| Summary: | Because of the frequent conjectures among oyster biologists and others (including the writer) that transfer of oysters from high salt areas to low salinities would probably produce considerable losses, and the commonly expressed opinion that the usual spring freshets in the Barataria Bay watershed were sufficient to produce serious mortality toward the upper limit of oyster culture operations, it was decided to make definite controlled checks to determine whether these opinions were soundly based. The "mortality" racks at Chene Fleur Station were designed to measure the effects of continuous maintenance of oysters in a low salinity area, and this phase will be reported later. This report is concerned with two studies on the effect of transfer of oysters from lower Barataria Bay, where salinities are generally considered to be in the "high" classification, to a station in Wilkinson Bayou, at its junction with Bay Chene Fleur, which is the Bay Chene Fleur experimental station. This latter area is above Barataria Bay proper and is characterized by low winter and spring salinities.
