Abstract

Isolated brown bullhead catfish, Ictalurus nebulosus, were conditioned to discriminate between water samples from aquaria containing solitary conspecifics. Urine and extracts of urophyses, thoracic spinal cord, integument, gill and urinary bladder were then assayed to determine if they were active in effecting this discrimination. Urine and urophyseal extracts were consistently most active as sources of chemical information.
