During the summer and autumn of 1926 frequent visits were made to the oyster beds in the upper Fal Estuary, and in view of the continued decline in the yield of oysters from these grounds, the opportunity was taken to record any facts which, besides being of value in the study of the bionomics of the oyster, might also be helpful in determining those steps most likely to lead towards an improvement of the general state of the fishery. A special investigation of the spawning in relation to tides and temperature was made, and will be compared in a separate publication with similar work carried out at about the same time on the River Blackwater beds in Essex.
