Dataset for Estimated Closures of Scallop (Pecten maximus) Production Areas Due to Phycotoxin Contamination along the French Coasts of the Eastern English Channel

Commercial bans due to harmful algal blooms (HABs), which are natural events, question the sustainability of human activities in marine and coastal areas. A risk assessment these is important support decision-making better manage mitigate their impacts. However, data sparse difficult collect. The dataset presented this paper includes “estimated closures scallop fishing areas” HAB toxicity along French coasts English Channel. closure were simulated for each (Pecten maximus) area through an algorithm applied situ from monitoring network REPHYTOX. methodology production consists comparing phycotoxin concentration regulatory thresholds phycotoxins, then, simulating number duration based on strategies mechanisms as defined regulations. These only cover related threshold exceedances phycotoxins shellfish. Closures induced by lack sampling or other reasons (e.g., failures toxin analysis) not included because information. Data produced during season. Facing non-existence such a database centralized management local decrees, can be used analyse deal with HABs highlight governance challenges strategies. It also useful study link between ecological socioeconomic dimensions HABs, describe how concentrations shellfish translate into impacts challenges. This species, areas economic activities.
