| Introduction The blue mussel (Mytilus edulis) culture occurs in temperate waters around the world under a wide range of environmental conditions, e.g. at phytoplankton concentrations below as 1-2 µg L-1 (in Norwegian fjords) up to 9-10 µg L-1 (in French Atlantic coastal sites). Under such contrasted food resources, the aim of our study is to develop a generic bio-energetic model for M. edulis, i.e. that can be applied in various contrasted environments with a constant set of parameters, to simulate growth and reproduction of the blue mussel. Such a model will allow us to assess directly the links between mussel growth performances and environmental parameters in different culture sites. |

| Objectives The objective of the study is to assess how phytoplankton composition and quantity enhanced by forced upwelling of nutrient rich deep water in a fjord affects growth performance and detoxification in cultured mussels. Sub goals are: 1. monitor the fjord environment and succession of phytoplankton including toxic algae, 2. contrast feeding and growth performance in mussels affected and unaffected by the enhanced phytoplankton assemblage forced by upwelling of nutrient rich deep water, 3. estimate elimination rate of algae toxins in mussels introduced to enhanced phytoplankton concentration forced by upwelling of nutrient rich deep water. |

| Mussel aquaculture is well developed in various ecosystems of temperate waters. In the aim of developing predictive tools for management of mussel aquaculture, a better understanding of relationships between the environmental conditions and mussel growth is necessary. For this purpose, development of bioenergetic models, linking environmental variables (especially food resource and temperature) and mussel growth and reproduction, are of a particular interest. Dynamic Energy Budget (DEB) theory offers a general framework to study energy flows in organisms, from assimilation to use for maintenance, growth and reproduction. This theory is appropriate for growth modelling of marine organisms and have first been applied in 1993 to model mussel growth.... |
