Sound Diversity as Representation to the Behavior of Spiny Lobster <I>Panulirus homarus</I> (Linnaeus, 1758)

Highlight Research The sound of d spiny lobster (Panulirus homarus) was identified, named rasp; slow rattle; and popping characteristics represent its behavior Passive acoustic visual record method combination implemented to analyze the relation between sounds Abstract Spiny Panulirus homarus is one many important economic fishery resources in Indonesia. Continuous exploitation activities natural habitat can potentially disturb sustainability resources. This species known produce with certain highly dependent on environmental changes. study aimed investigate as a representation behaviour. produced by P. recorded for 24 hours using hydrophone (a passive technique). converts wave lobsters into electric voltage millivolts, then were converted digital number, order be saved virtual format *.wav extension. video system captured data behaviors resting, territoriality, aggression, social attitudes. results showed that emitted rasp, rattle, type sound, characteristics. All types characterized broadband frequency (4 - 20 kHz), source level ranging from 125 145 dB re 1 µPa. Rasp consisting 12 40 pulses duration 100 400 ms, represents defensive behavior. Slow rattle 2 7 did not specific behaviour it dominant during night. However, only pulse represented feeding
