Validating a Novel Technique for Evaluating the Feeding Physiology and Behavior of Oyster Larvae
A new tool was recently developed using two colors of 2 µm fluorescent beads to measure ingestion rates, gut volume, and gut passage time in bivalve larvae, specifically Crassostrea gigas (Pacific oysters). In this study, several assumptions were tested that formed the basis of the method: larvae do...
