A sensing unit was composed of a LED (light emitting diode) and a photo-transister. At two sections in the entrance funnel of the pot, one each unit was fixed as a check point. By reading the time lag between transit signals from each gate, the direction of animal locomotion was recognized, furthermore, the number of individuals both entering and escaping animal was counted.}, pages = {20--23}, title = {Detection of Locomotive Behavior in Aquatic Animals by the Use of Infra-red Light}, volume = {13}, year = {} }
