초록

본 연구에서는 음향 산란모델을 이용하여 도루묵의TS를 평가하기 위한 중요한 변수인 음속비와 밀도비, 유영자세각을 측정하였다. 도루묵의 밀도비와 음속비는각각 부피체적법과 음속 도달 시간차법(time-of-fight)으로 측정하였다. 또한, 도루묵의 유영자세각은 주간과 야간 평상시, 주간과 야간 섭이시로 구분하여 계측하였다. 도루묵의 밀도비는 1.001~1.067으로 평균(±표준편차) 은 1.032 (± 0.017), 음속비는 1.007~1.022으로 평균(±표준편차)은 1.015 (± 0.003)이었다. 도루묵의 유영자세각(평균±표준편차)은 주간 평상시 16.8±10.3°, 야간 평상시 1.9±12.3°, 주간 섭이시 30.2±12.6°, 야간 섭이시35.0±13.2° 이었다. 주간과 야간시기 동안 섭이시는 평상시보다 평균 유영자세각이 더 높았다. 이 연구의 결과는 음향 모델을 이용하여 도루묵의 TS를 계산하는 파라미터로 제공될 수 있는 것으로 판단된다.

Abstract

Density and sound speed contrasts (g and h, respectively), and swimming angle were measured for sandfish (Arctoscopus japonicus) without swimbladder. The density contrast was measured by the volume displacement method while the sound speed contrast was measured by the acoustic measurements of travel time (time-of-flight method). The swimming angle was measured by dividing it into daytime, nighttime, daytime feeding and nighttime feeding. The g was 1.001 to 1.067 with an average (± standard deviation) of 1.032 (± 0.017), and the h was 1.007 to 1.022 with an average (± standard deviation) of 1.015 (± 0.003). The swimming angles (mean ± standard deviation) were 16.8 ± 10.3° during the daytime, 1.9 ± 12.3° during the nighttime, 30.2 ± 12.6° in the daytime feeding and 35.0 ± 13.2° in the nighttime feeding. These results will provide important parameters input to calculate theoretical scattering models for estimating the acoustic target strength of sandfish.
