22. Socioeconomic and environmental importance of the fish market and fisheries in SloveniaAlex Mavrič, Andreja Ramšak, Štefan Bojnec, 2021, izvirni znanstveni članek Povzetek: The paper analyses the importance of fisheries and the fish market in Slovenia based on primary information obtained from interviews and secondary data obtained from various sources. The study focuses on the sustainability aspects of fisheries and the fish market in Slovenia, emphasizing socioeconomic factors, problems and anomalies in the market, ecological aspects, and other sustainable development factors as environmental protection and the implementation of sustainable development measures, as well as overfishing and ineffective fisheries management. Most of shortcomings are related to the traceability of fish in the value chain, misleading customers with false information, and price-quality deception. While these findings are country-specific, they have broader implications and highlight opportunities for improving the fisheries and fish market situation in Slovenia and the international trade of fish and fishery products.

23. New evidence of the occurrence of Knoutsodonta Pictoni (Nudibranchia, Onchidorididae) in the Northern AdriaticAna Fortič, Domen Trkov, Lovrenc Lipej, Marco Fantin, Saul Ciriaco, 2021, izvirni znanstveni članek Povzetek: The authors present new data on the recently described nudibranch Knoutsodonta pictoni Furfaro & Trainito, 2017 in the Gulf of Trieste (northern Adriatic Sea). We hereby present the first record of this species in Slovenian territorial waters. A total of 22 specimens of K. pictoni were recorded by diving in the period from 2017 to 2021 at five localities in the Gulf of Trieste. All specimens were found in precoralligenous habitats in the depth range of 5 to 9 m, feeding on the encrusting bryozoan Reptadeonella violacea (Johnston, 1847). Numerous finds indicate that this only recently described and therefore little known nudibranch is much less rare than previously thought.

24. After more than forty-five years a new finding of Cystoseira foeniculacea f. latiramosa in the coastal sea of SloveniaMartina Orlando-Bonaca, Domen Trkov, 2020, izvirni znanstveni članek Povzetek: Canopy-forming macroalgae, especially Cystoseira sensu lato species, create so-called brown algal forests, which are among the most productive habitats in shallow coastal waters. In the Mediterranean Sea these species have been disappearing over the past two decades due to multiple anthropogenic pressures, and are gradually being replaced by smaller and persistent turf-forming algae. A decrease in the number of species and in the cover of canopy-forming taxa (especially Cystoseira s.l. spp.) has been detected over the last ten years also in Slovenian coastal waters. This paper reports a recent finding of Cystoseira foeniculacea f. latiramosa, which was missing from Slovenian marine waters for more than four decades.

25. Marine cryptobenthic fish fauna of Slovenia (northern Adriatic Sea)Domen Trkov, Borut Mavrič, Martina Orlando-Bonaca, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: Cryptobenthic fish fauna constitute one of the less studied fish groups in the Adriatic Sea. As regards Slovenian coastal waters, only few papers dealing with cryptobenthic fish assemblages have been published to date. All the available data about cryptobenthic fish species in the Slovenian sea are presented in this paper, with particular interest in their geographic and depth distribution. Altogether 798 specimens of 11 different species were collected. Thorogobius macrolepis and Chromogobius quadrivittatus were found in Slovenian territorial waters for the first time only recently. The majority of fishes have been recorded using new techniques, associated with SCUBA diving equipment and the use of the narcotic Quinaldine.

26. Occurrence of giant tun, Tonna galea (Linnaeus, 1758) (Gastropoda: Tonnidae) in the marine waters off Slovenia (northern Adriatic Sea)Manja Rogelja, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: On 1st December 2018 a fisherman caught a specimen of the giant tun Tonna galea (Linnaeus, 1758) in the bottom trammel net for flounders, approximately 1 Nm outside the town of Izola. The net was placed on a muddy bottom at 20 m of depth. This is the second record of T. galea in the Slovenian waters (Gulf of Trieste, northern Adriatic Sea). Another specimen (the first one) was previously reported in October 2015 in the waters off Piran. By including T. galea in the checklist of Slovenian marine malacofauna, at least 370 gastropod species were up to date recorded in the Slovenian part of the Adriatic Sea.

27. Biometry and population gender structure of three crab species (Crustacea: Decapoda) from sandy bottom in the northern Adriatic SeaMona Rezaei, Al Vrezec, Borut Mavrič, Lovrenc Lipej, 2019, izvirni znanstveni članek Povzetek: The aim of the study was to investigate the distribution and population structure of three species of crabs (Decapoda: Crustacea), Medorippe lanata, Liocarcinus depurator and Liocarcinus vernalis for their biometric relationships. A total of 1100 specimens of three species were caught from waters off the northern Adriatic Sea in December 2013. Biometric relationships and condition factor (Fulton’s coefficient index) were measured for all the studied species. Size dimorphism was also observed in M. lanata with females showing significantly larger carapace size than males without significant difference in wet weight. The studied species did not differ significantly in the results of the condition index.

28. Hippolyte prideauxiana Leach, 1817 : first record for the northern Adriatic and observations on mimetic colourationRoland Melzer, Martin Heß, Manuel A. Staggl, Tihomir Makovec, Borut Mavrič, 2019, izvirni znanstveni članek Povzetek: We present the first record of Hippolyte prideauxiana Leach, 1816 for the northern Adriatic and the second record for the Adriatic Sea based on seven specimens we found during our faunistic inventory of the marine protected area of the Brijuni National Park, Croatia. Moreover, we give the first description of the appearance of 7 mm-juveniles and discuss the stage-specific traits of the crinoid mimesis of this species.

29. First record of Sergeant major, Abudefduf saxatilis (Linnaeus, 1758) in the Adriatic SeaLovrenc Lipej, Domen Trkov, Domen Stanič, Sara Cernich, Saul Ciriaco, 2019, izvirni znanstveni članek Povzetek: A specimen of Segeant major Abudefduf saxatilis (Linnaeus, 1758) was observed in a shallow rocky area for several weeks in August and September 2019 at Punta Sottile, in waters off Muggia (Gulf of Trieste). The specimen probably entered the Strait of Gibraltar and arrived at northernmost limits of the Adriatic Sea. This is the first record for this species in the Gulf of Trieste and also the Adriatic Sea.
