Abstract:Within populations of adult Müller’s pearlside Maurolicus muelleri the otolith radius tended to increase with age at a given fish length, which indicated the presence of a growth-rate effect. Among populations the relative otolith size was negatively correlated to growth-rate estimates, which again indicated a growth-rate effect. There were only minor differences in temperature conditions among the locations, and birth-date differences did not appear to account for variation in otolith radius relative to fish length in older age groups. The presence of a growth-rate effect may be useful, as the relative otolith size may be used for evaluation of age and growth estimates, although there are several limitations to its usefulness.
