Abstract

During the summer of 1956 investigations were made of the movement of fresh-water mussels in the presence and absence of natural food.¹ Classically a sedentary animal, the mussel nevertheless does move about. Marked animals in Lake Okoboji were seen to move up to several meters per day. Obviously, various environmental stimuli could be acting; relatively little work has been reported for this group of animals, nor indeed has the problem of the local movements of animals in general been critically investigated. The rationale of the investigation reported here was simply to compare distance travelled per mussel per unit time in successive weeks in tanks free of food and tanks continually supplied with natural planktonic food.
