Toxic dinoflagellate <i>Prorocentrum cordatum</i> affects the filtration rate and enzymatic activities of Chinese razor clam (<i>Sinonovacula constricta</i>).

ABSTRACT: Harmful algal blooms represent a significant environmental challenge in various marine ecosystems worldwide. While marine filter-feeder bivalves can consume toxic phytoplankton, their capacity to mitigate the presence of harmful microalgae is not yet fully understood. In this study, we examined the filtration rates and enzymatic activities of Sinonovacula constricta, a commercially valuable bivalve, when exposed to varying levels of toxic dinoflagellates (Prorocentrum cordatum) and non-toxic diatoms (Skeletonema costatum) over a 12-h period. Chlorophyll a concentration was used to reflect the presence of these microalgae. In the initial 2 h, the filtration rate under toxic conditions was lower than under non-toxic conditions. However, after the first 2 h, the fi
