Oyster Investigation for the Fiscal Year 1949-1950

This investigation is a study of the environmental features which will determine the suitability of areas for production of market oysters. During the past three years emphasis has been placed upon studies of the effects of environment and ecological relationships involved in the transplanting of seed oysters. Five bays, (Aransas, Copano, Mesquite, Carlos, and Redfish) in the vicinity of Rockport have been utilized in the establishment of one acre test plots. This period emphasis has been mainly on a preliminary survey of the spawning and setting activities in the area, including some data on spat size and growth. Data was obtained on oyster quality and a monthly series of the three quality factors has begun at the close of the period. Routine collection of data on hydrography and plankton for correlation with oyster quality and productivity was continued.
