3. Diet of three cryptobenthic clingfish species and the factors influencing itDomen Trkov, Danijel Ivajnšič, Marcelo Kovačić, Lovrenc Lipej, 2024, izvirni znanstveni članek Povzetek: Cryptobenthic fish are small benthic fish species that normally live in various hiding places. Due to their large numbers, they are very important for energy transfer to higher trophic levels. However, due to their small size and hidden lifestyle, knowledge about them and their ecology, including their diet, is still limited. Using a non-destructive method based on faecal pellets, we investigated the diet of three clingfish species, Lepadogaster lepadogaster, L. candolii, and Apletodon incognitus, in the shallow northern Adriatic Sea. To better understand the results, we studied the fauna of potential prey in the habitats of the fish studied and also took fish specimens to observe their behaviour in the laboratory. The three species feed predominantly on crustaceans, particularly amphipods, copepods, and decapods. The proportion of the different taxa in the diet depends on the species of clingfish, the size of the specimens, and the size of the prey. In addition, the behaviour of the fish, the home range of the specimens, and the availability of food played an important role. The presence of certain crustacean groups in the environment also determines the occurrence of clingfish of different species and sizes.

6. Marine strategy framework directive : Descriptor 2, non - indigenous species delivering solid recommendations for setting threshold values for non-indigenous species pressure on European seasKonstantinos Tsiamis, Ivan Cvitković, Marija Despalatović, Branko Dragičević, Jakov Dulčić, Ana Fortič, Janja Francé, Lovrenc Lipej, Borut Mavrič, Patricija Mozetič, Živana Ninčević Gladan, Martina Orlando-Bonaca, Monika Peterlin, Valentina Pitacco, Domen Trkov, Olja Vidjak, Ante Žuljević, 2021, končno poročilo o rezultatih raziskav Povzetek: Marine Non-Indigenous Species (NIS) are animals and plants introduced accidently or deliberately into the European seas, originating from other seas of the globe. About 800 marine non-indigenous species (NIS) currently occur in the European Union national marine waters, several of which have negative impacts on marine ecosystem services and biodiversity. Under the Marine Strategy Framework Directive (MSFD) Descriptor 2 (D2), EU Member States (MSs) need to consider NIS in their marine management strategies. The Descriptor D2 includes one primary criterion (D2C1: new NIS introductions), and two secondary criteria (D2C2 and D2C3). The D2 implementation is characterized by a number of issues and uncertainties which can be applicable to the Descriptor level (e.g. geographical unit of assessment, assessment period, phytoplanktonic, parasitic, oligohaline NIS, etc.), to the primary criterion D2C1 level (e.g. threshold values, cryptogenic, questionable species, etc), and to the secondary criteria D2C2 and D2C3. The current report tackles these issues and provides practical recommendations aiming at a smoother and more efficient implementation of D2 and its criteria at EU level. They constitute a solid operational output which can result in more comparable D2 assessments among MSs and MSFD regions/subregions. When it comes to the policy-side, the current report calls for a number of different categories of NIS to be reported in D2 assessments, pointing the need for the species to be labelled/categorised appropriately in the MSFD reporting by the MSs. These suggestions are proposed to be communicated to the MSFD Working Group of Good Environmental Status (GES) and subsequently to the Marine Strategy Coordination Group (MSCG) of MSFD. Moreover, they can serve as an input for revising the Art. 8 Guidelines.

7. Occurrence of ribbon fish (Trachipterus trachypterus) In Slovenian waters (Northern Adriatic Sea)Lovrenc Lipej, Domen Trkov, Borut Mavrič, 2018, drugi znanstveni članki Povzetek: On 6th May 2018 a juvenile specimen of ribbon fish (Trachipterus trachypterus) was collected in shallow waters in Izola (Slovenia, northern Adriatic Sea). It measured 403 mm in total length and weighed 37.1 g. In stomach, fragments of seagrasses, pollen cones of pine, petals of terrestrial plant, fragments of terrestrial grass and beetles were found among food remains. The possible causes of this finding in Slovenian waters could be attributed to the ingression of southern Adriatic waters in its northern part. The specimen studied in this paper is the fifth record of this species in the Slovenian part of the Adriatic Sea. The cooperation between ichthyologists and fishermen proved to be crucial for the detection of the ribbon fish and other rare and less-known fish species, as well.

8. First record of the Canestrini’s goby Ninnigobius canestrinii (Ninni, 1883) : a rare and endangered fish species from Slovenian watersDomen Trkov, Ana Fortič, 2023, drugi znanstveni članki Povzetek: The Canestrini’s goby is a small goby endemic to the Adriatic basin, inhabiting brackish and fresh waters. The species is threatened by habitat destruction and pollution. For this reason, the goby is protected in part of its range, while its conservation status in other areas is not yet established. The detailed biogeography of the species should be known so that appropriate conservation measures can be taken. Despite extensive sampling of fish fauna in coastal wetlands, this species has not yet been detected in Slovenia. In this study, the first record of Ninnigobius canestrinii (Ninni, 1883) in Slovenian waters is reported along with a comprehensive review of documented records of the species.

Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).

10. Review of heterobranch molluscs fauna in the Boka Kotorska Bay, MontenegroMilica Jovanović, Vesna Mačić, Domen Trkov, Martina Orlando-Bonaca, Lovrenc Lipej, 2019, pregledni znanstveni članek Povzetek: Heterobranch molluscs fauna in Montenegro has been poorly investigated so far. The aim of the present paper is to improve the knowledge about species diversity of these marine organisms in the Boka Kotorska Bay, specific fjord-like entity in the southern Adriatic Sea. New records of seven heterobranch species were obtained by field surveys in 2017, while three new records were provided by analysing underwater photographs from previous periods. The resulted checklist summarizes the knowledge of the diversity of heterobranchs in the Boka Kotorska Bay from the oldest record in 1967 to the present day, and consists of a total of 62 heterobranch species.
