- Abstract
The freshwater mussel Elliptio complanata was provided green algal-dominated water from a Partitioned Aquaculture System (PAS) over a range of water temperatures (6.1–32.4 °C) and suspended particulate organic carbon (POC) concentrations (<1–32.2 mg C L−1) to determine filtration rates as mg POC kg−1 wet tissue weight h−1. The lowest filtration rates were observed at lowest temperatures and POC concentrations while the highest rates were at intermediate temperatures and the highest POC levels. The predicted filtration rate (PFR) in response to water temperature and POC concentrations was as follows: ln PFR=1.4352+0.1192 POC+0.1399 T−0.0001 T3. Within the experimental conditions, PFRs at any POC concentration increased with increased water temperature to a peak at 22 °C and then decreased. The maximum PFR occurred at 22 °C and 32 mg C L−1 and the minimum PFR at 7 °C and 1 mg C L−1. A model to describe the mussel filtration rate responses to PAS water conditions involves both water temperature and POC concentration.
