In this project we hypothesize that this enhanced phytoplankton production can efficiently be exploited to mitigate algal toxicity and increase meat yield in mussels cultured for human consumption. The project will study how mussel feeding and growth performance responds to the specific environment of enhanced phytoplankton production from forced upwelling. By implementing and applying the DEB model we will study how food quantity (e.g. chlorophyll a, phytoplankton abundances) and quality (phytoplankton species), as well water temperature, can explain the variability in mussel growth. By using the DEB-based model, we expect to get new insight and explanation on the contribution from dilution processes (e.g. due to mussel growth) vs. active detoxification processes in the uptake-excretion kinetics of toxins by the bivalve.
