    Beschreibung: The ICES Study Group on the North Sea Benthos Project 2000 undertook to integrate recent (1999–2002) macrobenthic infaunal and environmental data from various national sources. The main aim was to compare the outcome with that of the ICES North Sea Benthos Survey conducted in 1986, to identify any significant changes and their likely causes. In the process, the exercise yielded valuable lessons for the conduct of international collaborative programmes, as well as insights into the utility of a range of interpretational tools. These are timely in view of increasing requirements for periodic sea-wide assessments of quality status to meet international obligations, such as those under OSPAR, ICES, HELCOM, and EU auspices for European waters. This paper provides an overview of the work which, in contrast to the 1986 survey, was more reliant on the opportunistic gathering of existing data from various sources. This presented special challenges for locating willing contributors, and then for combining and managing the sources effectively, a task which was greatly facilitated by dedicated data management support. The range of interpretational approaches aimed at evaluating spatial patterns and changes over time are summarised and the overall conclusions are presented. North Sea benthic communities appear to exhibit traits both of resilience and adaptability over different scales but continue to be structured by predominantly natural forces. Finally, lessons learnt from the ICES NSBP 2000 initiative are reviewed, and recommendations are made for the conduct of future surveys on comparable scales in the North Sea and elsewhere.

    Beschreibung: Over the past two decades, cephalopod molluscs have attracted increased attention from marine biologists and fishery scientists. Several species are important for European fisheries, as targets of small‐scale coastal fisheries and/or as bycatch in multispecies fisheries for demersal fish. The present report draws on a series of reviews prepared in 2005 for the CEPHSTOCK project (see Section 1). The taxonomy of the main resource species is reviewed (Section 2), and brief descriptions of each species are provided, along with information from studies of population genetics, habitat requirements of paralarvae and adults, and health and ecotoxicology (Section 3). The main fisheries are described, including illustration of gears used in specialized small‐scale fisheries and a discussion of the socio‐economic importance of the fisheries. The current status of cephalopod aquaculture is reviewed, highlighting notable advances in commercial culture of octopus and cuttlefish (Section 4). Current fishery data collection and fishery management are described, noting that there is no setting of landings quotas and no routine assessment of stock status. Options for stock assessment are discussed, drawing on one‐off assessments made during specific projects and current practice elsewhere in the world. The “live fast, die young” lifehistory strategies of cephalopods present particular challenges, but parallels can be drawn with short‐lived fish (Section 5). Finally, the report looks to the future, reviewing possible effects of climate change on cephalopods. It discusses the future development of aquaculture and fisheries for cephalopods, including prospects for fishery forecasting and fishery management – especially in relation to the small‐scale directed fisheries. Various knowledge gaps are identified, and ideas for research to fill these gaps are presented.

    Beschreibung: The approach to fisheries termed “balanced harvesting” (BH) calls for fishing across the widest possible range of species, stocks, and sizes in an ecosystem, in proportion to their natural productivity, so that the relative size and species composition is maintained. Such fishing is proposed to result in higher catches with less negative impact on exploited populations and ecosystems. This study examines the models and the empirical evidence put forward in support of BH. It finds that the models used unrealistic settings with regard to life history (peak of cohort biomass at small sizes), response to fishing (strong compensation of fishing mortality by reduced natural mortality), and economics (uniform high cost of fishing and same ex-vessel price for all species and sizes), and that empirical evidence of BH is scarce and questionable. It concludes that evolutionary theory, population dynamics theory, ecosystem models with realistic assumptions and settings, and widespread empirical evidence do not support the BH proposal. Rather, this body of evidence suggests that BH will not help but will hinder the policy changes needed for the rebuilding of ecosystems, healthy fish populations, and sustainable fisheries.
