Growth rate (length, width, thickness, weight) of individual oysters was determined for three year classes over two growing seasons. In general the largest oysters in each year class continued to be the fastest growing, and length, width and weight were found to be highly correlated with each other. These results are discussed in terms of the following questions concerning a breeding program for faster growing oysters. (1) What trait(s) should be selected? (2) When should selection be made? (3) What effect does selection for one trait have on other traits? Simultaneously, estimates of genetic variability (heritability) have been made. The answers to the above questions plus estimates of genetic variability are necessary in order to make decisions on the best breeding methods for oysters.1 This work was supported by a grant from the National Research Council of Canada. 2 The authors are indebted to the Canada Fisheries and Marine Services Biological Station at Ellerslie, P.E.I. for providing all material and lab space used in conducting this work.
