Otolith Chemistry as an Indicator of Migratory Behavior

Research Overview

With Prof. Dave Secor of the Center for Environmental Science/Chesapeake Biological Laboratory, detail analysis of the chemical variability of calcitic/aragonitic otoliths are being performed. The variation in chemistry of otoliths has been found, in part, to be due to the migratory behavior of anadramous fish. As part of a feasibility study, stripped bass were reared at a hatchery in waters of varying salinity, and the chemistry of the otoliths related directly to the salinity of the waters in which they were raised.
