图 6 各工况下鲢幼鱼上溯轨迹分布图
(a) 单尾鱼在无障碍流场内的上溯运动轨迹分布，(b) 群体组在无障碍流场内的上溯运动轨迹分布，(c) 单尾鱼在局部障碍流场内的上溯运
动轨迹分布，(d) 群体组在局部障碍流场内的上溯运动轨迹分布。数值 0~10 分别代表鱼类分布频次大小，数值越大表示鱼类在该点位出现
次数越多。
Fig. 6 Distribution of ascending trajectories of juvenile H. molitrix under different treatments
(a) ascending movement trajectory distribution of a single fish in the low-turbulence flow field, (b) ascending movement trajectory distribution of ten fish
in the low-turbulence flow field, (c) ascending movement trajectory distribution of a single fish in the locally high-turbulence flow field, (d) ascending
movement trajectory distribution of ten fish in the locally high-turbulence flow field. Numerical values from 0 to 10 represent the frequency of fish distri-
bution, with higher values indicating more frequent occurrences of fish at that location.
