Seasonal physiological and carbon‑related measurements of suspension feeders (Mytilus edulis and Balanus crenatus) from laboratory experiments in the Belgian marine environment

UNDER EMBARGO - This dataset contains seasonal physiological measurements from controlled laboratory experiments on two dominant suspension-feeding species expected to colonise floating offshore structures: the blue mussel (Mytilus edulis; AphiaID 140480) and the wrinkled barnacle (Balanus crenatus; AphiaID

106215). The measured parameters include clearance rates, respiration rates, faecal pellet production rates, and faecal pellet sinking velocities. Mussels were collected from an aquaculture longline at the Westdiep SeaFarm, while barnacles were manually retrieved from the intertidal beachhead at Raversijde (Oostende, Belgium). All experiments were conducted using natural seawater collected from offshore sites in the Belgian part of the North Sea. Measurements were repeated across multiple seasons to capture temporal variability in physiological performance. The dataset was produced within the SWiM and EcoMPV projects and is suitable for reuse in ecosystem and biogeochemical modelling, including simulations of phytoplankton dynamics associated with large-scale offshore marine photovoltaic (MPV) developments.

Statement: Physiological measurements were obtained from controlled laboratory incubations following standardised protocols. After an acclimation period, faecal pellets were collected using a vacuum-based siphoning system and subsequently used to determine sinking velocity in still-water columns by timing their descent over fixed distances. Pellet lengths were measured from microscope images analysed in ImageJ. Respiration rates were derived from changes in dissolved oxygen concentration, which were continuously monitored using calibrated Firesting optical oxygen sensors placed in stirred incubation chambers. Clearance rates were calculated from changes in particle concentration measured with a Coulter counter, and faecal pellet production was quantified from the dry mass and carbon content of pellets collected over known time intervals. All physiological rates were standardised to organism dry weight and carbon content, determined after drying soft tissues. Quality control procedures included calibration of sensors prior to measurements, the use of replicates and procedural controls, verification of calculation procedures, and the dataset underwent standard quality checks before harmonisation and archiving.
