SEAwise Report on scoping workshops

The SEAwise stakeholder integration aims to ensure that the key issues of relevance, current ecosystem status, potential management measures are identified and prioritised for further evaluation in the project and hence that the end results are relevant to the end users. This deliverable report describes the approach taken to identify the stakeholder community, stakeholder interests and responsibility and subsequently establish ecological and social system priorities. The SEAwise consultations in the first half year of the project had the specific aims to identify key stakeholders, build trust and common understanding between SEAwise scientists and these stakeholders, identify key issues of relevance for ecosystem based fisheries advice, current ecosystem status and potential management measures, identify priorities of these key issues and evaluate how this varies between consultation methods and regions. Stakeholders were contacted through the Mediterranean Advisory Council (MEDAC), Southwestern Waters Advisory Council (SWWAC), Northwestern Waters Advisory Council (NWWAC), North Sea Advisory Council (NSAC). Pelagic Advisory Council (PELAC) and Baltic Sea Advisory Council (BSAC). Scientists participating in the project completed the same exercises for comparison. The choice of consultation method was chosen to enhance equal influence of all participants by minimising the impact of the organising scientists’ expectations and emergent group dynamics on group results. Three different approaches were used (individual consultation: 79 contributors, individual consultation in a group environment: 106 contributors and group consultation: 106 contributors). In total, 2752 key issues were identified. Six issues were identified repeatedly across regions and participant groups: climate change, MPAs, windfarms, employment and small scale fisheries. The remaining words often were identified only by either SEAwise scientists or stakeholders and there were frequent instances where one of these group identified a word in the top 10 whereas the other group did not mention the word. The results highlight the importance of scoping the key topics beyond the scientists participating in the project and the need to consider consultation methods thoroughly. Moving forward in SEAwise, the individual scoping results will be used to identify issues which interested users may first search for and the workshop cloud scoping together with the individual scoping results to identify key topics for advice. The differences between SEAwise participant and stakeholder key topics will be used in the project to raise awareness of the need to talk to end users about the advice produced in advance.

SEAwise Report on key drivers and impacts of changes in spatial distribution of fisheries and fished stocks

   An ecosystem approach to fisheries management requires the consideration of spatially explicit management measures and other impacts on species and the links between the distribution of fished species, their surrounding environment and productivity. Quantification of the spatial aspects of fisheries and ecology of commercially fished stocks may improve the accuracy of the predicted changes in fish productivity, fisheries yield and costs, benefits and selectivity.  To provide a knowledge base for spatially explicit considerations, SEAwise consulted stakeholders throughout Europe and conducted a systematic review of the scientific literature. As a first step, engagement with relevant stakeholder groups in each Case Study identified key issues of relevance to spatial management. The input from this stakeholder consultation was supplemented by a systematic literature review with careful consideration of the objectives, search terms, inclusion/exclusion criteria, the method for data/knowledge extraction and ultimately how these data and knowledge will be used. The purpose of the task was to quantify the key drivers and pressures behind the changes occurring in commercial fish stocks and fisheries distribution that have a spatially explicit content, map the relevant existing scientific knowledge and provide input to the subsequent SEAwise tasks.  The words identified by the stakeholders consulted focused on factors causing changes to the distribution of commercial fish/shellfish (climate change, MPAs, species interactions, pollution, habitats and invasive species) and fisheries (windfarms, MPAs, Marine spatial planning) as well as the other human impacts. The systematic review extracted data from 331 papers. The most frequently studied topic was the distribution of fish and the region with most papers was the North Sea with about the twice the amount of papers in each of the other regions. The most frequently studied species in the literature were cod, hake and plaice and by far the most frequently studied fisheries was demersal trawl fisheries.  Among the issues identified by stakeholders as key, the effects of environmental conditions on the distribution of fish were particularly well represented in the reviewed material. In contrast, factors determining the distribution of fisheries were almost exclusively studied in trawl fishing in the North Sea and papers on the effect of area restrictions on fish and fisheries were largely restricted to Western waters and the North Sea. While knowledge on the effects of habitats on species did exist, this was restricted to the Baltic Sea and North Sea and papers addressing this outside these areas were close to non-existent. This points to important areas for future work in SEAwise. This report describes part of the results of the SEAwise project.

SEAwise Report on the key social and economic aspects of regional fisheries

Fishing is a human activity with various social and economic implications. In most countries, those implications are key factors to consider when deciding on specific management strategies. In this report, the fisheries management strategies implemented in the different European marine regions are reviewed, and relevant indicators, models and tools that can be used to predict the effectiveness of these strategies, from a social and economic point of view are identified. The objective was to identify the critical social and economic aspects of fisheries,  relevant social and economic indicators, and regionally‐relevant management measures to be considered in the evaluations of different management strategies later in the project.   The scoping consultations and systematic reviews identified a long list of potentially relevant key social and economic aspects and management measures. Among these, the most frequently mentioned items identified in scoping with stakeholders were windfarms, employment/jobs, MPAs, food supply, small-scale fisheries, local communities and pollution. The systematic review identified landings (volume or value), effort (days at sea), fuel costs, number of vessels, profit, aspects of costs, economic performance, sustainability-resilience, compliance and capacity as frequently occurring topics. The fisheries management policies most frequently mentioned were effort control, landing obligation, Individual Transferable Quota (ITQ), MPAs and TAC. Among the papers analyzed, more than 30%, concerned the Mediterranean region, followed by Western Waters, the North Sea and the Baltic Sea, indicating a higher contribution of Mediterranean studies to the conclusions. Aspects identified frequently in both scoping and in systematic reviews included MPAs and small-scale fisheries, which were all identified in both methods as frequently occurring. However, there were also aspects which appeared to be represented differently in the evaluations (e.g. employment and local communities) indicating discrepancies between the available knowledge and that sought by the end users.

SEAwise Report on the key drivers of stock productivity and future environmental scenarios

An ecosystem approach to fisheries management requires the consideration of commercial species as components of an ecosystem and the acknowledgement of the links between their productivity and the surrounding environment. To provide a knowledge base for such links, SEAwise consulted stakeholders throughout Europe and conducted a systematic review of the scientific literature. The systematic review resulted in 2050 articles from the literature search that were screened for their tile and abstract. 516 of them were retained for data extraction. The majority of studies were conducted in the Baltic Sea and the North Sea, followed by the Western Waters, and with only a few dozen papers in the Mediterranean Sea. Cod and herring were the most studied species, temperature and more generally climate and hydrodynamics indicators were the main drivers investigated, and reproduction was the main productivity-related process. The output of the systematic review is a database of scientific articles organised by regions, species, environmental drivers and productivity-associated processes and where outcomes, but also spatial and time scales, analytical methods etc. are described in a standardised fashion. This database will be analysed in the coming months and used in the downstream tasks of WP3. The most frequently driver identified by stakeholders across regions was climate change followed by species interactions, cod, pollution, commercial fish/shellfish and plankton. Climate change effects on stocks through temperature and salinity are relatively well covered in the literature as are effects of plankton and species interaction. Studies of the effects of pollution do not occur frequently and as a consequence require a dedicated effort is made in SEAwise to remedy this. Species reported frequently by the stakeholders included cod, seabass, sardine, sole, crabs, flatfish, Norway lobster, octopus, shrimps, herring, sprat, anchovy, hake, new species (species increasing in abundance as a result of climate change as well as invasive species of commercial interest) and sandeel. Among these, more than 10 papers were retrieved for cod, sardine, sole, herring, sprat, selected flatfish, anchovy, hake and sandeel. For the remaining species, a dedicated effort must be made in SEAwise if they are to be included in stock models.  This report describes results of the SEAwise project.
