    • CV21_01 INFOMAR Survey Report

      Sheehan, Kevin; INFOMAR Survey Team (Marine Institute, 2022)
      Geological Survey Ireland (GSI) and Marine Institute (MI) conducted seabed mapping between 2003 and 2005 under the auspices of the Irish National Seabed Survey (INSS) and this continued from 2006 to present day under the INtegrated mapping FOr the sustainable development of Irelands MArine Resource (INFOMAR) programme. INSS was one of the largest marine mapping programmes ever undertaken globally, with a focus on deep water mapping. INFOMAR is a joint venture between the GSI and the MI and is funded by the Irish Government through the Department of the Environment, Climate and Communications (DECC). INFOMAR Phase 1, 2006 to 2015 focused on mapping 26 priority bays and 3 priority areas around Ireland and creating a range of integrated mapping products of the physical, chemical and biological features of the seabed in those areas. INFOMAR Phase 2, 2016 to 2026 intends to map the remainder of Ireland’s entire seabed. As of 2018 the remaining survey area has been split at the 30 nautical mile limit (Nm). The inshore survey fleet, managed by GSI is responsible for mapping inshore of the 30Nm limit and the MI vessels are responsible for mapping the offshore.

    • Aran, Galway Bay and Slyne Head Nephrops Grounds (FU17) 2022 UWTV Survey Report and catch scenarios for 2023

      Aristegui, M.; Doyle, Jennifer; Bentley, K.; Graham, Jessica; O’Brien, Elizabeth; Oliver, Patrick; Ryan, Gráinne (Marine Institute, 2022)
      This report provides the main results and findings of the 21st annual underwater television survey on the Aran, Galway Bay and Slyne head Nephrops grounds, ICES assessment area; Functional Unit 17. In 2022, due to disruption to the survey schedule caused by weather downtime, the UWTV survey could not complete the Aran Grounds and Slyne Head stations, and was only able to complete successfully the 5 Galway Bay stations. The survey was multi-disciplinary in nature collecting UWTV, CTD and other ecosystem data. The mean burrow density observed in Galway Bay, adjusted for edge effect, was 0.19 burrows/m2; and the final abundance estimate for this ground was 15 million burrows with a CV (Coefficient of Variance; relative standard error) of 3%. There were no sea-pen species nor trawl marks observed in the footage from Galway Bay. The 2022 UWTV survey was not deemed robust enough to derive fishing advice for 2023 owing to the reduced number of stations. As such, the stock size is considered unknown for 2022. Therefore, the assessment and catch advice for 2023 is based on the 2021 UWTV survey. The 2021 combined abundance estimate (331 million burrows) was below the MSY Btrigger reference (540 million burrows). Using the 2021 estimate of abundance and updated stock data imply that catches in 2023 should be no more than 363 tonnes, according to the EU MAP and ICES MSY approach and assuming that discard rates and fishery selection patterns do not change from the average of 2019–2021.
    • Summary Report on 2021 Residue Monitoring of Irish Farmed Fish & 2021 Border Inspection Post Fishery Product Testing undertaken at the Marine Institute

      Glynn, Denise; McGovern, Evin; Farragher, E.; Kelly, Corrine; Moffat, R.; Kaur, Navdeep; Toomey, M. (Marine Institute, 2022)
      On behalf of the Department of Agriculture, Food and Marine (DAFM), the Marine Institute carries out monitoring of chemical residues in finfish for aquaculture sector. This monitoring is set out in the annual National Residue Control Plan, which is approved by the European Commission, and is an important component of the DAFM food safety controls and is implemented under a service contract with the Food Safety Authority of Ireland. Since 1999, the Marine Institute has implemented the National Residues Monitoring Programme for aquaculture. This is carried out on behalf of the Sea Fisheries Protection Authority, which is the responsible organisation for residue controls on farmed finfish. In 2021, in excess of 632 tests and a total of 1,870 measurements were carried out on 120 samples of farmed finfish for a range of residues. Implementation of the Aquaculture 2021 Plan involves taking samples at both farm and processing plant: *80 target samples taken at harvest: 70 farmed salmon and 10 freshwater trout. *40 target samples were taken at other stages of production: 30 salmon smolts and 10 freshwater trout. All 2021 samples were compliant. For target sampling of farmed fish, a summary table of the residue results from 2005 - 2021 is outlined in Table 1. Overall, the outcome for aquaculture remains one of consistently low occurrence of residues in farmed finfish, with no non-compliant target residues results for the period 2006-2014, 0.11% and 0.10% non-compliant target residues results in 2015 and 2016 respectively and no non-compliant target results for the period 2017 to 2021.
    • Underwater Television Survey Marine Mammal Observer Report RV Tom Crean 13 – 23 August 2022

      Perez Tadeo, M. (Marine Institute, 2022)
      The Underwater Television Survey (UWTV) on the Porcupine Bank took place from the 13th to the 23rd of August, 2022 on board the Marine Institute’s R.V. Tom Crean. The research survey covered an area on the Porcupine Bank Nephrops grounds. A marine mammal dedicated survey was carried out by an observer on board following a standard single platform line-transect methodology aiming to collect relative abundance and distribution of marine mammals in the area of interest. The marine mammal survey was conducted during 8 days. The total amount of time the marine mammal observer spent on effort was 64 hours, 1 minute and 1 second. Environmental conditions varied between survey days. Visibility was overall good, with most time spent on effort under visibility 5 (i.e. from 16 to 20 km) accounting for 32.13% and visibility 6 (i.e. >20 km), accounting for 28.44% of the time. On the other hand, sea state conditions were not favourable, since most of the effort was carried out under sea state 5 (45.62% of the time). Swell height was recorded as higher than 2 m during most of the time spent on effort (62.75% of the total time). Marine mammal survey effort was carried out during all days while traveling, with the exception of the 19/08/2022, when effort had to be interrupted due to adverse weather conditions. A total of 10 sightings of marine mammal species were recorded over the course of the survey, with common dolphins accounting for 60% of these sightings.

    • Monitoring the recovery of exploited deep-water species

      Kelly, Eoghan; Gerritsen, Hans D (Marine Institute, 2022)
      Commercial fisheries for deep-water species off the Irish coast developed in the late 1990s and declined in the early 2000s. Many of the exploited stocks were depleted a result of commercial exploitation and ICES has advised a zero catch for Orange Roughy since 2004, and for Portuguese Dogfish and Leafscale Gulper shark since 2005. Since 2016, the deep water access regulation has effectively banned trawling in waters deeper than 800 m (EC, 2016) and fishing for deep-water sharks with static netting >600 m is also banned by the technical measures regulation (EC, 2019). However, some of these species continue to be caught, either by gears not covered by this regulation or in water <800 m deep. The Marine Institute carried out a survey programme to assess the distribution and abundance of these species between 1992 and 1999 and again between 2006 and 2009. Since 2019, 3 days of the Irish Anglerfish and Megrim Survey have been allocated to monitoring the recovery of commercial deep-water species. This work was funded under the European Maritime and Fisheries Fund (EMFF) from 2019 to 2021 and European Maritime, Fisheries and Aquaculture Fund (EMFAF) since 2022. The main objective of the current project is to assess the recovery of exploited deep-water species in Irish waters by comparing the results from 2019 to 2022 surveys with those from the previous period in 2006 to 2009 (methods used in the earlier period 1992 to 1999 were different, therefore a direct comparison with that period is not possible).
    • Supply of Vertebrate Necropsy and Sample Recovery Services Merged Final Reports

      Levesque, Stephanie; O'Donovan, Jim; Daly, Mags; Murphy, Sinéad; O'Connell, Mick; Jepson, Paul; Deaville, Rob; Barnett, James; Berrow, S.D. (Marine Institute, 2021)
      The Marine Institute issued a tender for the Supply of Vertebrate Necropsy and Sample Recovery Services Tender (2017-2018). The results are presented in this report. These tenders required i) the recovery and standardised necropsy of three cetacean species with associated case history reporting, ii) the provision of sampling kits to be used for the recovery of tissue samples collected from bycaught animals (birds, seals and cetaceans) by observers on commercial inshore and offshore fishing vessels in Irish waters in order to provide additional data to the MI’s existing catch sampling programme and iii) the storage and subsequent delivery of all samples and associated databases to the client. Recovery of 24 animals from two geographical lots was the target for the initial contract (2017) and was achieved. The contract extension (early 2018) required the collection and necropsy of a further 16 animals, which was exceeded as 19 animals were collected. A target of 30 animals to be recovered was required in the second contract (2018) and was also successfully reached. These 73 animals comprised 53 common dolphins (Delphinus delphis), ten striped dolphins (Stenella coeruleoalba) and ten harbour porpoises (Phocoena phocoena). Forty-one of the 73 (56%) individuals were recovered from Lot 1 from counties Clare to Donegal, while 32 (44%) individuals were recovered from Lot 2 from counties Wexford to Kerry. Thirty-five sampling kits were assembled and delivered to the Marine Institute, and additional kits were prepared and available upon request for distribution to their panel of fishery observers. Between 24 July and 14 December 2017, two adult male grey seals were incidentally captured in tangle nets and reported to the Project Coordinator. Results from these tenders will inform the development of a long-term strategy for necropsy of stranded cetaceans and recovery of tissue samples for further biological studies. Samples requiring long-term storage at -20°C, including those for virology, were transported in a portable refrigerator to the IWDG office in Kilrush, Co. Clare and stored at facilities on site. Formalin fixed tissues, such as reproductive organs and adrenal glands, were stored at the RVL in Cork. All samples have been delivered to the Marine Institute in Oranmore, Co. Galway along with a detailed database of samples collected.
    • Nephrops and Microplastics

      Joyce, Haleigh; Frias, João; Kavanagh, Fiona; White, Jonathan; Nash, Róisín (Marine Institute, 2022)
      Plastic litter, once introduced into the marine environment can fragment into smaller plastic pieces known as microplastics (MPs) due to weathering and degradation. The ubiquitous nature of MPs has led to an increased focus on commercial seafood species as there is potential for this contaminant to enter the human food chain. Several studies to date have reported MPs in the GIT of the Dublin Bay Prawn, Nephrops norvegicus and the surrounding sedimentary environment. The Dublin Bay prawn, N. norvegicus is one of the most commercially important species landed by the Irish Fleet, worth approximately €37 million in 2020. Due to their high economic value, spatial distribution, and ecological relevance N. norvegicus have the potential to be used as a bioindicator for MP contamination and can be used to provide information to guide policy makers and environmental managers. This research focuses on the MP loadings in N. norvegicus and the exploration of a potential relationship with their surrounding sedimentary habitat within six primary N. norvegicus fishing grounds in the North East Atlantic. While N. norvegicus has been documented to ingest MPs, this research builds on the knowledge base through exploring the ingestion and retention times of MPs of varying sizes. This research proposes a pan-European monitoring programme to detect MP abundances and changes in levels through the use of N. norvegicus as a potential bioindicator for MP contamination.

    • Cruise report: Irish Anglerfish & Megrim Survey 2022

      Kelly, Eoghan; Gerritsen, Hans D; Aristegui Ezquibela; Moore, Claire; Moore, S.J.; Stokes, David (Marine Institute, 2022)
      The 2022 Irish Anglerfish and Megrim Survey (IAMS) took place from 5th February to 1st March (area 7bcjk) and 12-22nd April 2022 (area 6a) on RV Celtic Explorer. The main objective of the survey is to obtain biomass and abundance indices for anglerfish (Lophius piscatorius and L. budegassa) and megrim (Lepidorhombus whiffiagonis and L. boscii) in areas 6a (south of 58°N) and 7 (west of 8°W). Secondary objectives are to collect data on the distribution, relative abundance and biology of other commercially exploited species. For the fourth year, additional sampling took place in deep water (up to 1,500m) in order to monitor the recovery of exploited deep-water species following the decline of the deep-water fisheries in Irish waters. The IAMS survey is coordinated with the Scottish Anglerfish and Megrim Survey (SIAMISS) and uses the same gear and fishing practices.
