As results of an attempt to discriminate an instrumental feeding response with a light stimulus in bluegills, stable discriminated response was established in all 4 experimental fish, even though a maximum of 43 training sessions each of which consisted of 9 trials were required. Regarding the response under presentation of the stimulus after establishment, responding rates in terms of number of responses per min correlated negatively to latencies which were elapsed time from onset of the stimulus until initiation of first responding (r=-0.70 to -0.79: P<0.01). Under presentation of stimulus, the fish started to respond witih latencies of less than 30s on 72 to 88% of total trials, whereas during periods between successive stimulations they did not emit response at all on 60 to 67% trials or, if they did respond, they initiated with it latencies of 60 s or more on 20 to 24% trials. These facts suggest to us that more frequent and faster responding of the fish during the stimulus presentation than during the inter-signal periods was based on relevancy of responding to the light stimulus which functioned as a discriminative one.
