  Citation × Citation Citation Abstract Copy Title: Positioning Fisheries in a Changing World Author: Grafton, Quentin, Squires, Dale, Williams, Meryl, Ridgeway, Lori Society has agreed on the goal of sustainable fisheries but achieving the goal is often submerged by more immediate national and international demands causing fisheries to slip down the political agenda or diverting attention to other fisheries issues, e.g., profitability under high fuel prices. Among the problems challenging marine capture fisheries are increasing demands for fish, uncertainty from overfishing and illegal fishing, competition for resources among different fisheries gears and methods, degrading and climate-affected ecosystems, depleted fish stocks, economic rent drains and social hardships. Solutions to these challenges, however, are available for some fisheries. Even when solutions are available, the blockages to the transition to sustainable fisheries are information failures, transition costs, use and non-use conflicts and the capacity to implement and enforce management. This paper discusses how fisheries experts can help make the case for the transition to sustainable fisheries, drawing on suitable tools that can overcome the key blockages. Within governments, fisheries should be subject to a whole-of-government approach, as fisheries ministries do not have access to all the tools to achieve a transition to sustainability. Further, transitions to sustainability are not one-off events - constant adjustments are needed to position fisheries to internal and external changes.

  Citation × Citation Citation Abstract Copy Title: Incorporating Habitat Dynamics into Bioeconomic Model of Fishery. Application to Artificial Reefs Author: Cartigny, Pierre, Ami, Dominique, Udumyan, Narine In this paper the emphasis is put on an important aspect of renewable resource use that was disregarded until now. It is the evolution of environmental carrying capacity which is traditionally interpreted as a maximal population level that can be supported by the environment (or by habitats of which it consists). Hence we adapt the Gordon-Schaefer model with constant carrying capacity by incorporating time-dependent carrying capacity that determines the state of habitats. They are subject to some biological processes (habitat rehabilitation) as well as to human aggressions (in particular habitat degradation due to fishing). Based on the developed model, we reassess the recommendations considered as a benchmark for resource managers until recently. Under simple hypotheses on the form of habitat (carrying capacity) dynamics, the current study has shown the importance of the latter for the design of management tools. When dynamic patterns of habitats are not taken into account, fishery recommendations based on Gordon-Schaefer model can be aberrant and lead to the collapse of the fishery. The presented model allows not only to enrich the design of management tools but also to assess the performance of artificial reefs, a promising ecosystem-based tool widely used in some coastal areas. The economic benefits of artificial reefs are still not well studied and represent a challenge to take up. Since artificial reefs are conceived as replacement for natural habitats, they assume the same role as these latter. Therefore the structure of our model seems appropriate to evaluate this particular management tool. Title: Incorporating Habitat Dynamics into Bioeconomic Model of Fishery.

  Citation × Citation Citation Abstract Copy Title: Evaluating the Social Costs of Fishing Activities in A Deliberative Perspective Author: O’Connor, Martin, Failler, Pierre, Johnson, Pierre W., Chamaret, Aurélie, Ferraro, Gianluca, Douguet, Jean-Marc The ECOST project aims to develop a new approach for the evaluation of fishing activities and policies in order to contribute to a better management of aquatic resources which affect sustainable development in coastal zones around the world. It has to be seen from the wider perspective of equipping public decisionmakers and society with the appropriate tools and methods needed to take into account, not only immediate economic and social profits, but also the costs engendered by fishing activities, which relate as much to ecosystems as to societies. The novelty and originality of the suggested approach doesn’t rely on the concept chosen for the analysis, the social cost, but on the way it is built and mobilised to deliberate on the evaluation of fishing activities. As Fisheries activity is a complex system, characterized by reciprocal interactions between fisheries activity and the harvested resource, it is difficult to define the effects of such activities in the society. The social cost is thus defined as an articulation between the frontiers of what is feasible? and the assessment of members of the society concerning what will be judged desirable? (O’Connor 2004). We propose an evaluation process defining the performance issue related to fishery metiers, a set of indicators and a method to assess the social cost using the Kerbabel Deliberation Matrix framework.

  Citation × Citation Citation Abstract Copy Title: Towards Behavioural Models of Fleet Dynamics Author: Hamon, Katell G., Kulmala, Soile, Thébaud, Olivier, Van Putten, Ingrid, Hutton, Trevor, Dowling, Natalie, Pascoe, Sean Considerable attention has been applied to the development of models explaining how fish stocks change over space and time, from relatively simple stock-recruitment relationships to ecosystem models with a complex food web structure. However, in many case studies fishing effort is assumed to be exogenous and even in dynamic models pre-determined by external factors such as management. An increasing number of operational bio-economic models for the marine environment are including a fleet dynamics component, recognising that fishers respond to changing environmental and economic conditions. These models are based on different assumptions about behaviour. In this review, we examine models of fisher behaviour that are empirically or theoretically developed and tested. In particular, we focus on the range of different economic and social drivers and their relevance to different types of behaviour. We find that economic factors are a dominant driver included in many types of short term behavioural models, although we acknowledge and find that other social factors play a significant role in some types of behaviour. The link between management and economic impacts is reasonably well established, and most bioeconomic models are able to incorporate these feedback systems. Incorporating these other social-dependent behaviours into bioeconomic models, however, is likely to remain a challenge unless links between management and changes in the social drivers are developed.
