Abstract

The larval phase of most species of coral reef fishes is spent away from the reef in the pelagic environment At the time of settlement these larvae need to locate a reef and recent research indicates that sound emanating from reefs may act as a cue to guide them Here the auditory abilities of settlementstage larvae of four species of coral reef fishes families Pomacentridae Lutjanidae and Serranidae and similarsized individuals of two pelagic species Carangidae were tested using an electrophysiological technique auditory brainstem response ABR Five of the six species heard frequencies in the 100–2000 Hz range whilst one carangid species did not detect frequencies higher than 800 Hz The audiograms of the six species were of similar shape with best hearing at lower frequencies between 100 and 300 Hz Strong withinspecies differences were found in hearing sensitivity both among the coral reef species and among the pelagic species Larvae of the coral reef species had significantly more sensitive hearing than the larvae of the pelagic species The results suggest that settlementstage larval reef fishes may be able to detect reef sounds at distances of a few 100 m If true hearing thresholds are lower than ABR estimates as indicated in some comparisons of ABR and behavioural methods the detection distances would be much largerThis research was supported by ARC Discovery Grant DP0345876 DST International Sciences Linkages Grant IAPISTCG0300442 and I Suthers The authors thank R Piola for laboratory assistance K Poling for technical advice and the staff at Lizard Island Research Station
