Plauche* PREFATORY ABSTRACT THE PRESENT STUDY SHOWED THAT AS MUCH AS 69.5 PERCENT OF THE WEIGHT OF THE SOUTHERN OYSTER MAY BE LOST AS FLUID IN THE FIRST 50 MIN- UTES AFTER SHUCKING. TO ACQUIRE BASIC INFORMATION NEEDED IN THE CON- TROL OF SUCH LOSSES, THE AUTHORS INVESTIGATED SEASONAL AND GEOGRAPHIC DIFFERENCES IN THE AMOUNT OF FLUID LOST FROM THE OYSTER AND ALSO STUD- IED RELATIONSHIPS BETWEEN THE CONCENTRATIONS OF PROTEIN, SALT, AND CELLS IN THE BODY FLUIDS. BACKGROUND The loss of body fluid is a problem of great economic concern to the oyster in- dustry. Loss of fluid affects the appearance and the palatability of the oyster and causes serious difficulties related to the fill of container. Investigation of the physiology of body fluid in the oyster Crassostrea virginica, which is the commercial species fovrnd along the East and Gulf coasts, has been in
