Molluscan shells are an example of a mineral-based biocomposite material, and most studies to date have focused on understanding their biomineralization mechanisms. Meanwhile, large amounts of these shells are produced as waste globally by seafood which is used by other industries as a source of biogenic calcium carbonates. In this study, we propos...

The paper presents list of the non-indigenous species recorded along the south-eastern Adriatic coast (Montenegro). Using all available scientific literature, technical reports as well as personal data we collected 35 species in total. Among this number 12 are fish and 23 are benthic species. Almost all species can be described as established due t...

In this investigation total of 250 individuals of Gilthead sea bream (Sparus aurata Linnaeus, 1758) and 245 individuals of European sea bass (Dicentrarchus labrax Linnaeus, 1758) were sampled on the fish farm “COGIMAR” located in Orahovac (Boka Kotroska Bay). Samples were taken from September 2015 up to January 2016. Concurrently, sampling of ichth...

U ovom istraživanju obrađeno je 520 jedinki brancina (Dicentrarchus labrax Linnaeus, 1758) sa uzgajališta COGIMAR u Bokokotorskom zalivu. Istraživanja su započeta 2014. godine i biće predstavljeni podaci o dužinsko-težinskom odnosu i kondicionom faktoru ove vrste.Totalna dužina (LT) jedinki u uzorku kretala se od 24,3 do 54 cm, sa prosečnom vrednoš...

The purpose of this study is to show the effects of bottom trawling on the benthic assemblages in the south Adriatic Sea as well as to report detailed quantitative and qualitative data on some invertebrate groups of no commercial value that are affected by trawling. Short-term effects of bottom trawling on the soft bottom seafloor were studied on t...

Age, growth, sex, and condition of different populations of the Atlantic horse mackerel, Trachurus trachurus (L.) in the Turkish seas were determined from 300 specimens between November 2010 and March 2011. Fork length and total weight of the specimens ranged from 10.0 to 18.9 cm and from 12.81 to 81.71 g, respectively. Maximum age group was determ...

Mussels are food for humans, but due to their accumulation ability (bio-toxins, heavy metals and bacteria) they may be dangerous for humans, and even lethal. Because of that, continuous monitoring on farms is necessary in order to prevent any negative consequences on human populations. Application of electro-physiological process based on non-invas...

The results of satellite monitoring of oil pollution in the Southeastern Baltic Sea in 2004-2015 are discussed in the paper. Interannual and seasonal variability of oil pollution is investigated. A steady decrease in total oil pollution was observed from 2004 to 2011. After a sharp increase of oil pollution in 2012, oil pollution level has establis...

In this Collective Article on “New Mediterranean Biodiversity Records”, we present additional records of species found in the Mediterranean Sea. These records refer to eight different countries throughout the northern part of the basin, and include 28 species, belonging to five phyla. The findings per country include the following species: Spain: C...

This study was conducted to determine the first maturity size of females of Norway lobster, Nephrops norvegicus (Linnaeus, 1758). Sampling was carried out by commercial trawl in Montenegrin territorial waters (South Adriatic Sea) between summer 2009 and summer 2011 at the depths of 40-350 m. Carapace length of all collected specimen was ranged from...

Results of operational satellite monitoring of oil pollution of the sea surface together with in-situ measurements of the oil products concentration in the water column for the first time allowed to establish relation between the surface pollution originated from ships, and the general characteristics of spatial and temporal distribution of oil pro...

Growth, sex ratio, and reproduction of striped red mullet (Mullus surmuletus L.) were determined from 520 specimens collected in the northwestern Aegean coast of Turkey from September 2009 to July 2010. Total length ranged from 7.7 to 17.0 cm while weight varied between 3.50 and 58.9 g. According to the length-weight relationship, positive allometr...

The Boka Kotorska Bay is located in the south eastern part of the Adriatic Sea (42°31'00"N, 18°46'32"E), and occupies an area of 87.3 km2. The biggest contribution to the qualitative and quantitative analysis of phytoplankton composition of Boka Kotorska gave Vuksanovic (1983; 2000-2006), as well as Drakulovic (2012-2015). There are over 4000 speci...

Natural biotoxins (phycotoxins) are planktonic algae products which they produce to defence against predators. Bivalve shellfish can acummulate large quantities of biotoxins by water filtration. In humans these toxins can cause six syndromes: ASP, AZP, DSP, NSP, PSP and VSP. Detection of biotoxins is carried on HPLC (High-Performance Liquid Chromat...

The paper is devoted to approbation in laboratory and field conditions of a new method of bio-indication of aquatic ecosystem state on the basis of assessment of functional state of freshwater bivalve mollusks by monitoring of their cardiac activity.

A specimen of Siganus luridus was caught with trammel net on 7 September 2014 in Bigova (cape Trašte) (southern Adriatic Sea, Montenegrin coast). This is the fi rst record of this species for Montenegrin coast, and fourth for the Adriatic Sea.

Daily growth rate of juvenile anchovy, Engraulis encrasicolus (Linnaeus, 1758), was estimated in the south-eastern Adriatic Sea. Samples were taken by a commercial beach seine net and the size range of 100 sampled individuals was 5.0-6.8 cm total length. Age was estimated by counting growth increments of sagittal otoliths, which are formed with dai...

Some aspects of the reproductive biology of females of the deep-water pink shrimp, Parapenaeus longirostris (Lucas, 1846) from the Montenegrin shelf (southern Adriatic Sea) were investigated. Sampling was performed on a monthly basis from November 2006 to October 2007. A total of 13 trawl hauls covered a depth range of 40 to 250 m. An estimate of t...

The annual alteration of gonad morphology in sardine (Sardina pilchardus, Walbaum 1792) caught in the period from November 2006 to October 2007 using beach seines in the region of Boka Kotorska Bay (Montenegro, southern Adriatic) was studied. Samples were taken in the middle of each month. Total length of individuals ranged from 8.7 to 14.7 cm and...

Red mullet, Mullus barbatus Linnaeus, 1758, is an economically very important species in trawl fisheries in the Adriatic Sea. Material for analysis was collected from October 2002 until May 2004 with a bottom trawl net from commercial trawlers on the Montenegrin shelf. Mortality of this species was analyzed for the first time in this area, sepa­rat...
