    The objective of the Twelfth Workshop on the Development of Quantitative Assessment Methodologies based on Life-history traits, exploitation characteristics, and other relevant parameters for data-limited stocks (WKLIFE XII) was to further develop methods for stock assessment, stock status, and catch advice for stocks in ICES Categories 2–6, focusing on the provision of sound advice rules adhering to the ICES advisory framework and principles for fisheries management. This report addresses (i) questions from different ICES assessment working groups and stakeholders regarding the applicability of the data-limited technical guidelines, (ii) the prioritisation of future tasks regarding the ICES data-limited framework, (iii) further development and testing of data-limited methodologies with specific focus on the review of the current ICES advice framework for stock Categories 4-6, spatial indicators, and reference points for surplus production models, and (iv) other relevant data-limited topics. A survey of participants resulted in a high prioritisation score of four topics of the ICES data-limited roadmap: (1) risk equivalence, best available science, guidelines and communication of data-limited methods, (2) value of information of different data-types and data preparation, (3) better advice for slow-growing species, and (4) observation and parameter uncertainty in empirical harvest control rules and length-based approaches. The current ICES approach for Category 5 and 6 stocks, with an advice for constant annual catch and a periodic reduction with a precautionary buffer, is a form of non-adaptive management and an initial review revealed that it may not be precautionary if a stock is overfished but also overly precautionary in other situations. An exploration of spatial indicators showed that these have the potential to inform on stock status. A stochastic definition of MSY Btrigger for surplus production models takes uncertainty into account and leads to higher reference values than the current definition for stocks with low and intermediate biomass variability.
  • Next Generation EV Batteries Eliminate the Need for Deep Sea Mining.

    Everett, Jeanne; Kammen, Daniel; Rowland, Stan; Blue Climate Initiative (Blue Climate Initiative, 2023-10)
    Advances in electric vehicle (EV) battery technology, and the accelerating adoption of these technologies, are leading to the replacement of EV batteries dependent on cobalt, nickel, and manganese. As a result, the deep sea mining of these metals is neither necessary, economically advantageous, or environmentally advisable. In fact, efforts to promote the mining of these metals in the deep ocean now serve neither manufacturers nor consumers, but only enterprises that have been established for the express purpose of deep sea mining. Typically, companies and consumers are asked to make sacrifices for the good of conservation and the environment. Now, happily, what is good for both enterprise and the end consumer, also serves the need to protect and preserve our oceans, and the life that resides within.
  • Workshop to Scope Assessment Methods to Set Thresholds (WKBENTH2)

    Artigas, Miquel Canals; Baldrighi, Elisa; Belin, Alice; Bell, James; Bendraoui, Abdeladim; Beukhof, Esther; Blomqvist, Mats; Boyé, Aurélien; Di Lorenzo, Bianca; Di Bona, Gabriele; et al. (International Council for the Exploration of the Sea, 2022)
    The Marine Strategy Framework Directive (MSFD) requires Member States to achieve good environmental status (GES) across their marine waters. The EU have requested ICES to advise on methods for assessing adverse effects on seabed habitats, through selection of relevant indicators for the assessment of benthic habitats and seafloor integrity and associated threshold values for GES in relation to Descriptor 6 – Seabed integrity under the MFSD. Two sets of criteria were developed to evaluate indicators and thresholds respectively for evaluation of suitability for assessing GES. 16 indicator and 12 threshold criteria were compiled and weighted by importance. The criteria were designed for evaluation at a subregional or regional level. The scoring for these criteria is meant as a guidance when choosing indicators and thresholds, so failure to meet one criterion will not necessarily prevent the use of the indicator or thresh-old in an assessment. The framework was evaluated for 6 indicators and for 11 methods for setting thresholds. The criteria were found to be useful for evaluation both indicators and thresholds. The process works most consistently when there are experts in the group on both the criteria themselves and on the indicators and thresholds. The MFSD Descriptor 6 determination of GES needs both a quality threshold (when are seabed habitats in a good state in a specific location) and an extent threshold (proportion of the assessment area that needs to have seabed habitats in good state). Eleven different methods for setting thresholds were identified, of which more are suitable for setting quality than for extent thresholds. Preferred methods identified an ecologically-motivated difference between a good and de-graded state, rather than another transition. Quality thresholds based on the lower boundary of the range of natural variation were considered most promising. This approach can be used for most, but not all, indicators. The WK collated a standardized dataset to test the specificity, sensitivity and/or responsiveness of sampling-based benthic indicators to pressure gradients for evaluation by WKBENTH3. Risk-based methods will be evaluated as maps and by scored sensitivity and impact score per MSFD habitat type and subdivision. Participants provided input into the selection of indicators for the compilation of indicators. A template was developed for documenting the characteristics of each indicator to facilitate the evaluation of the indicators.
  • Workshop on ICES Reference Points (WKREF2)

    Orio, Alessandro; Kemp, Alexander; Pierucci, Andrea; Kuparinen, Anna; Rindorf, Anna; Peyronnet, Arnaud; Wilson, Ashley; Albertsen, Christoffer Moesgaard; Konrad, Christoph; Sparrevohn, laus Reedtz; et al. (International Council for the Exploration of the Sea, 2022-01-05)
    The ICES Workshop on ICES reference points (WKREF2) was tasked review the WKREF1 report and based on the outcome develop updated guidelines for the ICES reference points system and recommendations for ACOM consideration. The WKREF1 report has suggested 5 key recom- mendations to simplify and harmonise the ICES reference points framework representing a ma- jor change to the current guidelines. At WKREF2, we detailed discussions and four key concerns were raised about the proposed approach. The first related to the simplification of rules to define Blim. Around two thirds of category 1 stocks would end up as WKREF1 “Blim Type 2” where Blim would be set as a fraction of B0. The Allee effect or “depensation” maybe more important than previously thought and should be furthered explored for ICES stocks since it has important consequences for Blim. A number of challenges and issues around defining Blim using the current guidelines were documented. Some suggestions on improvement criteria were discussed including using classifiers to define spas- modic stocks and using change point algorithms to address non-stationary productivity regimes. However, further work is need to make these approaches operational and there was no consen- sus that the WKREF1 Blim types should replace the current guidelines. WKREF1 recommended that the FMSY proxy should be based on a biological proxies and should be less than the deterministic FMSY. It was pointed out that the stochastic FMSY estimated in EqSim for example, is lower than the deterministic FMSY and that the current guidelines ensure that the FMSY should not pose a more than 5% risk to Blim. A large amount of work described in WD 1 was carried out to develop an MSE framework to consistency and robustness test a candidate refer- ence point system for North East Atlantic stocks. However, WKREF2 recommended that further work needs to be carried out to condition and test the simulation framework before the conclu- sions could be adopted by ICES and incorporated into the guidelines. A number of considerations for defining MSY related reference points were discussed including using model validation and prediction skill to ensure that ICES provide robust and credible ad- vice. There is evidence that density dependence (DD) is important in the majority of ICES stocks (68% in recruitment and 54% in growth). The correct prediction of the shape and strength of density-dependence in productivity is key to predicting future stock development and providing the best possible long-term fisheries management advice. A suggested approach to use surplus production models (SPMs) to account for DD in FMSY was suggested and discussed but there was no consensus on whether that approach was appropriate. There was consensus that the FECO approach as a means of adapting target fishing mortality to medium-term changes in productiv- ity should be included in the guidelines subject to a benchmark and ACOM approval. While WKREF1 and 2 focused mainly on Category 1 stocks ToR c) called for a “simplified and harmonised set of guidelines for estimating MSY and precautionary reference points applicable in the advice framework across various ICES stock categories.” Ideally the ICES assessment cat- egories should provide equivalent risk across all stocks. This issue was discussed but no recom- mendations emerged. There was no consensus a revised reference point framework was proposed at WKREF2. How- ever, it was agreed that it should be presented here for further discussion at ACOM and other fora. The key feature of the suggested approach is that the stock status evaluation is treated in- dependent of the Advice Rule (AR). The main feature of the system is that the biomass trigger is not linked to a stock status evaluation, it is linked to the expected biomass when fishing at the target fishing mortality, in contrast to the current ICES approach. It also entailed that FMSY would also become an upper limit of fishing mortality and that the advised fishing mortality would be set at or lower than that level. WKREF2 did not discuss what to do in situations where SSB< Blim or alternative forms of HCR for the advice rule. Building community understanding and con- sensus around simplified and harmonised guidelines has yet to be achieved. A further workshop WKREF3 will be required to achieve that aim. The report includes 6 recommendations for ACOM consideration.
  • Working Group on Fisheries Benthic Impact and Trade-Offs (WGFBIT; outputs from 2021 meeting).

    Pierucci, Andrea; Nguyen Xuan, Alessandra; Kraan, Casper; Bradshaw, Clare; Garcia, Clement; Mangano, Cristina; Smith, Chris; van Denderen, Daniel; Connor, David; Punzo, Elisa; et al. (International Council for the Exploration of the Sea, 2022)
    The Working Group on Fisheries Benthic Impact and Trade-offs (WGFBIT) develops methods and performs assessments to evaluate benthic impact from fisheries at regional scale, while con-sidering fisheries and seabed impact trade-offs. In this report, new fishery benthic impact assessments are carried out for several sub-regions in the Mediterranean (Greek waters, South Adriatic Sea, Sicily waters). For other regions, updates of the whole assessment or specific steps only were presented. A standard advice sheet for the regional benthic assessments, intended as input to the next generation of the ICES Ecosystem and Fisheries Overviews, was finalised and compiled for some regions as example (Greek wa-ters, Baltic Sea). A validation of the longevity relationships using new data was executed for the Kattegat area and the Southern North Sea. In relation to the methodology, some recommenda-tions were formulated concerning the update on depletion rates, the use of epifauna- or infauna-based data, guidance on which set of epibenthic species to include and the time scale for setting the average swept-area-ratio (SAR) used in model fitting and assessment. A benchmarking pro-cess comparing available benthic impact assessment approaches for MSFD descriptor 6 “Seafloor integrity” is needed, as the WGFBIT approach (relative benthic state) is not the only way to assess benthic impacts from physical disturbances. A start was made to explore how to incorporate more explicitly ecosystem functioning in to the WGFBIT seafloor assessment methodology. An improved understanding of the relationships between total community biomass and ecosystem functioning may assist in setting acceptable thresholds for ecosystem impacts from trawling. Furthermore, an improved understanding of the link between species functional effect traits and proxies and processes for specific ecosystem functions could help increase our ability to predict the impact of fishing disturbance on benthic ecosystem functioning more accurately. The ecosys-tem function we focus on is the biogeochemical cycling of organic matter. Two approaches were discussed (i) Biological traits approach focusing on the linkage between biological traits and eco-system functions and (ii) biogeochemical modelling approach using the established the OMEXDIA model.
  • ASFA survey shows aquatic science libraries, impacted by COVID-19, are still able to help in their communities

    Superio, Daryl L.; Silvoni, Gabriela; Vicary, Tamsin (2020)
    ASFA Magazine
    Between August and October 2020, ASFA ran a survey to assess the impact of COVID-19 on aquatic science libraries around the world. With restrictions in many places library staff and patrons were unable to access buildings, we were interested to find out what impact this was having on staff and learn whether libraries were helping their communities respond to the virus. This article presents a summary of the survey results, further analysis will be undertaken by the ASFA Impact and Strategies Working Group, looking particularly at ways in which libraries can mitigate the impact of the pandemic. Librarians have many transferable skills which can be of use to local and global communities during these difficult times and it is vital we let communities know what we can offer.
  • Factors Affecting the Attendance of IAMSLIC Members at IAMSLIC Annual Conference

    Superio, Daryl L.; Anderson, Kristen L. (2016)
    A research survey was conducted to determine the factors that affect the attendance of International Association of Aquatic and Marine Science Libraries and Information Centers (IAMSLIC) members at annual conferences. Findings of related studies revealed that participants (librarians and other professionals) attend conferences for career development. Moreover, participation in a conference was affected by several factors including location, affordability, safety, and the demography of the participants. Among IAMSLIC members, networking, affordability and educational opportunities were the dominant factors in attending a conference and location was of least significance. Members of IAMSLIC attended annual conferences for the opportunity for networking with other professionals, updates on current trends and developments in the profession.

  • Responsible fish utilization

    Food and Agriculture Organization of the United Nations (Food and Agriculture Organization of the United Nations, 1998)
    These guidelines have been produced to support the implementation of the Code of Conduct for Responsible Fisheries particularly with regard to the need for responsibility in the post–harvest sector of the fish producing industry. The industry that produces fish for food has three major areas of responsibility: to the consumer of the food to ensure that it is safe to eat, is of expected quality and nutritional value,to the resource to ensure that it is not wasted andto the environment to ensure that negative impacts are minimized.In addition the industry has a responsibility to itself to ensure the continued ability of many millions of people throughout the world to earn a gainful living from working within the industry. Article 11.1 of the Code of Conduct for Responsible Fisheries and other related parts of the Code are concerned particularly with these responsibilities. This publication provides annotation to and guidance on these articles to assist those charged with implementation of the Code to identify possible courses of action necessary to ensure that the industry is conducted ina sustainable manner.

  • Fisheries management

    Food and Agriculture Organization of the United Nations (Food and Agriculture Organization of the United Nations, 1997)
    These Guidelines have been produced to support the implementation of Article 7 of the Code of Conduct for Responsible Fisheries, with some reference to Article 12. They are addressed primarily to the decision-makers within fisheries management authorities and other interest groups, including fishing companies, fishers' organizations, concerned non-governmental organizations and others. The Guidelines provide a background to the need for fisheries management and an introduction to the activities encompassed by fisheries management. They introduce the major constraints experienced in fisheries and fisheries management and some of the fundamental concepts related to these. Biological, environmental, technological, socio-cultural and economic constraints and concepts are examined. Information is fundamental to responsible fisheries management and these Guidelines put emphasis on the range of data required for informed decisionmaking and examine aspects of the collection and interpretation of these data. Data are discussed in terms of three suggested scales in fisheries management: fisheries policy and development planning, formulation of management plans and implementation of management action. The range of possible management actions is outlined. This includes technical measures, such as gear restrictions, and more direct approaches in the form of direct catch limitation or effort limitation. The problems associated with open access fisheries are explained and comments made on the means to limit access and obstacles which may be encountered in this process. Finally, the Guidelines examine the management process. This section covers the process of agreeing on a management plan for a fishery, including the need for consultation and, where appropriate, cooperative decision-making. The need for periodic review of management plans is stressed. The importance of an effective legal framework, institutional and administrative structures and monitoring control and surveillance are described. (PDF contains 91 pages)

  • Fishing guidelines

    Food and Agriculture Organization of the United Nations (Food and Agriculture Organization of the United Nations, 1996)
    In accordance with the recommendations of the Committee on Fisheries (COFI), FAO prepared the first draft of the technical guidelines in relation to Fishing Operations, which were submitted to the Technical Consultation on the Code of Conduct for Responsible Fishing, Rome, 26 September to 5 October 1994. The draft was prepared taking into account the Declaration of Cancún, Agenda 21 of United Nations Conference on Environment and Development (UNCED) and the Report of the Expert Consultation on Responsible Fishing Operations, Sidney, British Colombia, Canada, 6 -11 June 1994. Thereafter, the draft was revised taking into account, the negotiations at the UN Conference on Straddling Fish Stocks and Highly Migratory Fish Stocks, the elaboration of the Code as well as developments at the International Maritime Organization (IMO) with regard to the Protocol to the Torremolinos International Convention on Fishing Vessel Safety and the new International Convention on Training, Certification and Watchkeeping for Fishing Vessel Personnel, 1995. Technical Guidelines are given in support of the implementation of the Code in relation to fishing operations. These are addressed to States, international organizations, fisheries management bodies, owners, managers and charterers of fishing vessels as well as fishers and their organizations. Guidance is also given with respect to the general public. (PDF contains 93 pages)
  • Information and knowledge sharing

    Food and Agriculture Organization of the United Nations (Food and Agriculture Organization of the United Nations, 2009)
    The Guidelines provide a special focus on information and knowledge sharing and its current and potential role in supporting implementation of the Code of Conduct for Responsible Fisheries. They expand on relevant principles and standards set forth in the Code and make practical suggestions about ways to ensure that this role can be enhanced. The issues involved in the flow of information between different stakeholder groups include topics as diverse as information policy frameworks and information and communication technology infrastructure, hence coverage is introductory. Some of the constraints involved in the cycle from the creation, production, dissemination and availability of information and knowledge to its effective use and sharing by the present generation as well as its preservation for the future are presented. The special circumstances and requirements of stakeholders in developing countries are recognized in accordance with Article 5 of the Code. A separate chapter on small-scale fisheries and aquaculture looks in more detail at the special situation and information needs of the sub-sector. The Guidelines aim to foster a better understanding of the issues involved to ensure that stakeholders obtain the essential information that they need and that they make available their own information and knowledge for the public good.
