Abstract
To examine the role of the lateral-line canal in schooling, the canals of the red sea bream Pagrus major (mean body length, 16.7cm) and the bluegill Lepomis macrochirus (7.8cm) were denervated by cutting the main trunk ramus of the posterior lateral line nerve, mandibular, superficial opthalmic and buccal rami of the anterior lateral line nerve without removing the eyes. Schools of 20 individuals were videotaped over 2 hours while cruising in a tank and mean distances to the nearest neighbor (NNDs) were obtained. In both species, the fish with the denervated canals swimmed slowly in a school but the effect of the sensory denervation on schooling was evident; their NNDs were significantly larger than those of the control. It was hypothesized that the canals on the head were different from the trunk canal in their role in schooling.
