1. First record of the bryozoan Tricellaria inopinata (dʼHondt & Occhipinti Ambrogi, 1985) from the Slovenian seaAna Fortič, Borut Mavrič, 2018, other scientific articles Abstract: In this paper we present the first record of Tricellaria inopinata d’Hondt & Occhipinti Ambrogi, 1985 for the Slovenian coastal sea. The colonies of this bryozoan were found attached to the mussel shells in the sight of Sečovlje, Strunjan and Debeli rtič mussel cultures from April to October 2018 and in Valdoltra harbour in November 2018. After the introduction into the Lagoon of Venice in the 1980s and its rapid spread throughout the lagoon in the following years, the species was regarded as an invasive taxon for that area and it is highly expected to colonize the whole Northern Adriatic region. The status of T. inopinata and its ecological impact has yet to be determined for the Slovenian coastal sea.

2. First record of the meagre, Argyrosomus regius (Asso, 1801), in Slovenian coastal waters with additional records from the Croatian part of the Adriatic SeaBorut Mavrič, Branko Dragičević, 2018, original scientific article Abstract: One specimen of meagre, Argyrosomus regius (Asso, 1801), was caught by trawling in the waters off Slovenia on 24th November 2016 at the depth of cca. 20 m above sandy-muddy bottom. This is the fi rst record of this species for the Slovenian part of the Adriatic Sea. Due to the fact that there are no wild populations in the Middle and North Adriatic and that remaining wild populations in the Southern Adriatic are scarce and small, the specimen is supposed to be an escapee from one of the mariculture facilities. Additional occurrences of this species from the Croatian part of the Adriatic Sea are reported.

3. Socioeconomic and environmental importance of the fish market and fisheries in SloveniaAlex Mavrič, Andreja Ramšak, Štefan Bojnec, 2021, original scientific article Abstract: 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.

4. The need for innovations to secure the future of artisanal mussel farming in the coastal sea of the Gulf of Trieste (Slovenia)Andreja Ramšak, Tine Bizjak, Uroš Robič, Manca Kovač Viršek, 2024, original scientific article Abstract: Mariculture along the Slovene coastline is mainly mussel culture operated as a family business; in one case, it is combined with sea bass farming. It started in the early 70 s with cultivation of Mediterranean mussels, while today, the two largest producers incorporate the cultivation of Venus clams and oysters as species with higher economic value on the market. Currently, all mussels and clams produced in Slovenia are sold in the Slovenian, Italian, Croatian and French markets. The production of Mediterranean mussels (Mytilus galloprovincialis) has increased steadily, with the main obstacles being a limited area for cultivation, occasional harmful algal blooms, predation by gilthead seabream and flatworms. In addition, more recent summer heatwaves negatively affected mussel production when seawater reached high temperatures at the thermal limits unsuitable for mussel growth. This study aimed to collect first-hand information about the current mussel production technology, processes and needs to identify opportunities for innovations that could benefit the entire sector (increased knowledge, production yield, reduced workload and effort with administrative issues). The study was based on a semi-structured questionnaire with the owners of mussel farms. Analysis of the questionnaire was supplemented with current knowledge from the field and provided comprehensive insight into a small sector of mussel farming along the Slovenian coast and its possible development in the future.
