  Hydroacoustic method has been used in various field of marine research. Use hydroacoustic method is a method developed to obtain information about the mangrove crab (Scylla sp.). This study analyses the value Target Strength (TS), Power Spectral Density (PSD), and Fast Fourier Transform (FFT) used the instrument hidroakustik. Data collection was performed at the Laboratory of Marine Acoustics using instruments CruzPro PCFF-80 operated with a frequency of 200 kHz. Results of detection of the target by looking at the value of Target strength, strongest TS value can be seen at a depth of 0.6 meters from the transducer with estimations it is the result of target detection. The target strength (TS) of the mangrove crab (Scylla sp.) ranged between –50 and –54 dB. TS value at ping number of 0-500 have a greater value is the value of -55 dB, TS value at that time have in common wi.. Read More»
