Current research efforts focus on how the auditory and lateral line systems of fish are used in identifying and localizing biotic (e.g. prey) and abiotic (e.g. rocks) entities in the environment and in general, for forming hydrodynamic images of the environment. Behavioral techniques are used to describe the ability of fish to perform various localization, identification, or discrimination tasks, with and without various sensory systems intact. Neurophysiological techniques are used to measure the responses of cells in the peripheral and central nervous system (CNS) to different stimuli identical to those used in behavioral tasks
