Recent advancements in acoustic telemetry (AT) technology have facilitated the collection of long-term data on the movement patterns of marine species, providing a robust framework for evaluating the effectiveness of MPAs in conserving biodiversity, sustaining ecological functions, and supporting resource productivity in surrounding ecosystems. Here, we introduce the RATJADA project, which aims to investigate the role of MPAs in preserving the biodiversity of endangered batoid chondrichthyans (rays) in the Balearic Islands. This initiative will tag and track over 200 individuals from three taxonomic orders—Rajiformes, Myliobatiformes, and Torpediniformes—using long-term acoustic transmitters (&gt;10 years). These tags will be deployed in collaboration with local fishers, with subsequent monitoring carried out by the Balearic Tracking Network over the following decade. The primary objective is to advance our understanding of how MPAs contribute to maintaining the biodiversity and ecological roles of batoid chondrichthyans, a taxonomic group of high conservation concern. Insights gained from this project will inform future conservation strategies and enhance the management of MPAs for long-term ecological sustainability.</p>","License":"https://creativecommons.org/licenses/by/4.0/","StandardTitle":"&nbsp;Effect of Marine Protected Areas on the maintenance of the biodiversity of Balearic Islands batoid chondrichthyans using long-term acoustic telemetry transmitters","doi":null,"vlizDoi":null},{"DasID":5867,"Acronym":null,"EngAbstract":"This is an acoustic telemetry dataset published by the Research Institute for Nature and Forest (INBO).

On Réunion Island, anchored FADs were developed starting in 1988 by IFREMER and contributed to the redeployment of the artisanal fishing fleet toward offshore waters, up to 12 nautical miles from the coast. This development policy led to several positive outcomes: it reduced fishing pressure on vulnerable coastal demersal species, created new fishing grounds further offshore, shortened fishing time, and increased the economic profitability of fishing activities.</p><p>Today, anchored FADs are a vital tool for the maintenance and sustainable development of artisanal fisheries, as the vast majority of small-scale coastal fishing vessels target these FADs as their main fishing areas. Fishing activities around these devices rely on hook-based fishing techniques (trolling lines, handlines, and vertical drifting longlines), which promote a targeted and selective exploitation of mainly adult pelagic species. In order to better understand the interactions between anchored FADs and marine ecosystems, it is necessary to improve knowledge of targeted catches, discards, and to better quantify the fishing effort of professional fleets. The complementarity and experience of the project partners (CRPMEM of Réunion Island, CITEB, IFREMER, and IRD) will make it possible to achieve the expected objectives. The project is designed to meet the fishing sector’s expectations in terms of fishing strategies and sustainable development of pelagic resources around Réunion Island. More broadly, it will improve knowledge of the migratory cycles of pelagic populations at the scale of the Indian Ocean.

Two batches of adult blue crabs were tagged with external ultrasonic transmitters: a first lot (5 males and 5 females) was released in December 2022, and a second lot (10 females) in June 2023. Monitoring lasted 290 days for the first lot and 202 days for the second. Residency and movement index, daily home range (MCPd), and Vemco Positioning System (VPS) data were used to describe crab movements and activity patterns. Residency and movement indexes were larger than 80% for 16 and 8 crabs, respectively. MCPd values ranged between 2516.9 m2 and 21207.2 m2. The movement rate, used as a proxy of activity, was lower for males in spring and summer. Females tended to move towards the open sea in summer, driven by reproductive needs.

In this study, we overall report that among-individuals differences in both spatial behavior and site fidelity of white seabreams in the MPA of Torre Guaceto. Concerning spatial behavior, fish are both located within and out of the MPA over the monitoring period. Within the MPA, the majority of fish over time were, however, detected in a specific area of the Zone A which is composed of matte of <i>Posidonia oceanica</i>, highlighting a clear habitat preference. Also, majority of detection in this area were found during daytime, suggesting feeding activities in this habitat, while fish detections at crepuscule and during nights were lower (and/or detected in rock type habitat) which is probably associated to resting or sheltering phase, using the crevices and holes as a nocturnal refuge. In addition, we found that some individuals showing more fidelity to the site than others during the reproduction while all fish leaving site at the end of July, overall suggesting a seasonal fidelity related to the spawning season. Such results are very promising to better understand spatial behavior and ecology of white seabreams in order to enhance the positive effects of management practices and governance strategies of the MPA, but further studies are needed including higher number of receivers to cover all the MPA and near areas, great number of individuals monitored (including with different size, age, sex) to better understand among-individuals variations, and finally over a longer time period to better highlight the seasonal patterns of individuals</p>","License":"https://creativecommons.org/licenses/by/4.0/","StandardTitle":"Acoustic telemetry data for white seabream (<i>Diplodus sargus</i>) in the Marine Protected Area of Torre Guaceto (Italy)","doi":null,"vlizDoi":null},{"DasID":8643,"Acronym":"Marine_Institute_ClewBay/Achill Receiver Array","EngAbstract":"<p>Acoustic receiver array situated in Clew Bay and Achill, County Mayo, Ireland.

Within a seaward migrating group of trout, large differences in distance migrated away from the river can often be found. Some stay close, while other migrates far away. In this project, we will aim to map physiologically differences between juvenile trout that become residents or migrate to sea and between short and long distance migratory sea trout. Seaward migration is a behavior that can be expected when the gain for the individual fish is higher than the cost. Consequently, one can expect that this behavior will be changed or disappear if sea conditions are so negative for sea trout that it loses reproductive potential by migrating to sea.","License":"https://creativecommons.org/licenses/by-nd/4.0","StandardTitle":"Consequences of land-use change and human activity on anadromous salmonids and the ecosystem services that they provide","doi":null,"vlizDoi":null},{"DasID":8640,"Acronym":"MustelusAsterias_NEA","EngAbstract":"<p>The data is derived from the deployment of mark-recapture and electronic tags on starry smooth-hound (<i>Mustelus asterias</i>) in the North Sea and English Channel.

Sixty hatchery reared salmon smolts were surgically implanted with VEMCO V5 acoustic transmitters to study their downstream migration behavior. Forty of them were released in the river upstream of the lake and the hydropower plant and 20 smolts were released downstream of the hydropower plant in the residual flow of the lake. Only half of the released fishes reached the lake. Thirty five per cent of them entered the hydropower plant and were not observed downstream. The others were predated in the lake. None of the fishes found the entrance to the fish ladder. The results were used to advise local managers.

The European eel entered the fjord during all parts of the tidal cycle and did not seem to utilize the outgoing tidal currents. They migrated mainly during the night, in both the river mouth and the fjord. On average, they spent 2.7 days travelling from the river mouth to the outermost array, 31 km from the river mouth, corresponding to an average migratory speed of 0.5 km/h. The European eel generally migrated in the central part of the fjord and in the uppermost 10–25% of the water column, but with frequent dives to greater depths. Already 4 km after sea entry, European eel were observed diving deeper than 130 m within 20–30 min periods. Hence, this study demonstrated that European eel may perform an active diving behaviour during the early marine migration. The study took place in a pristine area with a minimum of anthropogenic interventions and by individuals from a population still uninfected by the introduced parasite <i>Anguillicoloides crassus</i>.

Eighty smolts were tagged with acoustic transmitters and were tracked for an eight-week period from May to June 2017. High mortality rates were found between the river release location and the three lakes; Loch Garve (25% km-1), Loch Meig (28% km-1) and Loch Achonachie (10% km-1) which was likely the result of predation.

Previous studies on larger hydropower schemes have indicated that the potential environmental impacts of such schemes include: changes in fish population structure; habitat alterations; loss of crucial spawning and nursery habitat; loss of biological diversity; modifications to water quality and hydrological regimes; barriers to fish migration, and disruption of longitudinal connectivity. There are concerns that small hydroelectric schemes may cause similar environmental problems and any impacts may potentially lead to changes in fish population dynamics and thus, deterioration of the river ecological status, which contravenes obligations under the EU Water Framework Directive to achieve good ecological status or potential in all surface water and ground water in all Member States (European Commission Directive 2000). These small hydroelectric schemes may cause direct mortalities to fish (e.g. where fish encounter turbines) and/or indirect mortalities (e.g. where delays to migration make fish more vulnerable to predation). However, there appears to be an acute lack of hard evidence about the impacts of run-of-river schemes on fish passage at single structures, the potential cumulative impacts of a series of structures throughout a river basin, and on the freshwater ecosystem. This limited understanding compromises our ability to develop effective mitigation measures based on sound science, or to conduct the cost-benefit analyses necessary to balance the advantages of renewable energy developments against their potential impacts on fish populations and freshwater communities. In this study, the migration behaviour of European eel (<i>Anguilla anguilla</i>) was studied by means of acoustic telemetry in relation to an in-river hydropower station in the River Frome.

This study aimed to assess the parameters that trigger and guide the migration of silver eels in the largest floodplain lake and associated wetlands in France (the sluice regulated Grand-Lieu Lake). A telemetry survey of 50 acoustic and PIT-tagged female silver eels was performed during the 2015–2016 migration period. We deployed a novel telemetric approach, using receivers to delimit several restricted virtual boxes to determine the instantaneous location of individuals and to transform simple discrete telemetric data into presence/absence data. The low numbers leaving the lake centre are probably explained by the lack of orienting water flows or other environmental clues, but whilst the fate of 34% (17/50) of the tagged eels is unknown, 18% (9/50) were caught by commercial fishermen. Modelling showed that detections were not clearly associated with environmental factors typically involved in riverine migrations (e.g. current velocity, atmospheric pressure and temperature) but they were particularly associated with higher and increasing water levels and, for eels exiting the lake, a sharp increase when sluice gates were opened to an effective gap of &gt;75 cm.

The cause of this decline is unknown, and it is necessary to investigate the migratory behaviour and survival rates of silver eels during the reproductive migration in order to understand if the decline is related to factors acting during that migration. We estimated survival and progression rates of European silver eel migrating in the lower part of the River Gudenaa and during the first phase of the marine migration in the Randers Fjord in Denmark. Fifty migrating silver eel (total body length: 56 to 84 cm) were captured, and each was equipped with an acoustic transmitter. Their migration was subsequently monitored using an array of automatic listening stations, and progression rate and mortality in the river, inner part of the fjord and outer part of the fjord were estimated.</p><p>Survival was high in fresh water. However, 60% of eels were lost in the inner and outer fjord, supporting the hypothesis that mortality is large in the early phase of the marine migration and that fishing may be a major cause of mortality of silver eels. There was no indication that the slowest-migrating individuals were more prone to fishing mortality than the faster-migrating individuals. Progression rate increased as the eels proceeded downriver and out of the fjord. The migration was predominantly nocturnal, both in the river and fjord. Based on the available evidence, a considerable increase in eel survival in the river–fjord system will be needed in order to fulfil the goals in the European Union recovery plan for eels.</p>","License":"https://creativecommons.org/licenses/by/4.0/","StandardTitle":"Silver eel migration in the Gudena River, Denmark","doi":null,"vlizDoi":"10.14284/734"},{"DasID":6332,"Acronym":"2011_Warnow","EngAbstract":"Migration patterns of 146 female silver eels on their way through fresh and brackish water stretches of the Warnow River into the Baltic Sea were studied using acoustic telemetry.

In both areas, the specimens were tagged with acoustic transmitters and floy tag visual tags, biometric and genetic samples were taken, and sex was identified. In the El Toro and Malgrats Islands Marine Reserve, the animals were captured using a containment device during scuba dives and tagged onboard a vessel, while in Migjorn Marine Reserve the capture was done with a hand net during freediving, and the specimens were tagged on land. To date, 16 individuals have been tagged: 3 in El Toro and Malgrats Islands and 13 in Migjorn. Tracking of these specimens is expected to provide information on the species’ distribution in Mallorca, its movement patterns, seasonality, and possible aggregation areas. This project is crucial as it uses advanced technologies to generate valuable data that contributes to the study, stewardship, and conservation of <i>G. altavela, </i>aiding in its long-term preservation in a context of climate change and increasing environmental challenges.</p>","License":"https://creativecommons.org/licenses/by/4.0/","StandardTitle":"Tagging and tracking the butterfly ray (<i>Gymnura altavela</i>) with acoustic telemetry in the Balearic Sea","doi":null,"vlizDoi":null},{"DasID":6435,"Acronym":"Teme barbel 1","EngAbstract":"The study tagged 22 European barbel (Barbus barbus), sampled by a combination of electric fishing (n = 12) and rod and line angling (n = 10), and all were captured within the River Teme.

Being almost in the middle of the Atlantic Ocean and consisting of an archipelago of volcanic islands with small streams running dry during periods of low to no precipitation, it is a unique system across the European-wide habitat range for European eels. In fact, it is the only native teleost inhabiting the freshwater systems on the Azores. As the species is considered a symbol for global change, knowledge on its ecology can be used to assess human impact on aquatic systems. In this project, we track the movement behaviour of yellow eels (i.e. the continental feeding stage) to get a better understanding of their habitat requirements, habitat connectivity in dry-running streams and how they are impacted by anthropogenic activities such as habitat deterioration and pollution. Obviously, the results will contribute to a cost-effective management of the streams on the Azores and the conservation of the critically endangered European eel.</p>","License":"https://creativecommons.org/licenses/by/4.0/","StandardTitle":"Yellow eel movement behaviour in the Azores","doi":null,"vlizDoi":null}],"othrel":null,"othrelrev":null,"ownerships":null,"taxterms":[{"DasTaxtTypID":1,"DasTaxtType":"Taxonomic coverage","TaxtID":15633,"TaxTerm":"Crustacea","AphiaID":1066,"DutchTerm":"Kreeftachtigen"},{"DasTaxtTypID":1,"DasTaxtType":"Taxonomic coverage","TaxtID":19380,"TaxTerm":"Mammalia","AphiaID":1837,"DutchTerm":"Zoogdieren"},{"DasTaxtTypID":1,"DasTaxtType":"Taxonomic coverage","TaxtID":11873,"TaxTerm":"Pisces","AphiaID":11676,"DutchTerm":"Vissen"},{"DasTaxtTypID":1,"DasTaxtType":"Taxonomic coverage","TaxtID":19286,"TaxTerm":"Reptilia","AphiaID":1838,"DutchTerm":"reptielen"}],"frameworks":null,"otherterms":[{"OtherTerm":"Network"},{"OtherTerm":"Oceanographic data management"}],"temporal":[{"DasDateID":4670,"StartYear":2010,"EndYear":null,"StartDay":null,"EndDay":null,"StartDate":"2010-01-01","EndDate":null,"DasDate":null,"Resolution":"Quasi continuous (< 1 min.)","ResolutionNL":"Quasi continu (< 1 min.)","Notes":null,"StartMonth0":null,"StartMonth":null,"StartMonthNL":null,"EndMonth0":null,"EndMonth":null,"EndMonthNL":null,"Progress":"In Progress","ProgressNL":"Gestart"}],"geographical":[{"GeoTerm":"Europe ","DasGeoID":9757,"DasGeoTerm":null,"DasID":5912,"GeotID":7687,"X":null,"Y":null,"MaxX":null,"MaxY":null,"StationName":null,"Precision":null,"CoordSystID":null,"GeoDatumID":null,"OrigCoordMinX":null,"OrigCoordMinY":null,"OrigCoordMaxX":null,"OrigCoordMaxY":null,"OrderNr":null,"Projection":null,"GeoDatum":null,"GeoObjectID":36327,"OrigGeoTerm":"Europe ","DutchTerm":null},{"GeoTerm":"Mediterranean Region","DasGeoID":9758,"DasGeoTerm":null,"DasID":5912,"GeotID":4354,"X":null,"Y":null,"MaxX":null,"MaxY":null,"StationName":null,"Precision":null,"CoordSystID":null,"GeoDatumID":null,"OrigCoordMinX":null,"OrigCoordMinY":null,"OrigCoordMaxX":null,"OrigCoordMaxY":null,"OrderNr":null,"Projection":null,"GeoDatum":null,"GeoObjectID":4278,"OrigGeoTerm":"Mediterranean Region","DutchTerm":null},{"GeoTerm":"North Atlantic Ocean","DasGeoID":9759,"DasGeoTerm":null,"DasID":5912,"GeotID":12,"X":null,"Y":null,"MaxX":null,"MaxY":null,"StationName":null,"Precision":null,"CoordSystID":null,"GeoDatumID":null,"OrigCoordMinX":null,"OrigCoordMinY":null,"OrigCoordMaxX":null,"OrigCoordMaxY":null,"OrderNr":null,"Projection":null,"GeoDatum":null,"GeoObjectID":1912,"OrigGeoTerm":"North Atlantic Ocean","DutchTerm":"Noord Atlantisch"}],"meastypes":null,"dasthemes":[{"DasThemeID":28,"DasTheme":"Biology > Fish","DasTheme0":"Fish","DutchTerm":"Vis"},{"DasThemeID":37,"DasTheme":"Fisheries > Fish stocks/catches/taggings","DasTheme0":"Fish stocks/catches/taggings","DutchTerm":"Visstocks/vangsten/merken"}],"projects":null,"refs":null,"urls":[{"URL":"https://rshiny.lifewatch.be/etn-data/","externalID":null,"URLTypeCode":null,"URLType":"Online dataset","URLTypID":19,"downloadURL":null,"FileName":null}],"pictures":null,"urlmaps":null,"spatreps":null,"fileformats":null,"resmessage":"","complete":1}
