A fundamental experiment was carried out to confirm the behaviour of Bastard halibut Paralichthys olivaceus to audible underwater sound in a breeding ground around the coast of Cheju Island. To find characteristics of breeding water tank and experiment water tank. ambient noise, undcrwater noise and feeding sound of fish were measured and analyzied respectively.
The results of measurement are as follows:
1. The maximum sound pressure level of ambient noise in breeding water tank was 81dB. average maximum sound level of underwater noise was 81dB at 120Hz.
2. The maximum sound pressure level of ambient noise in experiment water tank was 76dB and underwater noise was 84.2dB at 130Hz.
3. The maximum sound pressure level of feeding sound was 85dB at 120Hz.
