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.

Climate Change Influences Carrying Capacity in a Coastal Embayment Dedicated to Shellfish Aquaculture

A spatially explicit coupled hydrodynamic-biogeochemical model was developed to study a coastal ecosystem under the combined effects of mussel aquaculture, nutrient loading and climate change. The model was applied to St Peter's Bay (SPB), Prince Edward Island, Eastern Canada. Approximately 40 % of the SPB area is dedicated to mussel (Mytilus edulis) longline culture. Results indicate that the two main food sources for mussels, phytoplankton and organic detritus, are most depleted in the central part of the embayment. Results also suggest that the system is near its ultimate capacity, a state where the energy cycle is restricted to nitrogen-phytoplankton-detritus-mussels with few resources left to be transferred to higher trophic levels. Annually, mussel...
