AbstractThe control of sea lice infestations on cultivated Atlantic salmon is a major issue in many regions of the world. The numerous drivers which shape the priorities and objectives of the control strategies vary for different regions/jurisdictions. These range from the animal welfare and economic priorities of the producers, to the mitigation of any potential impacts on wild stocks. Veterinary ethics, environmental impacts of therapeutants, and impacts for organic certification of the produce are, amongst others, additional sets of factors which should be considered. Current best practice in both EU and international environmental law advocates a holistic ecosystem approach to assessment of impacts and risks. The issues of biosecurity and ethics, including the impacts on the stocks of species used as cleaner fish, are areas for inclusion in such a holistic ecosystem assessment. The Drivers, Pressures, State, Impacts, Responses (DPSIR) process is examined as a decision-making framework and potential applications to sea lice management are outlined. It is argued that this is required to underpin any integrated sea lice management (ISLM) strategy to balance pressures and outcomes and ensure a holistic approach to managing the issue of sea lice infestations on farmed stock on a medium to long-term basis.

Herring: Linking biology, ecology and population status in the context of changing environmentsClarke, M W; Brophy, D; Dickey-Collas, M; Fiksen, O; Hatfield, E M C; Hay, D E; Nash, R D M; Norcross, B L; Slotte, A (Marine Institute, 2008)This Conference took place from 26th to the 29th August 2009 at the national University of Ireland, Galway. It was organized to link our understanding of herring biology, population dynamics and exploitation in the context of ecosystem complexity. It is beyond argument that herring play a pivotal role in shaping the structure and dynamics of many boreal continental-shelf ecosystems. As fisheries management moves towards an ecosystem approach, the time seemed right for ICES to hold another herring symposium. Since the last ICES symposia on herring were in the 1960s (ICES Herring symposium, 1961; Biology of Early Stages and Recruitment Mechanisms of Herring, 1968) many of the former paradigms have been rejected and substantial progress has been made by striking out on new avenues of thought. In addressing this particular topic, we can also follow on from the decadal herring symposia series held in North America and thus cover new research from both the ICES and PICES community. It was fitting that this conference enjoyed the support of ICES, PICES and GLOBEC. Much has changed in the world of herring, since the last ICES symposium. Stocks have collapsed, recovered, and in some cases, have collapsed again. Work in recent years has focused on the development and evaluation of management strategies for herring stocks, and this work continues. The importance of herring in the food chain is an ever present consideration. Despite the many advances in our knowledge of stock structure and biology, herring population still present a challenge in terms of managing highly variable populations. We hope that this summary report, prepared by the science committee and the conveners, accurately represents the variety of presentations and discussions on this most variable of fishes.
F-Press: A Stochastic Simulation Tool for Developing Fisheries Management Advice and Evaluating Management StrategiesCodling, E.; Kelly, C. (Marine Institute, 2006)F-PRESS is a stochastic simulation tool based on a simple algorithm designed to fit in with the ICES conceptual framework for software development. F-PRESS can be used to develop probabilistic assessment advice or to evaluate management strategies or harvest control rules (HCRs). In this paper, we describe and justify the underlying methodology on which F-PRESS is based and give full details of the modular structure of the simulation algorithm. We use the example of Irish Sea cod to demonstrate how the software can be used to develop probabilistic management advice or to evaluate and compare different HCRs.
21st century fisheries management: a spatio-temporally explicit tariff-based approach combining multiple drivers and incentivising responsible fishingKraak, Sarah B. M.; Reid, David G.; Gerritsen, H.D.; Kelly, Ciarán J.; Fitzpatrick, Mike; Codling, Edward A.; Rogan, Emer (Oxford University Press, 2012)Traditionally fisheries management has focused on biomass and mortality, expressed annually and across large management units. However, because fish abundance varies at much smaller spatio-temporal scales, fishing mortality can potentially be controlled more effectively if managed at finer scale. The ecosystem approach requires more indicators at finer scales as well. Incorporating ecosystem targets would need additional management tools with potentially conflicting results. We present a simple, integrated, management approach that provides incentives for “good behaviour”. Fishers would be given a number of fishing-impact credits, called real-time incentives (RTIs), to spend according to spatio-temporally varying tariffs per fishing day. RTI quotas and tariffs could be based on commercial stocks and ecosystem targets. Fishers could choose how to spend their RTIs, e.g. by limited fishing in high-catch or sensitive areas or by fishing longer in lower-catch or less sensitive areas. The RTI system does not prescribe and forbid, but instead allows fishers to fish wherever and whenever they want; ecosystem costs are internalized and fishers have to take them into account in their business decisions. We envisage no need for traditional landings or catch quotas for the fleets while operating under the scheme. The approach could facilitate further devolution of responsibility to industry.
