Table 2 Mytilus edulis (Great Belt)

From: Effect of salinity on filtration rates of mussels Mytilus edulis with special emphasis on dwarfed mussels from the low-saline Central Baltic Sea

  Group I (L = 29.8 ± 0.4 mm) Group II (L = 29.6 ± 0.4 mm)
S 25 (psu) 25.2 ± 0.9 25.7 ± 0.2
F 25 (ml min−1) 29.8 ± 2.7 21.9 ± 0.8
S 7 (psu) 6.6 ± 0.2 7.3 ± 0.4
F 7 (ml min−1) 7.4 ± 1.4 1.8 ± 1.2
  1. Mean individual filtration rates (F 25 and F 7) measured in 2 groups of 20 mussels (I and II) with nearly same shell length (L). The filtration rates were initially measured at salinities around 25 psu (S 25) and subsequently measured again after 2 days acclimation to about 7 psu (S 7). ±SD indicated
