Abstract
Terapon jorbua which is an endogenous species in Indonesia had a serious threat due to water temperature increases as
the impact of global climate change. Conservation as an effort to minimize this impact requires comprehensive information
regarding various aspects of fish, including biacoustic. Passive acoustic method that using hydrophone has had been used
to identify the sound characteristics of three individual fishes (total length 6, 9, and 12 cm) in aquaria at the laboratory
conditions. Individual Terapon jorbua was detected produced sound at frequency in a few kilohertz with a short duration,
and spectral peak above -50 dB. These characteristics are as the initial information in a series of bioacoustic identification
for conservation purposes.
