Santander, port Espagne, Spain
Main results: - 12 months of successful recording without in-situ human intervention (no diver, no land survey technician) - Data were automatically published daily on the MolluSCAN Eye website showing that the MolluSCAN Eye tool is an easy to communicate in simple words with the public ("be simple") - No acute contamination event was observed ![]() - Nevertheless, in the Port of Santander, the oysters exhibit numerous signs of stress suggesting a negative interaction of the environment. - Oysters were chronically « nervous », not relaxed ( increased number of partial closures) - Oysters were much more often switching from open to close states than in reference sites (Bay of Arcachon, Gulf of Morbihan, Bay of Marennes Oléron: 6 years of reference) - Their biological rhythms were altered (some components were absent) - The growth rate was obviously slow down - However, the why remains to be solved. HFNI valvometry reveals symptoms of physiological impacts and can reveal exact timing: nevertheless often causes remain an open question without supplementary data (note that it is often the same to identify and understand the exact causes in human diseases...) In Conclusion: -The MolluSCAN Eye is a mature tool, ready for professional users. It is an early warning sensor, a tool to chronically measure symptoms of welfare in bivalves but thanks to a data stocking policy, it can also be used for post analysis in accident investigation (as a black box in airplanes). A retrospective analysis of the recorded parameters (stored daily in our laboratory) can participate to the detection and identification of causes or contributing factors.
