This study critically revises the protection status of C. connivens in the countries around the Baltic Sea, as well as its status on the red lists of endangered plant species (including the HELCOM Red List). The first reports on the presence of C. connivens in the Baltic Sea area were published in the aftermath of Carl Baenitz’s talks given in the early 1870s. Already then, the scientific community was well aware of the fact that C. connivens had been introduced as a ballast plant to the known Baltic areas of occurrence – the first known record of the species is from 1829. Since Poland is the only country where C. connivens is protected, the historical and contemporary distribution of this charophyte in the Polish coastal waters is presented against the background of the available historical and recent records of the species in the Baltic Sea. Recent reports from the second half of the 20th century and the beginning of the 21st century have confirmed a fairly common occurrence of C. connivens in Estonia, Sweden and Poland. This species still occurs on the German coast and has also been reported from Finland (the Åland archipelago). In recent decades, however, the species was considered rare in the Baltic Sea area. In Poland, C. connivens was even classified as extinct, despite earlier data on its occurrence in the Vistula Lagoon in the 1970s, where it was rediscovered in 2011. It was also found in the Szczecin Lagoon a year later. Both localities well suit Luther’s pattern of C. connivens occurrence in areas with intensive shipping and ballast discharge operations in historical times. Based on this in-depth revision of historical and current distribution, it is postulated that C. connivens, as non-indigenous, should not be red-listed in the Baltic Sea area, following the example of Finland. Moreover, its legal status in Poland of a strictly protected species should be reconsidered.

Herewith, we report on the second finding of N. davidi in fresh waters of Europe and the first discovery of that species both in Poland and in Central Europe. The species was found in samples collected in 2003, 2013 and 2017 in the thermally polluted canal connected to the River Oder, south of Gryfino, in the vicinity of the Dolna Odra Power Plant. The taxonomic identity of the collected shrimp was confirmed by the standard DNA barcoding procedure, using a 610 bp-long fragment of cytochrome oxidase I (COI). The findings spanning more than a decade suggest that N. davidi may have established a self-reproducing population at this site. Following the finding of Atyaephyra desmarestii (Millet, 1831) in 2000, Neocaridina davidi is the second freshwater shrimp species found in the River Oder and in Poland.

Their role is to provide protection to rare and/or endangered species, protect entire particularly valuable communities and their habitats, serve as a reference in studies on changes in the marine environment, and yield potential benefits for fisheries. Although MPA have been established in various marine areas, most of them are situated in the near-shore zone. Some MPA have not lived up to expectations. Their failure could have resulted from unsuitable location, operation of uncontrollable external factors, inadequate knowledge of the ecology of an area granted protection or a conflict between conservation needs and economic and social goals of stakeholders in an area. However, in many cases, MPA have proven to be an efficient tool in the protection, conservation, and revitalisation of living marine resources. Established and functioning in a framework of an appropriate legal system and cooperation of various groups of users, MPA have the potential of preventing habitat degradation, ameliorate local effects of overfishing, and reinforcing the resistance of marine ecosystems to global climate changes and human population increase. MPA are an answer to the need for conserving the richness of marine species and ecosystems, both those exposed to direct effects of activities within the coastal zone and those that, although remote from the shore, are nevertheless affected by anthropogenic pressure.

The highest density (506 ind./m2) recorded in muddy sediments off the River Świna mouth, even exeeeded that of Nereis diversicolor. Marenzelleria viridis was also abundant (more than 200 ind./m2) off Międzyzdroje and east of the River Dziwna mouth. The disitribution of this mezohaline species points to its preference for finer sediments (muddy sand and mud). The worm has been reported from the North Sea estuaries since 1983. As there was no M. viridis in the Pomeranian Bay in 1984 in contrast to its quite wide distribution in 1988, it is suggested that the polychtete was introduced into Polish waters in 1985 or 1986. Its presence in the vicinity of large North Sea and Baltic harbours seems to indictate man mediated dispersal of the species in European waters.

The inventories are based on the initial assessment of the MSFD (2012) and the updated data of the European Alien Species Information Network, in collaboration with NIS experts appointed by the MSs. The analysis revealed that a large number of NIS was not reported from the initial assessments. Moreover, several NIS initially listed are currently considered as native in Europe or were proven to be historical misreportings. The refined baseline inventories constitute a milestone for the MSFD Descriptor 2 implementation, providing an improved basis for reporting new NIS introductions, facilitating the MSFD D2 assessment. In addition, the inventories can help MSs in the establishment of monitoring systems of targeted NIS, and foster cooperation on monitoring of NIS across or within shared marine subregions.

The workshop was organised by the Joint Research Centre (JRC), in collaboration with representatives of the Regional Sea Conventions (RSCs), under the MSFD Descriptor 2 Core Group, in the context of the MSFD Common Implementation Strategy Good Environmental Status Working Group. The participants to the workshop included academic and public authorities’ experts on MSFD NIS, RSCs representatives, the European Environment Agency (EEA), and Commission services. The workshop enabled sharing information on the state-of-the-art approaches on monitoring and assessment of D2C1 within Regional Seas and on the application of the time series analysis as a follow-up to Tsiamis et al. (2021) recommendations for setting threshold values. The discussion focused on ensuring comparability of approaches, how to account for uncertainties, and on areas for improvement. It was acknowledged that activities of RSCs are instrumental in coordinating the science and management of marine NIS. The various levels of monitoring across the North-East Atlantic Ocean, the Mediterranean Sea, the Baltic Sea and the EU Countries explain different methodological approaches for setting thresholds, while the limited monitoring restrict the application of these methodologies in the Black Sea. The workshop identified four main areas for improvements: i) establishment of acknowledged baselines for NIS introductions, ii) make further progress in monitoring and analysis methods, iii) agree on thresholds for new NIS introductions and, iv) ensure coherence and consistency between national and regional reports. The JRC will seek for opportunities to discuss and advance on identified areas for improvement with the MSFD national appointed NIS experts The MSFD Descriptor 2 (D2) Core Group will contribute to the discussions.

About 800 marine non-indigenous species (NIS) currently occurin 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 toconsider NIS in their marine management strategies. The Descriptor D2 includes one primary criterion (D2C1: new NIS introductions), and two secondary criteria (D2C2and D2C3). The D2 implementation is characterized by a number of issues and uncertaintieswhich 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 whichcan 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 WorkingnGroup 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.

The introduction to the research conducted in the Laboratory of Identification Technologies of the Institute is a description of fishing gears used on the Baltic Sea and introduction to radio identification technologies (RFID). As part of the project, the Institute dealt with eveloping a solution that would allow marking all fishing gears available and used on the Baltic Sea. In the course of the works, ready-made solutions on the market were verified, enabling the marking of gears used in difficult conditions (up to 100 m below sea level) in connection with existing net elements (floats of different types and sizes), however their cost had a significant impact on the price of fishing gears. As a result of these arrangements, in consultation with project partners and experts cooperating with the project team, Identification Technology Laboratory committed to develop prototypes enabling mass marking of fishing gears while maintaining a low cost of this solution. In further laboratory work, the aforementioned prototypes were developed (both 3D projects as well as physical implementations of these projects using various techniques - 3D printing or polyurethane foam molding). Prepared prototypes were then subjected to laboratory tests and after their positive results, also sea trials, in real environment and most importantly in real fishing processes (both with the use of gillnets and trawl nets). The obtained results confirmed the resistance of prototypes to unfavorable working conditions and the possibility of keeping inventories of fishing nets continuously, during the implementation of fishing processes (during casting or pulling out the nets and during operations in the port). As a result of the works carried out, solutions were proposed that were accepted by the assessment of the project team for the mass implementation and recommendation of appropriate legal solutions. The method of identification of the owner of a given fishing gear remains an open question, and as a basis, the project team proposed using global identifiers and standardization compliant with GS1 standards (e.g. GRAI or GIAI identifier developed on their basis in cooperation with the GS1 organization). The result of the project are both 3D prototype projects, prototypes made in the project, as well as this report constituting both the technical documentation of the proposed solution as well as a description of the research and development works carried out.
