Acquisition de donnée en continu sur la matière particulaire de la Baie estuarienne de Marennes-Oléron pendant le bloom printaniter planctonique : effet sur le taux de filtration de l'huître Crassostrea gigas ArchiMer
Heral, Maurice; Razet, Daniel; Prou, Jean.
The continuous obtention of different signals has been achieved for 9 days at a -fixed station during May 1988. The speed and direction of the currents have been monitoring concurrently with "in situ" turbidity and fluorescence in relation with the meteorological conditions. The concentration in particulate matter and the planktonic fluorescence fluctuated in direct relation with the water depth, the speed of the current and with the origin of the water masses. The oysters submitted to these large fluctuated conditions showed not constant filtration rate. The filtration calculated by turbidimeters (2 1 h-l g-1 dry weight) was three time less than the one achieved with fluorimeters (61 h-l g-1 dry weight). The filtration rate were fluctuated but not in...
