Aquaculture is currently the fastest expanding global animal food production sector and is a key future contributor to food security. An increase in food security will be dependent upon the development and improvement of sustainable practices. A prioritization exercise was undertaken, focusing on the future knowledge needs to underpin UK sustainable aquaculture (both domestic and imported products) using a 'task force' group of 36 'practitioners' and 12 'research scientists' who have an active interest in sustainable aquaculture. A long list of 264 knowledge needs related to sustainable aquaculture was developed in conjunction with the task force. The long list was further refined through a three stage process of voting and scoring, including discussions of each knowledge need. The top 25 knowledge needs are presented, as scored separately by 'practitioners' or 'research scientists'. There was similar agreement in priorities identified by these two groups. The priority knowledge needs will provide guidance to structure ongoing work to make science accessible to practitioners and help to prioritize future science policy needs and funding. The process of knowledge exchange, and the mechanisms by which this can be achieved, effectively emerged as the top priority for sustainable aquaculture. Viable alternatives to wild fish-based aquaculture feeds, resource constraints that will potentially limit expansion of aquaculture, sustainable offshore aquaculture and the treatment of sea lice also emerged as strong priorities. Although the exercise was focused on UK needs for sustainable aquaculture, many of the emergent issues are considered to have global application. © 2015 John Wiley & Sons Ltd.

Pursuit of the triple bottom line of economic, community and ecological sustainability has increased the complexity of fishery management; fisheries assessments require new types of data and analysis to guide science-based policy in addition to traditional biological information and modeling.We introduce the Fishery Performance Indicators (FPIs), a broadly applicable and flexible tool for assessing performance in individual fisheries, and for establishing cross-sectional links between enabling conditions, management strategies and triple bottom line outcomes. Conceptually separating measures of performance, the FPIs use 68 individual outcome metrics-coded on a 1 to 5 scale based on expert assessment to facilitate application to data poor fisheries and sectors-that can be partitioned into sectorbased or triple-bottom-line sustainability-based interpretative indicators. Variation among outcomes is explained with 54 similarly structured metrics of inputs, management approaches and enabling conditions. Using 61 initial fishery case studies drawn from industrial and developing countries around the world, we demonstrate the inferential importance of tracking economic and community outcomes, in addition to resource status. © 2015, Public Library of Science.

New England coastal and adjacent Nova Scotia shelf waters have a reduced buffering capacity because of significant freshwater input, making the region’s waters potentially more vulnerable to coastal acidification. Nutrient loading and heavy precipitation events further acidify the region’s poorly buffered coastal waters. Despite the apparent vulnerability of these waters, and fisheries’ and mariculture’s significant dependence on calcifying species, the community lacks the ability to confidently predict how the region’s ecosystems will respond to continued ocean and coastal acidification. Here, we discuss ocean and coastal acidification processes specific to New England coastal and Nova Scotia shelf waters and review current understanding of the biological consequences most relevant to the region. We also identify key research and monitoring needs to be addressed and highlight existing capacities that should be leveraged to advance a regional understanding of ocean and coastal acidification. © 2015 The Oceanography Society.

We report on a rapid and practical method to assess social dimensions of performance in small-scale and industrial fisheries globally (SocialWellbeing in Fisheries Tool (SWIFT)). SWIFT incorporates aspects of security (fairness and stability of earnings, benefits of employment to local fishing communities, worker protection, and personal safety and health in communities associated with fisheries); flexibility (including opportunity for economic advancement); and the fishery's social viability (including whether the fishery is recruiting new harvesters and diverse age classes of workers, whether women's participation and leadership in global production networks are on an upward trajectory.). We build on resilience research by conceptualizing wellbeing in terms of security, flexibility, and viability, and assessing wellbeing at individual, community, and system levels. SWIFT makes social performance measures more broadly accessible to global production networks, incorporates an everyday understanding of wellbeing for people involved in the seafood industry, and helps put social sustainability into measurable terms that are relevant for businesses. © 2016 by the authors.

Genetic stock structure is atypical in tuna species, with most species demonstrating geographically-broad, panmictic populations. Here, genetic data suggest a distinct pattern for Thunnus tonggol across the Indo-Pacific region. The genetic variation in the coastal tuna T. tonggol sampled from across the South China Sea was examined using the highly variable mitochondrial DNA displacement loop (D-loop) gene region. One hundred and thirty-nine specimens were sampled from four locations in Indonesia, Vietnam and the Philippines. Phylogenetic reconstruction of genetic relationships revealed no significant ΦST statistics and hence no population structure within the South China Sea. However, subsequent analysis with sequence data from coastal northwest India infers discrete genetic stocks between the Indian Ocean and the South China Sea. Consistent with previous genetic analyses of tuna species in the Indo-Pacific, the findings in this study infer no population structure within each basin, but rather show a significant partitioning across the wider region. Furthermore, these results have implications for the management of the commercially valuable Thunnus tonggol across national boundaries, and thus requiring collaboration among countries to ensure its sustainable use. © 2016 Blackwell Verlag GmbH.

This paper reports recent developments in Rapfish, a normative, scalable and flexible rapid appraisal technique that integrates both ecological and human dimensions to evaluate the status of fisheries in reference to a norm or goal. Appraisal status targets may be sustainability, compliance with a standard (such as the UN code of conduct for responsible fisheries) or the degree of progress in meeting some other goal or target. The method combines semi-quantitative (e.g. ecological) and qualitative (e.g. social) data via multiple evaluation fields, each of which is assessed through scores assigned to six to 12 attributes or indicators: the scoring method allows user flexibility to adopt a wide range of utility relationships. For assessing sustainability, six evaluation fields have been developed: ecological, technological, economic, social, ethical and institutional. Each field can be assessed directly with a set of scored attributes, or several of the fields can be dealt with in greater detail using nested subfields that themselves comprise multidimensional Rapfish assessments (e.g. the hierarchical institutional field encompasses both governance and management, including a detailed analysis of legality). The user has the choice of including all or only some of the available sustainability fields. For the attributes themselves, there will rarely be quantitative data, but scoring allows these items to be estimated. Indeed, within a normative framework, one important advantage with Rapfish is transparency of the rigour, quality and replicability of the scores. The Rapfish technique employs a constrained multidimensional ordination that is scaled to situate data points within evaluation space. Within each evaluation field, results may be presented as a two-dimensional plot or in a one-dimensional rank order. Uncertainty is expressed through the probability distribution of Monte-Carlo simulations that use the c.l. on each original observation. Overall results of the multidisciplinary analysis may be shown using kite diagrams that compare different locations, time periods (including future projections) and management scenarios, which make policy trade-offs explicit. These enhancements are now available in the R programming language and on an open website, where users can run Rapfish analyses by downloading the software or uploading their data to a user interface. © 2013 The Fisheries Society of the British Isles.

Indonesia, the Philippines, and Papua New Guinea, all part of a regional sub-group known as the Coral Triangle, have sizeable skipjack, yellowfin and bigeye tuna fisheries. Recent figures suggest that as much as a third of tuna catch from the western and central Pacific Ocean can be attributed to the fleets of these countries. Historically, however, little attention has been paid to their fisheries and their regulations. Management of tuna fisheries in Indonesia and the Philippines faces many challenges, including bycatch of juveniles, lack of effective gear restrictions, subsidized fleets, and unreported catches. Papua New Guinea has countered the challenges of tuna management with several effective measures, including implementing the vessel day scheme, a type of effort quota system, and limiting the use of fish aggregating devices (FADs). This paper compares and contrasts tuna fisheries in the three countries, as well as their management regimes and current management challenges. By highlighting some of the successes that Papua New Guinea has had, we hope that Indonesia and the Philippines may be able to more effectively manage their fleets and their fish. And this in turn may lead to better regional management of a valuable transboundary resource. © 2012 Elsevier Ltd.

"Limit reference points" define a state at which fishery management has reached overfishing, overfished stock status, or some other regulatory or conservation point of concern. In many Pacific salmon Oncorhynchus spp. fishery jurisdictions, management only uses "target reference points"-the specific numerical management objective intended to bring about some fishery benefit. There are several reasons to adopt limit reference points, and jurisdictions without previously defined limit reference points could adopt them in order to align better with the Magnuson-Stevens Act (American fisheries) or, more importantly, to facilitate cross-jurisdiction sustainability assessments, which are increasingly needed for certifications of sustainability. In actual practice, the stock size of 0.5 times a target reference point has been used as a limit reference point for some Pacific salmon fisheries, or at least as a proxy for a limit reference point. We term this point the "minimum stock size threshold," following a convention already in use, and we note that limit reference points defined this way are increasingly being accepted as a standard either because of justification based on simulation and fishery principles or for purely pragmatic reasons.Received July 2, 2013; accepted January 6, 2014. © 2014 © American Fisheries Society 2014.
