Abstract
Auditory sensitivity of the goldfish (Carassius auratus) have been studied by various workers using different behavioral methods, psychophysical techniques and acoustic conditions. A comparison of the results revealed variations in threshold data up to 80-90 dB. In order to determine the basis of this variation, auditory thresholds were obtained using classical conditioning and the method of limits. The data obtained were compared with those obtained by Popper (1971), who used the same acoustic conditions hut with avoidance conditioning and the method of trackina as behavioral method and psychophysical technique. The two sets of data showed no significant variation indicating that variations in previous data on auditory threshold of goldfish were primarily caused by acoustic conditions in different laboratories .
