Low oxygen events have been suggested as causative factors for the reductio
n of the eastern oyster, Crassostrea virginica in Bon Secour Bay, Alabama.
Because younger C. virginica may be less resistant to low oxygen levels whi
ch more often occur near the substrate, the height above the substrate may
play an important role in their survival. To investigate the effect of low
oxygen on the growth and mortality of C. virginica, a series of multiprobe
data loggers were deployed in conjunction with C. virginica beds at differe
nt heights above the substrate. A simple and inexpensive method for deployi
ng multiprobe data loggers at a defined height above the substrate in shall
ow bodies of water is discussed. (C) 2000 Elsevier Science B.V. Al rights r
