6 - Description du projet
Objectif scientifique et/ou technologique de la collaboration
The utilization of the Norwegian coastal zone is rapidly increasing and the aquaculture industry faces the challenge of competing for space with other users. Farming and sea ranching of suspension feeding shellfish is a growing industry in Norway (approx. 580 licenses are given). The production of mussels (Mytilus edulis) has increased from a level of less than 500 metric tons per year during the last two decades to 4-5000 tons in resent years. The development of sea ranching of scallops (Pecten maximus) has been prompted by the new Act on sea ranching, since this has launched a substantial increase in seabed areas for culture. There is also increased interest in flatoyster (Ostrea edulis) farming. The expected expansion of mussel farming has been hindered primarily by harvest closures due to toxic algae, low meat content partially caused by high-density mussel stocks, and post harvest logistic factors, which all interact. However, recent structural and competitive improvements in the industry have demonstrated that development will proceed and a substantial increase in biomass is expected. To effectively take the advantage of available areas it is thus necessary to realize Norway's potential for aquaculture. In this context the carrying capacity is crucial. This requires scientific knowledge on ecological interactions related to bivalve production, both on carrying capacity estimations and measures for localization of farming. This knowledge concerns the interactions between bivalve and environment. Growth of suspension-feeding bivalves is largely controlled by food supply, which is affected by seston concentration and composition as well as seston transport rate (Frechette et al. 1989). Food supply is also linked with phytoplankton dynamics (Rosenberg and Loo 1983, Smaal and Stralen, 1991). Suspension feeders such as mussels have a remarkable capacity to filter the water column and to deplete the water of seston, and in culture they may be food limited at high density (Navarro et al. 1991, Strohmeier et al. 2005). Based on the studies on how farm design reduces current speed, deplete food particles and influences carrying capacity mussel farms (Strohmeier et al. 2005; Aure et al. 2007), IMR research group has together with The modelling group at Department of Biology at the University of Bergen started to establish modelling capacity within shellfish aquaculture. To achieve high quality shellfish and to select new suitable farming sites (or expand existing farming sites) it is clear that the stocking density at which production levels are maximized without negatively affecting growth rate has to be determined (Carver and Mallet 1990). This objective can be achieved by developing mathematical models as a basis for management tools. They need to include processes at individual/eco-physiological level, farm/population level and ecosystem level (Beadman et al. 2002). Individual models have been addressed recently with generic models based on Dynamic Energy budget concepts (Ren and Ross, 2005; Pouvreau et al. 2006; Bacher and Gangnery, 2006 ; Casas and Bacher, 2006) and these tools are proposed as a contribution to the development of carrying capacity models in Norwegian coastal waters. Three levels of modelling are considered. The basic operation of the Fjord model NORWECOM is implemented for the Lysefjord and Hardangerfjord (Asplin et al., 2004) and will provide the current velocity, primary production, phytoplankton concentrations, etc in the fjord for various situations, necessary to force the Farm model and the Mussel model. The Mussel model will be based on existing models (DEB model), developed for mussels in suspended culture in low seston environments using data from on-going work in Norway. The model will be a module of Farm model, in suspended culture and subsequently for scallops in sea ranching, which simulates seston flux according to farm design (i.e. length / width relation and spacing between long-lines).

Programme de travail proposé et calendrier
In order to implement, validate and apply the carrying capacity model to mussel farms in Norwegian fjords, tasks will consist in: · Adapting and implementing the ecophysiology DEB model for mussels using Norwegian datasets. · Calibrating the Mussel model to low seston conditions and validate the model simulations on data collected from mussel farms and production areas. · Coupling existing models: the Fjord, Mussel, Farm models · Training scientists to the use of the models through its implementation in easy to use simulation software, and help therefore to convert model outputs into recommendations for shellfish farmers. Data needed to calibrate and validate the models will be collected by the Norwegian partner within the on-going CANO (Carrying capacity in Norwegian aquaculture) funded to IMR by the Research Council of Norway (2006-2009). This includes data on temperature, seston concentration, nutrients, and laboratory experiments on the filtration by mussels, measurements of mussel growth (dry weight, shell length) during one year at one site. Within the MOMA project, modelling tasks will be achieved through workshops on modelling training and implementation twice a year during 2 years, while specific developments and tests will be carried out in the meantime, using electronic communication to exchange data and results. The timetable of the corresponding tasks is detailed below: · Months 1-3: exchange of data sent by IMR to IFREMER in order to test the individual model of mussel ecophysiology · Month 4: workshop in Norway to discuss the results of the mussel model (one week), calibrate the model on measured growth data and to train partners from IMR using STELLA simulation software · Month 5-9: test of the individual model using datasets provided by the NORWECOM ecosystem model in order to assess the differences in mussel growth at different locations. The model will provide the current velocity, primary production, phytoplankton concentrations, flagellate/diatom composition, detritus in the fjord for various situations, necessary to force the mussel model. Datasets will be sent by IMR partners to IFREMER who will test the mussel model · Month 10: workshop in France to discuss the new results, transfer the code to IMR and plan the work on the coupling between the ecosystem and mussel models · Month 11-17: coupling of the mussel and ecosystem models. IMR partners will implement the mussel model into the NORWECOM model and IFREMER will develop the farm model, coupling transport and mussel models at a small scale. Both models will be applied to the fjord selected and documented in the CANO project · Month 18: workshop in Norway to discuss the results of ecosystem/mussel and farm models. Scenarios to apply the models will be proposed and discussed. Publications in scientific journals will also be planned for the final 6 months of the project · Month 19-23: simulations of scenarios: locations of farms in the selected fjord, density of mussels and size of the farm, application to several time series of driving functions in order to reflect inter-annual variability. Drafts of scientific papers will be started · Month 24: final workshop in France. Discussion of the results, drafting and editing of the scientific paper
Intérêt de la collaboration et complémentarité des équipes
Ifremer has been applying DEB models for the past 2 years for a variety of species (oysters, mussels, cockles) and ecosystems (Baie du Mont Saint Michel, Baie des Veys, Etang de Thau, Bassin de Marennes-Oléron, Bassin d'Arcachon) and look for applying these generic models to other ecosystems for environmental and aquaculture issues. IMR will provide the data to test the DEB model (mussel growth, environmental parameters) and the Fjord model NORWECOM will yield the inputs to the DEB model which will be embedded in the Farm model and used to estimate the effect of rearing strategy on mussel growth. This project is therefore an opportunity to test the model on new datasets corresponding to northern ecosystems with different environmental conditions (temperature, food concentration). It is also of great interest to assess carrying capacity in other ecosystems in order to develop and implement generic tools that can be used by managers to assess site suitability for shellfish aquaculture. This issue is a common concern of both partners and has been raised by several countries as a need in the framework of aquaculture sustainability (e.g. Canada, China, New Zealand, Ireland). In combination with the CANO (Carrying capacity in Norwegian aquaculture) project funded by the Norwegian authorities, the collaboration will therefore generate a core group of scientists capable to address carrying capacity issues. Expertise of scientists are also complementary. Participants from Ifremer have been involved in ecophysiological and modelling projects dealing with carrying capacity and aquaculture challenges. Participants from IMR have a well known expertise on the interactions between aquaculture and environment.
Avantages de la collaboration pour le laboratoire français
Ifremer and IMR have signed an agreement in May 2006, and the topic on "Localisation and environmental impact of aquaculture activities" is mentioned in the list of collaborative works. This project is directly linked to this topic and is therefore part of Ifremer strategy to establish collaboration with IMR in the aquaculture area. Besides, the project has no risk of failure because of quality of scientists involved in both sides and it will contribute to disseminate and acknowledge Ifremer expertise in carrying capacity assessment, one of the hot topic in aquaculture faced to sustainability issues.

Résultats attendus du projet
(Publications, communications, organisation de colloques, formation, valorisation économique, sociale, industrielle, dépôt de brevet)
Expected results are the following: * we will improve and validate the ecophysiology model for mussels, as a generic tool applicable to any site at the scale of a farm or an ecosystem. This is not only true for Norwegian coastal waters, and the model will be applied to other ecosystems in France. This is a very important step in the applicability of robust models for shellfish aquaculture. It also has implications in term understanding and assessing the environmental factors limiting or enhancing mussel growth. * By definition the type of model developed in the project is also applicable to other shellfish and fish species. Our results will therefore support other projects dealing with other farmed species * we will design and implement friendly modelling tools for the ecophysiology and the farm models, applicable to Norwegian and French aquaculture sites, and these tools will be used to demonstrate and predict the carrying capacity for shellfish farming, e.g. growth of mussels depending on mussel density, site location, environment variability * we will publish our results in high rated international and applied scientific journals * through training, we will extend our capacity to adress carrying capacity issues in Norway and France
