Shrimp farming increases the nutrients, especially nitrogen in the water resources reducing water quality. This study was conducted to evaluate the nitrogen dynamics in white shrimp (Litopenaeus vannamei) farms and the role of artificial lagoon (24 ha) in reducing nitrogen levels in Gomishan coastal wetland, the eastern Caspian Sea. The results indicated that at the end of the 4-month breeding period, the amounts of nitrogen and phosphorus introduced into Gomishan wetland were calculated as to 220.157 and 39 tons, respectively in a breeding area covering 830 hectares. Nitrogen values (based on nitrate) calculated based on the relationship between the basin and the discharge of the outlet channel of the site at the time of complete emptying of the farms, were calculated to be approximately 121.8 tons per breeding time that it had an important role in eliminating about 45% of nutrient pollution and reducing the concentration of dissolved nitrogen. Moreover, nitrogen isotopic trace was observed in shrimp samples, in similar levels in the samples of both shrimp pond and lagoon, which emphasizes the role of feeding from natural food, especially benthic fauna. Overall, due to the decline of Caspian Sea water level, Gomishan coastal wetland is drying, and the output of shrimp farms is currenly the only source supplying water for the wetland. Hence, appropriate management strategies could minimize the amounts of nutrients into the natural water whilst aiding wetland’s survaival.

- Abstract
The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced species are likely to pose an elevated risk of impact to native species and ecosystems. To inform policy, stakeholders and management decisions on global threats to aquatic ecosystems, 195 assessors representing 120 risk assessment areas across all six inhabited continents screened 819 non-native species from 15 groups of aquatic organisms (freshwater, brackish, marine plants and animals) using the Aquatic Species Invasiveness Screening Kit. This multi-lingual decision-support tool for the risk screening of aquatic organisms provides assessors with risk scores for a species under current and future climate change conditions that, following a statistically based calibration, permits the accurate classification of species into high-, medium- and low-risk categories under current and predicted climate conditions. The 1730 screenings undertaken encompassed wide geographical areas (regions, political entities, parts thereof, water bodies, river basins, lake drainage basins, and marine regions), which permitted thresholds to be identified for almost all aquatic organismal groups screened as well as for tropical, temperate and continental climate classes, and for tropical and temperate marine ecoregions. In total, 33 species were identified as posing a ‘very high risk’ of being or becoming invasive, and the scores of several of these species under current climate increased under future climate conditions, primarily due to their wide thermal tolerances. The risk thresholds determined for taxonomic groups and climate zones provide a basis against which area-specific or climate-based calibrated thresholds may be interpreted. In turn, the risk rankings help decision-makers identify which species require an immediate ‘rapid’ management action (e.g. eradication, control) to avoid or mitigate adverse impacts, which require a full risk assessment, and which are to be r

- Abstract
The goal of the ICES Working Group on the Introduction and Transfers of Marine Organisms (WGITMO) is to contribute to the ICES vision and mission by addressing specific science objectives related to the introduction, spread and impacts of non-indigenous marine species (NIS). The expert working group provides information and advice on the impacts of human activities (e.g. pressures caused by invasive species, litter, aquaculture, biofouling) on marine ecosystems including the Arctic. The Terms of Reference include annual national reporting on NIS detections and research, climate change impact on the spread of NIS, the risk and impacts of NIS, vectors of spread of NIS including biofouling, marine debris and aquaculture. This report summarizes the key findings and outcomes from the 2020–2022 term. A joint meeting in (2020) with WGBOSV [Ballast Water and Other Ship Vectors] and WGHABD [Harmful Algal Bloom Dynamics] was held to discuss scientific issues of joint interest including climate change in the Arctic environment, and early detection of and response to species through the use of innovative molecular tools. The discussion on molecular tools was used by the groups to develop the framework for a targeted Molecular Tools workshop in conjunction with at the International Conference for Marine Bioinvasions (ICMB) in May 2023. National activities were presented and discussed from over 20 countries each year. Common themes included, new species introduction and monitoring, recent activities on traditional and innovative methods for detection and surveillance (including molecular tools). Science highlights include the submission of the ICES biofouling viewpoint to the International Maritime Organization (IMO) regarding biofouling guidelines, development and publication of a global scale NIS screening tool, and publication of a global review of NIS trends over 50 years.

- Abstract
The aim of the Workshop on Stickleback and Round Goby in the Baltic Sea (WKSTARGATE) was to update, summarize and synthesize the current knowledge of both species with respect to their ecology and potential use in fisheries. Ongoing projects were presented in the mornings of the first two days to inform participants about current research in the respective countries (Annex 5). The group discussed ecological aspects that are relevant to fisheries, such as distribution and abundances, feeding ecology and behaviour. So far, no dedicated monitoring exists for either of the species. However, the Baltic International Acoustic Survey (BIAS), coordinated by ICES, has been used to estimate abundances and biomasses of pelagic stickleback in offshore areas across the Baltic, while the availability and quality of coastal data differs between countries, but is generally scarce. Even less current abundance information is available for round goby. It is only available for areas where it is already commercially exploited like Latvia. Most studies on the ecological impact of these species focus on trophic interactions, and its resulting competition. It became clear, that these ecological impacts depend on the abundance of the species and that the effects therefore vary on a temporal and spatial scale. Estimating the ecological impact of a stickleback or round goby fishery is therefore very speculative without reliable abundance data, why the group decided to describe the known impact of the species on the ecosystem. Landings of round goby increased significantly in Latvia during the last years, while stickleback landings decreased over the last five decades but most recently show a slight increase. A targeted round goby fishery exists in Latvian waters, while the stickleback is solely taken as bycatch in all Baltic countries. Both fisheries are currently unmanaged and, with the exception of round goby fishery in Latvia, unregulated. In Latvia the round goby fishery

- Abstract
A measure proven successful in mitigating harbor porpoise bycatch, is the use of acoustic deterrents, i.e., pingers. However, most pingers are audible to seals. This may lead to seals associating pinger sounds with easily accessible food, leading to increased depredation, damage, and bycatch. In this study we tested if an experimental pinger, emitting sounds over 30 hr ON/OFF cycles, with low frequency components potentially audible to seals only at close distances, would effectively deter harbor porpoises. The porpoise response was measured by logging echolocation clicks, using C-POD click detectors, moored at different distances from the pinger. In addition, we calculated the theoretical pinger detection range for seals. Results showed that the pinger had a significant negative effect on the porpoise click activity logged at 0 m and 100 m distance but not at 400 m from the pinger. During pinger ON periods, we found no significant increase in echolocation over consecutive days of the study, suggesting no habituation to pinger sounds. Our theoretical detection distances indicate that seals can only detect the pinger at close distances, preventing seals from using this pinger as a "dinner bell.", Funding Agencies|Brita och Sven Rahms Stiftelse; Gyllenstiernska Krapperup Stiftelse; Havs-och Vattenmyndigheten

- Abstract
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 MSsand 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.

Ecology - Abstract
Syftet med denna rapport är att beskriva kunskapsläget om och betydelsen av de viktigaste påverkansfaktorerna för fisk i svenska marina vatten för att stödja uppdateringen av åtgärdsprogrammet inom havsmiljödirektivet 2021. Havsmiljödirektivets mål är att uppnå eller upprätthålla god miljöstatus i havsmiljöerna. För ekosystemkomponenter som fisk där status är otillfredsställande krävs åtgärder för att nå målen och en påverkansanalys kan bidra med kunskap till förvaltningens arbete med att rikta och prioritera åtgärder. Sammanställningen som presenteras i denna rapport är uppdelad på de två övergripande svenska bedömningsområdena inom havsmiljödirektivet, Nordsjön och Östersjön, samt gör en uppdelning på kust och utsjö vad gäller påverkansfaktorer och deras koppling till fiskfaunan. I rapporten presenteras vilket stöd för påverkan på fisk det fanns i litteraturen fram till hösten 2019 (där inget annat anges) uppdelat på faktorerna fiske, klimat, övergödning, habitatpåverkan och födovävsinteraktioner. Dessutom redovisas översiktligt betydelsen av andra påverkansfaktorer som miljögifter, läkemedelsrester, mikroplaster och marint skräp, undervattensbuller, vitaminbrist, samt parasiter och sjukdomar, områden där kunskapen är mer begränsad. En kvalitativ syntes av resultaten visar att flera faktorer sannolikt har stor påverkan på fisk i kust och utsjö-ekosystemen såväl i Östersjön som i Nordsjön. Dessa faktorer utgör en kombination av förändrade födovävsinteraktioner, samt direkt och indirekt mänsklig påverkan. Direkt påverkan från fiske på målarter och bifångstarter är av betydelse i alla förvaltningsområden och habitat. Möjligen är antalet betydelsefulla påverkansfaktorer något lägre i Nordsjön (framförallt i utsjön), jämfört med Östersjön. Samtidigt verkar det råda en större kunskapsbrist kring annan påverkan i Nordsjön där fiske varit den dominerande påverkan. Betydelsen av klimat, övergödning och habitatförlust är påtaglig i båda förvaltningsområdena. Det råder dock kunskapsbrist om betydelsen av klimat på beståndens status i Nordsjöns utsjö, samt betydelsen av födovävsinteraktioner i alla områden och habitat. Det finns även en kunskapsbrist om hur födovävsinteraktioner kopplade till ökande populationer av säl och skarv påverkar fisken. Rapporten konstaterar att en kvantitativ skattning av olika påverkansfaktorers relativa betydelse för fisken vore önskvärd, inkluderande studier av kumulativa effekter (samverkan och/eller förstärkning) av flera påverkansvariabler som agerar samtidigt. Kumulativa effekter är idag dåligt kända och studerade, men sannolikt betydande för utvecklingen av fiskpopulationerna och fisksamhällena i våra marina vatten. Givet mångfalden av olika påverkansfaktorer, förordas en ekosystembaserad försiktighetsansats vid förvaltning av fiskbestånd, arter och samhällen i våra marina miljöer.

Ecology - Abstract
The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced species are likely to pose an elevated risk of impact to native species and ecosystems. To inform policy, stakeholders and management decisions on global threats to aquatic ecosystems, 195 assessors representing 120 risk assessment areas across all six inhabited continents screened 819 non-native species from 15 groups of aquatic organisms (freshwater, brackish, marine plants and animals) using the Aquatic Species Invasiveness Screening Kit. This multi-lingual decision-support tool for the risk screening of aquatic organisms provides assessors with risk scores for a species under current and future climate change conditions that, following a statistically based calibration, permits the accurate classification of species into high-, medium-and low-risk categories under current and predicted climate conditions. The 1730 screenings undertaken encompassed wide geographical areas (regions, political entities, parts thereof, water bodies, river basins, lake drainage basins, and marine regions), which permitted thresholds to be identified for almost all aquatic organismal groups screened as well as for tropical, temperate and continental climate classes, and for tropical and temperate marine ecoregions. In total, 33 species were identified as posing a & lsquo;very high risk & rsquo; of being or becoming invasive, and the scores of several of these species under current climate increased under future climate conditions, primarily due to their wide thermal tolerances. The risk thresholds determined for taxonomic groups and climate zones provide a basis against which area-specific or climate-based calibrated thresholds may be interpreted. In turn, the risk rankings help decision-makers identify which species require an immediate & lsquo;rapid & rsquo; management action (e.g. eradication, control) to avoid or mitigate adverse impacts, which require a full risk assessment, and which are to be restricted or banned with regard to importation and/or sale as ornamental or aquarium/fishery enhancement.(c) 2021 The Author(s).

- Abstract
Environmental changes due to non-native species introductions and translocations are a global concern. Whilst understanding the causes of bioinvasions is important, there is need for decision-support tools that facilitate effective communication of the potential risks of invasive non-native species to stakeholders. Decision-support tools have been developed mostly in English language only, which increases linguistic uncertainty associated with risk assessments undertaken by assessors not of English mother tongue and who need to communicate outcomes to local stakeholders. To reduce language-based uncertainty, the ‘ecology-of-language’ paradigm was applied when developing the Aquatic Species Invasiveness Screening Kit (AS-ISK), a decision-support tool that offers 32 languages in which to carry out screenings and communicate outcomes to stakeholders. Topics discussed include uncertainty related to language-specific issues encountered during the AS-ISK translation and the potential benefits of a multilingual decision-support tool for reducing linguistic uncertainty and enhancing communication between scientists, environmental managers, policy and decision makers.

Fisken i havet är en resurs som rör sig fritt över nationella gränser. EU har därför en gemensam fiskeripolitik (GFP). Många arter som är viktiga för Sverige regleras inte i GFP och förvaltas därför nationellt. Denna rapport syftar till att: beskriva utvecklingen av fiskeripolitiken förklara den nuvarande politikens mål och regelverk och dess relation till mål och regler på miljöområdet förklara politikens nationella genomförande och det nationella handlingsutrymmet exemplifiera hur Havs- och vattenmyndigheten arbetat med att reglera fisket., Granskare — Slu, Institutionen För Akvatiska Resurser:Alessandro Orio, Andreas Bryhn, Ann-Britt Florin, Charlotte Berkström, Douglas Jones, Erik Degerman, Erik Petersson, Francesca Vitale, Göran Sundblad, Helena Strömberg, Ida Ahlbeck Bergendahl, Jens Olsson, Johan Lövgren, Karl Lundström, Kerstin Holmgren, Konrad Karlsson, Lachlan Fetterplace, Lennart Edsman, Magnus Dahlberg, Magnus Huss, Martin Ogonowski, Mats Ulmestrand, Michele Casini, Rahmat Naddafi, Sara Bergek, Stefan Larsson, Thomas Axenrot, Ulf Bergström, Zeynep Pekcan Hekim, Örjan ÖstmanVetenskaplig Granskare: Eddie Von Wachenfeldt, SluTeknisk Granskare: Per Holliland, Slu Koordinatörer På Slu: Martin Ogonowski, Ann-Britt Florin, Francesca VitaleKontakt Uppdragsgivare: Fredrik Ljunghager, Havs- Och VattenmyndighetenLayout Redaktör: Teresa Soler, Slu

Den 14:e utgåvan av den samlade resursöversikten av fisk- och kräftdjursbeståndens status i våra vatten. I rapporten kan du ta del av bedömningen som görs av situationen för bestånd som regleras inom ramen för EU:s gemensamma fiskeripolitik (GFP). Bedömningarna baseras på det forskningssamarbete och den rådgivning som sker inom det Internationella Havsforskningsrådet (ICES). De bestånd som förvaltas nationellt baseras på de biologiska underlagen, och rådgivningen i huvudsak på den forskning och övervakning samt analys som bedrivs av Institutionen för akvatiska resurser vid Sveriges lantbruksuniversitet (SLU Aqua) samt yrkesfiskets rapportering. Rapporten omfattar 41 fiskarter och åtta skaldjursarter. Nytt för i år är att flodkräftan och signalkräftan har fått egna presentationer. Vi har även ett nytt kapitel "Hållbarhetsbedömning av fisk- och skaldjursbestånd i havsområden runt Sverige”. Det består av en sammanfattning av den årliga bedömningen av hållbarheten i nyttjandet av fisk- och skaldjursbestånd i kust och hav runt Sverige. Bedömningenär baserad på de senaste tre åren vilket möjliggör en jämförelse över tid iantalet hållbart nyttjade bestånd. Jämförelsen visar inga tydliga förändringar över de senaste tre åren. Det finns ett nytt avsnitt i kapitlet ”Från biologi till förvaltning” om hur Havs- och vattenmyndighetens tillståndsgivning går till, och hur bedömningen baseras på resursöversikten vid ansökan om fiskelicens eller annan tillståndsgivning. Kapitlet har också utökats med ett avsnitt där SCB:s fritidsfiskeundersökning beskrivs och hur resultatet används i beståndsanalyserna.

- Abstract
Refined baseline inventories of non-indigenous species (NIS) are set per European Union Member State (MS), in the context of the Marine Strategy Framework Directive (MSFD). 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.

Coastal fish, the fish assemblages in relatively near-shore and shallow (< 20 m depth) coastal areas, in the Baltic Sea harbour a mixture of species with marine and freshwater origins. Typical species are perch, pikeperch, pike, roach and breams, which are of freshwater origin and confined to coastal areas, as well as marine species like flounder, cod and herring, which often have seasonal migrations between nearshore and outer sea areas. Coastal fish populations and communities provide important ecosystem services, contributing to ecosystem functioning and high socio-economic and cultural values. They represent key elements for assessing environmental status in relation to environmental objectives within the Baltic Sea Action Plan (BSAP) and the Marine Strategy Framework Directive (MSFD). The main aim of this report is to provide a comprehensive assessment of the status of coastal fish in the Baltic Sea during 2011-2016, in support of the second holistic assessment of HELCOM (HOLAS II). The results are included in summary in the State of the Baltic Sea report. The report contains the latest status assessment of coastal fish in the Baltic Sea using two Baltic-wide CORE indicators and an agreed assessment approach (Chapter 3). The report also includes a review of major pressures acting on coastal fish communities (Chapter 2), and of potential measures to restore and support coastal fish communities in the Baltic Sea (Chapter 4). The report ends with future recommendations for continued work on coastal fish monitoring and assessment in the Baltic Sea in relation to the BSAP and MSFD (Chapter 5). The status assessments presented in this report includes data from Finland, Estonia, Latvia, Lithuania, Poland, Denmark and Sweden. Experts from Russia and Germany have also participated in the HELCOM work on coastal fish during recent years, but data from these countries are not included in the current assessment. Status is assessed based on the two HECLOM core indicators ‘Abundance of key species’ and ‘Abundance of key functional groups’, of which the latter is composed of a component assessing the abundance of piscivores and one on the abundance of Cyprinids/mesopredators. The results show that the status of the coastal fish communities varies between areas, regions and indicators, but the general status based on the two core indicators appears weak. Only approximately half of the assessed areas and assessment units are classified as being in good status. The more northern areas, where perch is used as the key species, are more often assessed to be in good status than more southern areas, where flounder is recognised as the key species. For the two functional group indicators, the status of piscivores follows a similar pattern of the key species indicator, with relatively better status in more northern areas. The other important functional group, cyprinids, shows insufficient status also in more north-eastern areas of the Baltic Sea as a result of too high abundances. The current monitoring network for coastal fish is rather extensive, but does still only support an assessment in half or less than half of the 42 listed assessment units for coastal fish in the Baltic Sea. The confidence of the assessment is moderate to low, depending on area and indicator, mainly as a result of short time-series, poor spatial representation, and data quality issues. The review of pressures acting on coastal fish communities show that a multitude of natural and human-induced pressures potentially affect coastal fish communities simultaneously. These include for example fishing, habitat exploitation, climate change, eutrophication and natural interactions within the coastal food-web. Whereas a few pressures are strong and often explain a large proportion of the variation in fish abundance and distribution, the effects of others can only be observed locally or under certain conditions and vary across areas and among communities. The potential for generalizations across areas is hence limited, and evaluations of which pressure is of key importance should be undertaken for each individual case separately considering the ambient local conditions in each area together with the range of potential human induced pressures. As a result, measures to restore and protect coastal fish communities should also be developed with a local perspective, and different measures might be relevant in different geographic areas. In general, however, scientific evidence on the effectiveness of different measures is poor, as only few thorough evaluations of implemented measures have been undertaken in the Baltic Sea. The few measures that have been scientifically evaluated with proven effects includes actions aimed at reducing the mortality of fish (e.g. no take areas). There is also partial supportfor temporary fishing closures and gear and catch restrictions. Among measures that aim at improving the production of fish, habitat protection and restoration have proven to be effective. For many other potential measures there is a general lack of scientific support, including biomanipulation, nutrient and substance abatement, as well as stocking of hatchery-reared fish. The assessment results and reviews presented in this report show that coastal fish assessments and monitoring in the Baltic Sea have taken noteworthy steps forward since the last thematic assessment. For example, Baltic-wide CORE indicators on coastal fish have been agreed on, as well as a regionally agreed concept for assessing the status of coastal fish communities. Knowledge has improved on the key pressures impacting on coastal fish communities, and on measures that are potentially most effective for supporting and restoring coastal fish communities. In spite of this, there are still several knowledge gaps and development needs, which should be considered in the future. There is a need to safeguard existing monitoring programs and to initiate new monitoring programs for coastal fish in geographic areas that are currently poorly covered or not possible to assess at all. There is also a need to continue harmonizing assessment approaches to enable comparisons across monitoring programs and data sources, and to further develop common indicators and assessment methods. This concerns the further evaluation and development of current indicators, as well as the development of new generic indicators, focusing on aspects of size-structure in the assessed fish communities. Finally, it is clear that initiatives to strengthen the evaluation measures must be undertaken. It is recommended that the results presented in this report should be used as the basis for following up on the objectives of the BSAP and MSFD, as well as for the development of national management plans and coastal fish assessments in the Baltic Sea.

- Abstract
Under slutet av 2000-talet inkom flertalet rapporter från allmänheten och fiskare i de västra delarna av Hanöbukten om låga förekomster av fisk, förekomst av sårskadad fisk och illaluktande vatten i området. Den här rapporten sammanfattar resultaten och slutsatserna från undersökningar i Västra Hanöbukten utförda under 2015-2017 med syfte att undersöka eventuella samband mellan miljöfarliga ämnen och fiskhälsa, samt orsakerna till uppkomsten av sårskadad fisk i området. Därtill presenteras resultaten från provfisken utförda i syfte att kartlägga bestånden av kustfisk i området. Följande fyra frågeställningar besvaras: Vilka eventuella samband mellan miljöfarliga ämnen och fiskhälsa har framkommit? Vilka orsaker till uppkomst av sårskadad fisk har dokumenterats? Vilka resultat har kartläggningen av kustfiskbestånd, miljöfarliga ämnen respektive fiskhälsa lett till? Vilka slutsatser kan dras gällande vilka arter och storleksklasser som påverkas mest av miljöfarliga ämnen? Resultaten från analyserna av miljöfarliga ämnen i skrubbskädda och torsk visar inte på några generellt förhöjda halter av miljöfarliga ämnen i Västra Hanöbukten under 2015-2016 i jämförelse med referensstationerna Kvädöfjärden och Torhamn (Östra Hanöbukten, skrubbskädda) och sydöstra Gotland (torsk). För några miljögifter såsom DDE och PFOS var halterna hos skrubbskädda något högre i Västra Hanöbukten än i Kvädöfjärden, men halterna ligger under gränsvärden för båda dessa ämnen och inom den naturliga variation som är förväntad med hänsyn till inom- och mellanårsvariation i referensstationer. För torsk visade resultaten att sårskador som antas vara orsakade av nejonöga från Hanöbukten hade högre halter av PCB:er, DDT och dess metaboliter, bromerade flamskyddsmedel och PFAS (poly- och perfluorerade ämnen) jämfört med fiskar utan sårskador i området. Om de högre halterna av miljögifter i sårskadad fisk är ett resultat av lägre kondition och fettvikt hos fisken till följd av sårskadorna

Aims European frogbit (Hydrocharis morsus-ranae L.) is an aquatic plant originating from Europe that has emerged as an invasive species, spreading in the USA and Canada since it was first brought to North America in 1932. It can now be found in many water bodies, from small ponds and long rivers to large lakes such as Lake Ontario and Lake Erie. The continuous spread of this species indicates its success as an invasive species despite legislative attempts to limit its distribution. Catling et al. (Catling PM, Miltrow G, Haber E, et al. (2003) The biology of Canadian weeds. 124. Hydrocharis morsus-ranae L. Can J Plant Sci 83:1001--16) wrote a thorough review about this invasive species in North America. Our review aims for a compilation of the most recent available data and recent studies on H. morsus-ranae L. and focuses primarily on its environmental uses, ecological impacts and management. The purpose of this review is to offer an organized and updated report on European frogbit that can be used towards future studies with the goal of eradicating this invasive species and providing insights on management of other invasive plants. Important Findings Our findings reveal that European forgbit's ecological effects on other species and the invaded environment were shown to be less harmful than previously feared. European frogbit had negative impacts on native plants and reduced dissolved oxygen concentration. However, water chemistry, phytoplankton and zooplankton communities were actually not affected by European frogbit. For fungi, bacteria and macroinvertebrates, studies have showed complex and sometimes conflicting results. We also specifically discussed the new method to control this species using shading and the more recent studies on biological control. Shading with a shade cloth has been shown to effectively remove European frogbit and had minor environmental effects. However, using biological control to combat the spread of the invasive frogbit seems not as successful as we wished. [ABSTRACT FROM AUTHOR]

Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. In a first attempt, I compared the density of Dreissena and the physicochemical data of ecosystems that it invaded among North American and European lakes to identify important factors in its invasion success. Secondly, I investigated the impact of zebra mussels on phytoplankton community composition in a natural lake. Thirdly, I evaluated whether zebra mussel feeding behavior were affected by the presence of predatory waterborne cues. Finally, I examined the effect of Dreissena on seston stoichiometry. A Generalized Additive Model revealed that a joint effect of surface area, mean depth, total phosphorus and calcium concentrations can explain the variability in Dreissena density. Selective grazing by zebra mussels varied in relation to seasonal phytoplankton dynamics. Risk cues released by predators affected both feeding rate and prey selection of the mussels and had cascading indirect effects on phytoplankton biomass and community structure. I found that the flux in nutrients caused by differences in zebra mussel consumption lead to a variation in phytoplankton nutrient limitation. The flexibility of zebra mussel feeding behavior and variation in susceptibility among phytoplankton groups to mussel ingestion indicate that invading zebra mussels could alter phytoplankton community composition of lakes and have important ecosystem consequences. The results of this thesis contribute to the growing evidence that predators indirectly affect resource dynamics and food web structure through their non-lethal effects on consumers. The results suggested that zebra mussel can indirectly both reduce and increase the energy transfer efficiency from primary producers to upper trophic levels in the pelagic and benthic food webs, respectively.
