The present study was carried out in the Sinop Bay between April 2007 and February 2008 where intensive red mullet (Mullus barbatus) fishing activities were conducted by use of commercial bottom gill nets. For the purpose of the study, dual- core (black and white) two signal system SaveWave ® acoustic devices and 2 pieces of multifilament bottom gill nets, each with a length of 1500 m and mesh size of 17 mm, were used. One of the experimental nets is a non-equipped control net and the other was a net bearing acoustic devices (active net). According to the results of the study, catch per unit effort (CPUE) was 0.96±0.10 kg/km.h with active nets whereas it was 0.50±0.06 kg/km.h with control nets (P<0.05). Moreover, the damage occurred on control nets was 69.8% higher than active nets. On the contrary, the biomass of control nets was determined to be 34.4%. Usage of acoustic devices for commercial fishing was demonstrated to bring a profit of 3.30TL/km.s otherwise each fishing boat to make an average loss of 2191.72 TL throughout the season.
