Abstract
Sound production of male fish-black Tilapia (Oreochromis mossambicus) used bioacoustic method where this method can be analyze behavior and characteristics of the sound production bubbles of tilapia fish swimming in freshwaters with different salinity. Research activities conducted in June 2013, fish were reared in our Institute’s laboratory (Marine Acoustic) as much as 65 males fish-black Tilapia (Oreochromis mossambicus). Sounds were recorded with a High Tech SQ 03 hydrophone (sensitivity -162 dB re 1 VμPa-1 @20°C, frequency response within ± 1 dB from 7 Hz to 22 kHz) placed just above the rim of a territorial in aquaria with connected to sea phone sensor (Dolphin Ear), with recording software is Wavelab 6, and analysis software of Source Level, and Power Spectral Density (PSD) is Matlab R2008 b. Source level (SL) value is highest on first day after adding saline to 39.11 dB, while the lowest values were also in first day after adding salt levels are 38.72 dB, it clearly proves that the addition of salt levels can affect the value of source level (SL). Highest of PSD in after adding salinity first day with -39.03 dB/Hz, and the lowest value of the PSD which in adding to the salt levels in second day is -49.04 dB/Hz. The results shown prove the effect of salinity on the value of the PSD and also SL. Addition of salt levels greatly affect the value of the intensity, frequency, source level (SL), and power spectral density (PSD) of male fish-black Tilapia (Oreochromis mossambicus).
