Grouper (Epinephelus fuscoguttatus) produced sound when conducting some activities including feeding. The objective of research was to determine the sound frequency characteristic of E. fuscoguttatus and to investigate known the behavior pattern when the fish detects source of sound. The method of research was experiment laboratories, with research step was known frequency and intensity of sound E. fuscoguttatus when feeding activity, and known behavior pattern E. fuscoguttatus when detecting of source of sound. Acoustic behaviour E. fuscoguttatus when feeding was range from 16-32 Hz (58.9 dB) at average on 100 mm TL and range from 16-128 Hz (55.8 dB) with average on 250 mm. E. fuscoguttatus didn’t had swim bladder and linea lateralis not distinct, caused E. fuscoguttatus didn’t response with source sound (as attractor) in a laboratory scale.
