Sound characteristic of Procambarus clarkii

Abstract

Procambarus clarkii is one of the freshwater lobsters which has its own characteristics. Those characteristics used to identify Procambarus clarkii in nature. One of those characteristics is the sound which can be determined using the bioacoustic method. This research uses the bioacoustics method to obtain the sound characteristics from Procambarus clarkii considering this species is invasive in Indonesia. Sound characteristic of this species are obtained by processing sound data into FFT value. The results of processing sound data from recording for three days show that Procambarus clarkii produces snap sound with an average frequency range from 0.3-0.4 kHz.
