    The species employed in research and for aquaculture purposes is regarded to pose small risks for transfer of diseases and establishment of feral populations with a substantial biological impact (sub-optimal environmental match and poor competitive abilities with local species). The commercial trade with aquarium species is predominated by tropical species with little environmental overlap. The few temperate aquariums are stocked with local biota. An import ban is proposed for the import of live American lobster (H.americanus) for consumption, and the crab: Percnon gibbesi for aquaria. It is also recommended to ban importation of the green algae Caulerpa taxifolia og C. racemosa, the red algae Rhodymenia pseudopalmata, and the tunicate Botrylloides violaceus. A risk evaluation (for the transfer of non-indigenous species) of the current practice, procedures and standards (National and international) for ecotoxicological studies is also recommended

    OvervĂ„kingsprogrammet for sykdommene bonamiose og marteiliose i flatĂžsters og blĂ„skjell utfĂžres av Havforskningsinstituttet pĂ„ oppdrag fra Mattilsynet. Det ble hentet skjell fra fire ville bestander og ett Ăžstersanlegg, basert pĂ„ utbredelsen av ville skjell og strukturen i ĂžstersnĂŠringen. PrĂžver ble samlet inn i April/Mai og i Oktober, som er de periodene hvor prevalensen av parasittene Bonamia sp. og Marteilia sp. er hĂžyest i smittede bestander. Det ble ikke observert unormal dĂždelighet verken vĂ„r eller hĂžst. Bonamia ostreae / B. exitiosa ble ikke pĂ„vist. Det er kommet inn en rekke rapporter om at blĂ„skjell «forsvinner» mange steder langs kysten. Årsakene til dette er ikke kjent. Parasitten Marteilia sp. ble imidlertid for fĂžrste gang pĂ„vist I blĂ„skjell, Mytilus edulis, pĂ„ BĂžmlo i 2016. Denne pĂ„visningen er fulgt opp med en utvidet prĂžvetaking i HI-prosjekt BlĂ„skjelldĂždelighet (83737-04) i 2017. Det er gjort prĂžvetaking av blĂ„skjell hver tredje mĂ„ned og samlet inn fauna fra funnstedet og blĂ„skjell fra omrĂ„der i nĂŠrheten. Østers fra funnstedet ser ikke ut til Ă„ bli smittet av Marteilia sp. Genetiske studier av Marteilia spp. Fra England, Sverige og Norge (BĂžmlo) er inkludert i en studie som er gjort i EU-prosjektet VIVALDI. Marteilia sp. fra disse omrĂ„dene er ulik Marteilia refringens som forĂ„rsaker sykdom hos flatĂžsters og er foreslĂ„tt gitt navnet Marteilia pararefringens. Det ser sĂ„ledes ut til at Marteilia refringens og Marteilia pararefringens sp. nov. er ulike arter med ulike vertsarter (hhv Ăžsters og blĂ„skjell). Studiene viderefĂžres i 2018, som en kombinasjon av overvĂ„kingsprogrammet og forskningsprosjektet.publishedVersio

    The surveillance and control programme for bonamiosis and marteiliosis in European flat oysters, Ostrea edulis, and blue mussels, Mytilus sp. in Norway in 2016

    Get PDF
    The surveillance programme was carried out in accordance with the model established in 2015, including four wild beds and one oyster farm, based on the present distribution of wild beds, and the structure of the oyster industry. Samples were collected in April/May and in October, in order to be able to detect Bonamia sp. and Marteilia sp. during the periods when the potential prevalence could be at the highest. No abnormal mortalities were observed in oyster populations during the surveillance. Bonamia ostreae / B. exitiosa or microcells resembling Bonamia spp. were not detected during the surveillance programme in 2016. There have been several reports on mortality or “disappearance” of mussels along the Norwegian coast. The reason(s) for the mortalities have not been determined. From one mortality event, at Ytre Hvaler, Østfold, South-eastern Norway, in September 2016, live, presumably moribund mussels were sent to IMR and examined. Affected mussels showed infiltration of bacteria in digestive and connective tissues. Bacteria have been isolated, cultured and frozen for subsequent analysis. No parasites were observed. Marteilia refringens was detected for the first time in mussels, Mytilus sp. collected at Bþmlo, western Norway in October. The prevalence was 50% and most infected mussels exhibited a heavy infection with sporulating Marteilia cells in the digestive epithelia, and affected tissues. A plan for extended survey and a study of the Marteilia refringens in affected mussels has been initiated.publishedVersio

    The surveillance programme is carried out by the Institute of Marine Research according to a contract with the Norwegian Food Safety Authority. Samples were collected from four wild beds, two mussel farms and one oyster farm. Samples were collected in April/May and in October, in order to be able to detect Bonamia sp. and Marteilia sp. during the periods when the potential prevalence could be at the highest. No abnormal mortalities were observed in oyster populations during the surveillance. Bonamia ostreae / B. exitiosa were not detected. The results may be used as a background for an application for disease free status for Norwegian flat oysters. There have been several reports on mortality or “disappearance” of mussels along the Norwegian coast. The reason(s) for the mortalities have not been determined. However, the parasite Marteilia sp. was detected for the first time in mussels, Mytilus edulis at Bþmlo, western Norway, collected during the surveillance programme in 2016. This has been followed up with an extended survey in the IMR research project Mussel mortalities (83737-04). We have performed transmission experiments that identify the time period of infection and the progress of the infection in mussels. Analyses of samples collected in July 2018 indicate that the parasite may be present in an abandoned oyster lagoon at Espevik, Tysnes. The results from the research project indicate that the Marteilia sp detected is limited to mussels. Flat oysters at the same site do not become infected. This is relevant to the listing of susceptible hosts for Marteilia spp. A genetic study of Marteilia spp. from the UK, Sweden and the present site at Aga has been included in a study in the EU-project VIVALDI. The name Marteilia pararefringens has been proposed, and there is strong evidence that Marteilia refringens and Marteilia pararefringens sp. nov. are distinct parasites of bivalves and have different European distributions. After the detection of M. pararefringens in mussels, it is important to obtain more data from mussels along the Norwegian coast. Mussels from Trþndelag in 2018 represented the first samples from mussels north of Bergen. In order to obtain a better set of data, we propose an extended surveillance that could be obtained through a revised surveillance progamme combined with a new model for health control in mollusk farms.publishedVersio

    The surveillance and control programme for bonamiosis and marteiliosis in European flat oysters, Ostrea edulis, and blue mussels, Mytilus sp. in Norway in 2022

    The surveillance programme is carried out by the Institute of Marine Research according to a contract with the Norwegian Food Safety Authority. In 2022, samples were collected from an area in Agder where flat oysters and mussels are harvested from wild beds and farmed, and from one mussel farm in TrĂžndelag county. Samples were collected in April/May and in October, to be able to detect Bonamia sp. and Marteilia sp. during the periods when the potential prevalence in affected populatioons is highest. No abnormal mortalities were observed during the surveillance. Bonamia ostreae / B. exitiosa and Marteilia refringens were not detected. Marteilia pararefringens has been observed in Norwegian mussels since 2016 and a targeted surveillance was carried out in 2022. M. pararefringens has so far been detected at eight sites. All Marteilia isolates have been sequenced and typed as Marteilia pararefringens, which is presumed specific for mussels. The work will be continued in 2023, linked to research on the distribution of M. pararefringens in wild mussels. We propose a revision of the surveillance programme and application for disease free status for Bonamia exitiosa in Norwegian flat oysters. We also propose an application for lifting the suspension of free status for Bonamia ostreae in Arendal and Marteilia refringens at BĂžmlo.The surveillance and control programme for bonamiosis and marteiliosis in European flat oysters, Ostrea edulis, and blue mussels, Mytilus sp. in Norway in 2022publishedVersio

    The impact of offshore wind farms on the marine environment

    Get PDF
    There is an increasing need for energy. Considerable efforts are being made to develop environmentally friendly energy sources. Generating electric energy using wind turbines is one of the methods that has gained widespread, international acceptance. In Norway wind turbine farms are established as well, and more farms are planned for the coming years. Most farms are land based, but from several reasons there are increasing interests in offshore wind farms

    Classification of non-indigenous species based on their impacts: Considerations for application in marine management

    Get PDF
    Assessment of the ecological and economic/societal impacts of the introduction of non-indigenous species (NIS) is one of the primary focus areas of bioinvasion science in terrestrial and aquatic environments, and is considered essential to management. A classification system of NIS, based on the magnitude of their environmental impacts, was recently proposed to assist management. Here, we consider the potential application of this classification scheme to the marine environment, and offer a complementary framework focussing on value sets in order to explicitly address marine management concerns. Since existing data on marine NIS impacts are scarce and successful marine removals are rare, we propose that management of marine NIS adopt a precautionary approach, which not only would emphasise preventing new incursions through pre-border and at-border controls but also should influence the categorisation of impacts. The study of marine invasion impacts requires urgent attention and significant investment, since we lack the luxury of waiting for the knowledge base to be acquired before the window of opportunity closes for feasible management
