Abstract
In this paper, the validity of the numerical model of fishes' behavior presented in our earlier paper was examined by the whiteness test on the residual of numerical model and by the comparison between experiment and simulation on several indexes represented by fishes' swimming characteristics. The validity of the numerical model was proved statistically by means of the whiteness test of the residual. The similarity was confirmed by comparison between experiment and simulation for the swimming trajectory of fishes, the mean distance of individual from wall, the mean swimming speed and the mean distance between the nearest individuals. These results suggest that the behavior of fishes according to the flow speed in three-dimensional space can be estimated partially by the numerical model presented in our earlier paper. However, a long-term approach to improve the modeling technique on the behavior of fishes may be needed before applying the numerical model presented in our earlier paper to real fishing ground.
이 연구에서는 전보에서 어군의 유영공간을 3차원으로 고려하여 제안한 어군행동을 나타내는 수치 모델의 타당성을 검토하기 위하여 수치 모델의 잔차에 대한 백색성검정 및 실험과 시뮬레이션에 의한 결과를 비교하는 두 가지 방법을 사용하였다. 모형 그물이 없는 경우와 모형 그물이 있는 경우 모두 잔치의 평균이 0에 가까우며, 그 표준편차는 대체로
