Table 1

Mytilus edulis. Start and end dry weight of soft parts ( and ), mean filtration rates (), steady-state concentrations of microalgal cells (), actual measured growth rates (), and weight specific growth rates () during laboratory and field experiments. Number of mussels () used for individual measurements of shell length (), dry weight of soft parts (), and for biochemical analysis (). Values indicate means S.D.
