- Abstract
Filtration rates (FRs) of the invasive Asian clam C. fluminea of various sizes ranging from 0.5 to 4.5 g whole-body weight were experimentally assessed under controlled laboratory conditions using two phytoplankton species of different sizes and biovolumes (Chlamydomonas reinhardtii and Pseudokirchneriella subcapitata) as food. Overall, the FRs ranged from 0 to 347 mL g−1 h−1 (median value: 52 mL g−1 h−1). We found no statistical difference (p > 0.05) between the two phytoplankton species used, nor did we find a significant relationship between individual FRs (mL individual−1 h−1) and wet weight (WW) or shell length (SL). However, we did find a significant negative relationship between FRs (mL g−1 h−1) and WW in clams fed on C. reinhardtii and P. subcapitata (FR = 131 WW−1.05 and FR = 203 WW−1.28, respectively), indicating that smaller (younger) individuals had a higher FR than larger (older) individuals in the tested range of particle size (i.e., 4–6 µm diameter). Such results highlight the strong influence of size/age on the filtration rate of C. fluminea and provide new insights to better understand the invasive capacity of this species.
