The National Monitoring Programme for Residues in Farmed FishThe National Monitoring Programme for Residues in Farmed Fish is a key component of Ireland’s compliance with European Union legislation on food safety and veterinary medicine use in aquaculture. The Marine Institute (MI) implements this programme through sampling and testing for monitoring of chemical residues for farmed fish. on behalf of the the Department of Agriculture, Food and the Marine (DAFM), in collaboration with the Food Safety Authority of Ireland (FSAI) and the Sea Fisheries Protection Authority (SFPA). The programme forms part of the National Residue Risk-Based Control Plan (NRBCP). This plan ensures that farmed finfish are monitored for residues of veterinary medicines and other chemical substances, safeguarding consumer health and supporting sustainable aquaculture practices. The programme aligns with EU regulations, including Regulation (EU) 2017/625 and its associated delegated and implementing acts, and is submitted annually to the European Commission for review and approval. Through targeted sampling and analysis, the programme aims to detect the misuse of authorised treatments and the presence of unauthorised substances, thereby upholding food safety standards and public confidence in aquaculture products.

High-density SNP panel provides little evidence for population structure in European sea bass (<i>Dicentrarchus labrax</i>) in waters surrounding the UKThe European sea bass (Dicentrarchus labrax) is a commercially and recreationally important fish widely, distributed across the Northeast Atlantic Ocean and Mediterranean Sea. Two distinct lineages that represent the Atlantic and Mediterranean regions have been previously identified, with a hybrid zone close to the Almeria–Oran front. The presence of fine-scale population structure within the Northeast Atlantic region is less clear. Here, we investigated population structure in adult samples obtained from the northern part of the Atlantic range surrounding the UK, Ireland, Belgium, Germany, France, the Netherlands, and Norway, along with outgroups from Portugal and the Mediterranean, using a panel of 41 K single nucleotide polymorphism markers. Population structure among Northeast Atlantic Ocean samples was weak in both spawning—(FST = 0.00022) and feeding—(FST = 0.00032) season data sets, with small pairwise FST values between sample pairs. However, average FST was larger between spawning samples than between feeding samples, with a pattern of isolation-by-distance among the spawning samples, but not the feeding samples, suggesting some biologically meaningful population structure. The largest pairwise FST values at both International Council for the Exploration of the Sea (ICES) rectangle and division scales involved a sample from the west of Ireland. We found no evidence of a gradient in “Mediterranean” ancestry among samples collected around the UK in our data set or in a reanalysis of a published data set where such a pattern had been previously identified. In summary, there was no evidence that sea bass in different ICES divisions within the Northeast Atlantic Ocean represents genetically separate populations. Further work is required to reconcile evidence from tagging and modelling studies that suggest the potential for demographic independence with the genetic data.

International Blue Whiting Spawning Stock Survey (IBWSS) Spring 2025Coordination of the survey was initiated at the meeting of the Working Group on International Pelagic Surveys (WGIPS) in January 2025 and continued by correspondence until the start of the survey. During the survey, effort was refined and adjusted by the survey coordinator (Norway) using real time observations.
