Study of the Oyster Population in the Galveston Bay Area - Survey of Oyster Populations and Associated Organisms

The sample abundance of oyster (Crassostrea virginica) spat decreased in 1963 as compared to 1962, and a further decline occurred in 1964. Seed oysters also declined in sample abundance during 1963 as a result of poor survival among the 1963 (and possibly 1962) oyster spat sets. The seed stock increased slightly during the fall 1964, indicating better survival of the 1964 oyster spat set. Market oysters were abundant in the samples during 1963 but decreased considerably in 1964.
