“…These findings are consistent with earlier modelling studies (e.g., Pelletier and Magal 1996;Horwood et al 1998;Drouineau et al 2006;Dunlop et al 2009). In general, spawning MPAs were found to have limited effects (Grüss 2012), no positive effect (Hussein et al 2011) or negative effects (Edwards and Plaganyi 2011) on the SSB of temperate migratory fish populations, essentially due to fishing effort redistribution on juveniles.…”

“…It takes into account fishers' behaviour in response to management measures. Drouineau et al (2006) used ISIS-FISH to investigate the consequences of an MPA aimed at protecting hake (M. merluccius) spawners for the French Norway lobster (Nephrops norvegicus)-hake mixed fishery of the Bay of Biscay. The authors found that an MPA in the hake spawning zone had limited conservation and fisheries effects.…”

-Marine protected areas (MPAs) are increasingly being considered and used for the management of fisheries targeting mobile fish populations. Here, the recent modelling literature on MPA effects for mobile fish populations and their fisheries is reviewed. Modelling studies conducted since 2011 have filled a considerable number of knowledge gaps on the impacts of MPAs for species exhibiting home-range behaviour, nomadic movements or behavioural polymorphism, and on the effects of "targeted MPAs", which aim to protect relatively small areas where migratory fishes spend an inordinate fraction of time or are highly vulnerable to fishing (e.g., nursery or spawning zones). Also, in recent years, two studies investigated the consequences of MPAs targeting highly migratory (tuna-like) fish populations for the first time in the history of MPA modelling. Recent modelling studies found that MPAs aimed at protecting mobile species may have positive conservation effects under a relatively wide range of situations, but may generate long-term fisheries benefits only under a very limited set of conditions. In particular, MPAs were not found to be beneficial for the fisheries targeting highly migratory populations. Strategies producing both conservation and fisheries benefits were identified, which depend on fish movement patterns and numerous aspects of fish life history and fisheries dynamics. However, in view of the diversity of fish movement patterns in MPA systems and current dynamics in resource management, it is clear that additional modelling work is needed to fully understand how protected areas affect mobile fish populations and their fisheries and to be able to implement pertinent MPAs. In particular, future modelling studies should systematically assess the effects of MPAs in relation to other management tools to find strategies that are most effective in meeting management objectives, and explore the impacts of "dynamic" MPAs that follow highly migratory fish populations in space and time.

“…Consider the European hake (Merluccius merluccius) and Norway lobster (Nephrops norvegicus) mixed-fishery in the Bay of Biscay, where haketargeting métiers may be distinguished from Norway lobstertargeting ones (Drouineau et al 2006). For this case study, it could be investigated whether increasing the constraints on hake fishing would lead to a decrease in the overall fishing effort, an inflated re-allocation of fishing effort towards Norway lobster fishing, or both.…”

-Managing adequately the exploitation of commercial species subject to technical interactions is a key step towards the ecosystem approach to fisheries. We evaluate here, using a bio-economic modelling approach building on the ISIS-Fish simulation platform, the relative impact of total allowable commercial catches (TACC) and of taxes applicable to over-quota landings (deemed value) on the sustainability of a selection of species exploited by the New Zealand hoki (Macruronus novaezelandiae) fishery. We investigate some aspects of the hoki mixed fisheries, consisting of four fleets and nineteen métiers, by considering the technical interactions between hoki and Southern hake (Merluccius australis). The dynamics of effort allocation were modelled using gravity model, using value per unit of effort (VPUE) as attractivity coefficient. Several management scenarios, based on different levels of TACC, effort limits and deemed value have been defined. The impact of these strategies on spawning biomass and catches has been investigated. The results confirm that the deemed value may, in combination with TACC, be an efficient management tool. By increasing the hoki deemed value, we could somehow limit the decrease in the hoki TACC needed to harvest Western hoki sustainably. Constraining hoki fishing also restricts Southern hake fishing in the Chatham Rise and in the West Coast South Island, but leads to increased targeting of this species in the Sub-Antarctic area. The relative costs of renting/buying quota or paying the deemed value are most constraining when the hoki TACC is at relatively low level and when the hoki deemed value is more than 1.5 times the current value.Key words: Fleet dynamics / New Zealand hoki fishery / Deemed value / Fisheries management Résumé -La gestion adéquate de l'exploitation d'espèces commerciales sujettes à des interactions techniques constitue un premier pas dans la direction de l'approche écosystémique des pêches. Nous évaluons ici, au moyen d'une approche de modélisation bio-économique s'appuyant sur la plate-forme de simulation ISIS-Fish, l'impact relatif du total admissible de captures commerciales (TACC) et de taxes appliquées aux débarquements « hors quota » (taxes sur leur valeur estimée), sur la conservation d'une sélection d'espèces exploitées par la pêcherie de hoki (Macruronus novaezelandiae) néo-zélandaise. Nous étudions certains aspects de la pêcherie mixte de hoki, représentée par quatre flottilles et dix-neuf métiers, en considérant les interactions techniques entre le hoki et le merlu austral (Merluccius australis). La dynamique de l'allocation de l'effort de pêche a été modélisée en utilisant un modèle de gravité, dans lequel la valeur par unité d'effort (VPUE) représente le coefficient d'attractivité. On a défini plusieurs scénarios de gestion, basés sur différents niveaux de TACC, de limitation d'effort de pêche et de la taxe. L'impact de ces stratégies sur la biomasse féconde et les captures a été étudié. Les résultats confirment que la taxe, combinée avec les TA...

Integrated ecological–economic fisheries models—Evaluation, review and challenges for implementation

Marine ecosystems evolve under many interconnected and area-specific pressures. To fulfil society's intensifying and diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning and broader-scope management of marine resources is necessary. Integrated ecological-economic fisheries models (IEEFMs) of marine systems are needed to evaluate impacts and sustainability of potential management actions and understand, and anticipate ecological, economic and social dynamics at a range of scales from local to national and regional. To make these models most effective, it is important to determine how model characteristics and methods of communicating results influence the model implementation, the nature of the advice that can be provided and the impact on decisions taken by managers. This article presents a global review and comparative evaluation of 35 IEEFMs applied to marine fisheries and marine ecosystem resources to identify the characteristics that determine their usefulness, effectiveness and implementation. The focus is on fully integrated models that allow for feedbacks between ecological and human processes although not all the models reviewed achieve that. Modellers must invest more time to make models user friendly and to participate in management fora where models and model results can be explained and discussed. Such involvement is beneficial to all parties, leading to improvement of models and more effective implementation of advice, but demands substantial resources which must be built into the governance process. It takes time to develop effective processes for using IEEFMs requiring a long-term commitment to integrating multidisciplinary modelling advice into management decision-making. K E Y W O R D Sbio-economic models, comparative model evaluation, fisheries management advice, integrated ecological-economic fisheries models, marine spatial planning and cross-sector management, performance criteria and scales and risks, use and acceptance and implementation and communication and flexibility and complexity | INTRODUCTIONThere is a growing need for tools to evaluate policies and assess tradeoffs in management of marine resources and provision of ecosystem services such as fishing, aquaculture, renewable energy, shipping, conservation and recreation (Cormier, Kannen, Elliott, & Hall, 2015;Degnbol & Wilson, 2008;EU 2014;Langlois, Fréon, Steyer, Delgenés, & Hélias, 2014;White et al., 2012). It is necessary to elaborate and apply common principles and broader, interdisciplinary management evaluation in the use of marine space involving several types of activities and sectors Soma et al., 2013;Stelzenmüller et al., 2013;Sundblad et al., 2014). Policymakers need to know the costs and benefits of conserving ecosystem goods and services to manage them sustainably. Moreover, according to an ecosystembased approach to management, specific pressures, associated uncertainties and risks need to be taken into account (Douvere, 2008;Ehler & Douvere, 2009;Gi...
