| Abstract: | A device is described that automatically separates and collects the feces and pseudofeces of oysters. This quantitative method allows accurate estimation of assimilation efficiency. Oysters were fed the diatom Thalassiosira pseudonana at either of two algal concentrations, 1 × 106 and 4 × 106 μm3/ml of algae. Ingestion, and fecal and pseudofecal production were greater at the higher concentration but assimilation efficiencies were not significantly different (α = 0.05). |
