In this study, we measured the valve movements of cultivated mussels Mytilus galloprovincialis feeding on toxic A. minutum (n = 29 mussels, shell length = 67.1 ± 3.2 mm, x̅ ± SD) or a morphologically-similar, but toxin-free phytoplankton, Heterocapsa triquetra (n = 24 mussels, shell length = 68.3 ± 2.9 mm). Phytoplankton inoculations were conducted in three sequential “pulses” intended to increase microalgal cell concentrations in a stepwise manner up to ~5000 cells l−1 over a 9-h period. M. galloprovincialis was connected to a non-invasive valvometry apparatus that concurrently measured the magnitude of valve openness once every 0.1 s. It was found that M. galloprovincialis tended to keep its valves open over the course of the experiment, regardless of the phytoplankton species present in water. Standard valve opening metrics, such as the opening duration and opening amplitude, were not significantly affected by the species of phytoplankton. However, the frequency of brief and partial valve closures (microclosures) was significantly influenced by phytoplankton species (P < .01). M. galloprovincialis subjected to toxic A. minutum exhibited 20.3 ± 0.4 (x̅ ± SEM) microclosures per 3-h pulse period, whereas those exposed to the control H. triquetra exhibited 7.9 ± 0.4 (x̅ ± SEM) microclosures. This response was detectable over the 3 h following the first inoculation pulse that provided a phytoplankton concentration of 1000 cells l−1. Our findings are consistent with growing evidence that bivalves are sensitive to very low concentrations of harmful microalgae. Deploying in situ valvometry sensors with real-time monitoring capabilities may provide an early warning of harmful algal bloomsFinancial support was provided by Fisheries and Oceans Canada and the Spanish government through the Ministerio de Economía y Competitividad (projects AGL2013-45945-R and CTM2016-76146-C3-2-R)Peer reviewedElsevierMinisterio de Economía y Competitividad (España)Fisheries and Oceans CanadaConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201820182019info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/172153reponame:DIGITAL.CSIC.
