The Physiology, Behavior, and Ecology of Fish Navigation Part 1

Fishes have evolved a diversity of mechanisms by which they extract information about their environment to orient their movements. In the past several years significant progress has been made in identifying sensory cues used by fishes in an ecological context (e.g., the use of sound by juvenile fish to locate patches of reef, the use of magnetic field as a ‘map’ by salmon during their ocean migration, and the use of polarized light for maintaining a compass heading by reef fish). However, how fishes weight this diversity of sensory input during different phases of movement (e.g., dispersal, foraging, homing) and within different environments is poorly known. This symposium will bring together researchers studying the sensory basis of orientation and navigation in fish from physiological, behavioral, and ecological perspectives. All of the major sensory modalities for orientation will be represented (vision, hearing, chemoreception, mechanoreception, electroreception, and magnetoreception).
