We studied the sex ratio of a population of common musk turtles (Sternotherus odoratus) from Dewart Lake in north-central Indiana. From 1979 to 2000 we trapped S. odoratus nearly annually using wire traps or fyke nets. Sex ratios were consistently male biased (average = 64.9% males) and did not vary between trap types or time of day. Available evidence points to differential mortality of the sexes as a possible cause for the biased sex ratios. However, additional work is needed.
