The abilities of threadfin shad ( Dorosoma petenense ) in using chemosenses to detect the scents of conspecifics, a predator and food were tested in the laboratory. Shad did not respond to the scents of conspecifics or a predator; possibly because both shad and their predators out‐swim such cues as chemical scents that are transmitted slowly through the water. Shad showed a strong attraction to the scents of food. In feeding, chemosenses may be used for filter feeding on microscopic food and for locating food beyond the range of vision.
