples were determined. Together with P. oceanica, surface sediment samples were collected at eight locations in the major demographic, tourist and port areas along the Montenegrin coast to assess metal pollution. The metal pollution index (MPI) and metal enrichment factor (EF) were calculated and used to evaluate the impact of heavy metals in the surface sediment on P. oceanica. The sediment MPI and EF values were lower than these values in P. oceanica at the same locations. Since the surface sediment contained lower mean concentrations of Zn, Ni, Pb, Cd and Hg, than the sea grass P. oceanic, we concluded that the sea grass absorbed some metals from the seawater column.
