Abstract
- To investigate the possibility of acoustic conditioning for the black sea bream, an experiment on the acoustic conditioning were conducted in marine ranching area. We used developed acoustic conditioning remote system, which consists of sinusoidal wave, feeding device, side-oriented echo sounder, and underwater camera. The radiated signal for acoustic conditioning was driven from an underwater speaker with carrier frequency of 300 Hz and source level of 135 dB. After radiating the signal for the fish, commercial dry pellets were supplied to the fish. A response of the fish to the system was monitored using echo sounder and underwater camera. About 30,000 black sea breams were taken from an artificial breeding ground and kept in a net cage for the experiment. The acoustic conditioning experiment carried out three times in a day and wholly continued during three weeks. As an additional experiment, a series of studies on the acoustic conditioning of the fish were tried to know apparently acoustic response of the fish with transformed water drop sound with mating sound of croakers. In this pilot experiment, the use of an acoustic feeding system installed in a marine ranching area showed a reasonable response of the fish to the system
