Table 1 Mytilus edulis. Shell length (L), body dry weight (W), filtration rate (F), gill area (G), and condition index (CI) of mussels measured in various studies by means of different methods. Estimated allometric power-law equations for F versus W and L, and G versus W and L are shown

From: Allometric equations for maximum filtration rate in blue mussels Mytilus edulis and importance of condition index
