Abstract

Feeding behavior of mussels ( Mytilus edulis) was measured in situ using a video camera and expressed as the mean percentage of valve gape aperture ( VA), concomitant with environmental and biological parameters over two tidal cycles. Mussel feeding behavior and the physical parameters responded to three primary tidal components, of which semidiurnal was dominant ( 12.42 h). VA was synchronized with chlorophyll a ( Chl a) concentration ( proxy for food) with a strong positive correlation ( r = 0.72, p
