Ballast water is recognized as a major vector for the transfer of Harmful Aquatic Organisms and Pathogens (HAOP) and a source of sea pollution that negatively affects the environment and human health. Therefore, the International Maritime Organization (IMO) adopted the International Convention for the Control and Management of Ship’s Ballast Water...
An overview of the negative effects of the COVID-19 pandemic on the mariculture industry of the republic of Croatia is provided. An initial online survey was circulated early after the onset of the pandemic and a follow-up field survey was performed a year into the pandemic. The surveyed companies varied in size (micro to medium enterprises), locat...
Samples of the European eel, Anguilla anguilla from two different habitats in the River Neretva estuary region were analysed using two different traditional fishery gear, in the period from 2016 to 2019. The monthly eel catches in ten traditional fyke nets in Parila lagoon varied from 4.4 to 12.7 kg (±2.45 kg) in 2016 and 2.4 to 9.6 kg (±2.01 kg) i...
A comparative study of the two northeastern ports of the Adriatic Sea indicated that the port of Rijeka is microbiologically more loaded than the port of Pula and posing a greater threat to other ports through a potential transfer of pathogens by ballast water. Fecal indicator bacteria, Escherichia coli and intestinal enterococci, were investigated...
The COVID-19 global pandemic has had severe, unpredictable and synchronous impacts on all levels of perishable food supply chains (PFSC), across multiple sectors and spatial scales. Aquaculture plays a vital and rapidly expanding role in food security, in some cases overtaking wild caught fisheries in the production of high-quality animal protein i...
A 3D numerical model of sea circulation and transport of larvae introduced at a fixed position of the port terminal due to discharges of ballast water from ship tanks for the Port of Ploče waters was established. The model larvae particles are not passive but have sensory capacity to recognize environmental conditions and cognitive reaction regardi...
The rapid, global spread of COVID-19, and the measures intended to limit or slow its propagation, are having major impacts on diverse sectors of society. Notably, these impacts are occurring in the context of other anthropogenic-driven threats including global climate change. Both anthropogenic stressors and the COVID-19 pandemic represent signific...
An experimental recirculating aquaculture system was constructed under ambient seawater conditions to compare microbial community diversity of nitrifying and denitrifying biofilters that were derived from a commercial inoculum used for aquarium applications.
Next generation sequencing revealed distinct and diverse microbial communities in samples...
Vessels, specifically ballast water and hull fouling, are a major vector for the introduction of non-indigenous species (NIS) in European seas. The Mediterranean is one of the world's marine regions where their invasion is heaviest. The shallow Adriatic basin is a highly sensitive area that is already experiencing its consequences. The secondary sp...
The objective of this study was to determine whether the use of the electromagnetic field (EMF) of 50 Hz frequency and magnetic induction of 0.25 T could make for successful inactivation of a phytoplankton species, namely, marine microalgae Tetraselmis suecica and two bacteria strains; Escherichia coli and Enterococcus faecalis. A number of laborat...
The zooplankton community was analyzed in ten Adriatic ports as part of the port biological baseline surveys carried out within the framework of the BALMAS project. We provide the first inventory of resident zooplankton taxa and five detected non-indigenous zooplankton species (NIS), and their spatial and seasonal distribution patterns. Copepoda an...
Ports are subject to a variety of anthropogenic impacts, and there is mounting evidence of faecal contamination through several routes. Yet, little is known about pollution in ports by faecal indicator bacteria (FIB). FIB spatio-temporal dynamics were assessed in 12 ports of the Adriatic Sea, a semi-enclosed basin under strong anthropogenic pressur...
Laboratory experiments were carried out to determine the effects of an integrated ballast water treatment system on the viability of test species of phytoplankton (Tetraselmis suecica) and zooplankton (Artemia salina cysts and nauplii). The effects of two components of the treatment system were tested: cyclonic separation in the hydrocyclone (HC) a...
The reproductive cycle of the dog cockle, Glycymeris nummaria (Glycymerididae), was studied using specimens collected monthly from Mali Ston Bay, southeastern Adriatic Sea over the period from January to December 2010. We analysed sex ratios, gonad developmental stages, and oocyte diameters using standard histological techniques. There were no diff...
The Croatian part of the Adriatic Sea covers more than 35% of the total Croatian territory, which means that monitoring changes in marine ecosystems and the conservation of biodiversity are of great importance. Following global changes, Croatia is experiencing increasing problems due to the introduction of new species that include aliens (due to aq...
Fine spatial and temporal phytoplankton variability in Mali Ston Bay has been observed for the first time based on physicochemical properties and small herbivorous zooplankton. Extensive year-through research was conducted during 2002 at Usko station which is traditionally an area of intensive shellfish farming. The Neretva River inflow, submarine...
The paper presents data on the structure of total zooplankton according to comparison of microfraction and mesofraction of quantitatively important zooplankton groups in the Jabuka Pit region. Research work was carried out during six cruises from 1986 to 1992 in the framework of the Adriatic Scientific Coordinating Programme (ASCOP). The samples we...
The introduction of non indigenous species has been recognised as a serious threat to global biodiversity. Several vectors of the introduction in marine ecosystems are known; the most significant being aquaculture activities and shipping, i.e. hull fouling and ballast water. This paper describes testing of the ballast water treatment system on boar...
A pilot-plant study was conducted in the Republic of Croatia to determine the applicability of ozonation for inactivation of non-indigenous species and to provide necessary information regarding use of ozone as a ballast water treatment option. Nauplii of the brine shrimp Artemia salina were used as model organisms to investigate the efficacy of oz...
Alohtone vrste prenose se diljem svijeta različitim sredstvima, najčešće u obraštaju ili balastnim tankovima brodova te akvakulturnim djelatnostima. Unos stranih vrsta može imati štetne učinke na ekosustav, gospodarstvo ili ljudsko zdravlje. Opasne vrste i patogeni prenose se većinom u vodenom balastu pa bi njihovo pravodobno otkrivanje moglo sprij...
Sponges are the simplest multicellular animals. Farming of sponges is facilitated by their asexual reproduction and great ability of regeneration. Farming of filter-feeding sponges is environment friendly, and it can positively influence on environmental impact of other aquaculture activities. Natural populations of sponges in Mediterranean Sea are...
This paper regards legal instruments for protection of the Mediterranean sea, implementation of the IMO Convenction for ballast water and sediments in Croatia and its possible usefulnes in order to preserve the Adriatic sea, but also the possibilities and methods for proclamation of the Adriatic sea as the Particulary Sensitive Sea Area (PSSA).

Interdisciplinary research and development of measures for reduction of the potential harmful effects of the introduction of non-indigenous and harmful species by ship’s ballast water on biodiversity and marine ecosystems.
Collect the data for the effective protection of port areas from the introduction and dispersal of foreign and harmful species by ship’s ballast water. The goal would be implemented by the work of the team of experts in marine biology, civil engineering, sanitary engineering and nautical science and transport through the following steps:
- representation of sea circulation in the ports of Ploče and Rijeka based on a numerical model;
- listing identified species of pathogens, phytoplankton and zooplankton in the ports of Ploče and Rijeka with the categorization of harmful species (toxic/foreign/invasive foreign species);
- review of the dynamics of the dispersal of planktonic species within the ports of Ploče and Rijeka, and towards the open waters of the Adriatic;
- investigating the influence of abiotic factors and meteorological conditions on pathogens in the ports of Ploče and Rijeka
Latest research results using nanotechnology-based methods and laser-based spectroscopy reveal amazing facets and properties of waste biomaterials from aquaculture sector and seafood industry and their potential for blue bioeconomy. Turning a threat into new opportunity is demonstrated by considering an invasive crab species, which is otherwise generating a significant negative impact on aquaculture and ecosystem sustainability. For a scientist working in advanced materials field, a crab shell is a tridimensional highly ordered natural nano-architecture which is yet challenging for replication in any nanotechnology-based fabrication protocol. Such nano-architectures are increasingly required in innovative research fields like nanobiophotonics, nanomedicine, regenerative medicine, bio-sensing and others. We further demonstrate how the translational research could turn biogenic wasted materials in added-value by-products such as smart materials for solutions loading and slow delivery, selective absorbents, smart bio-fertilizers or photonic materials.The project starts with residual materials of aquatic origin (blue crab Callinectes sapidus shells) and demonstrates that they can become new added-value by-products with proven properties and potential uses according to the concepts of circular economy. In conclusion, the pivotal role of scientific research results dissemination, education and communication along with the built synergies across sectors is demonstrated as an innovation speeder of Blue Growth.
