Abstract

This report describes a field experiment which was primarily intended to quantify the beneficial effects of intentionally exposing oysters to air during their growing period. Test samples were submerged in the water at different depths and the normal tidal activity uncovered the samples for differing percentages of the tide cycle. The amount of time each sample was in air was monitored by a specially designed electronic instrument and logged. The logged data was processed into graphical data showing the growth rate of the test subjects with respect to exposure. The occurrence of Polydora was also monitored during periodic inspections and correlated with the amount of air exposure. A secondary objective of the experiment was to evaluate external shell fowling.
