Notes:
On 3 occasions during summer 1977, small groups of a typically run- and pool-dwelling minnow (blacktail shiner, Cyprinella venusta) were observed feeding in a shallow riffle on items dislodged by foraging northern hog suckers (Hypentelium nigricans). Although such nuclear-attendant following behavior has been documented in marine systems and has been reported from some African freshwater lakes, descriptions from freshwater streams are rare. We describe the interaction and consider the probable development of the search behaviour of the blacktail shiners. We also explore the possible benefits of searching for hog suckers in small groups, as observed, rather than as individuals or in large groups. This feeding strategy may be an important mechanism of food acquisition for some individuals when usual resources are scarce.
