¹It consists of the ID in the study by Chow et al.¹⁶ plus the release location. ²Eye index (= {[(A + B)/4]² × π/TL(mm)} × 100, A; horizontal orbital diameter (mm), B; vertical orbital diameter (mm)). ³Stages were determined from the the colorations of pectoral fins and ventral skin according to Okamura et al.⁶⁶. ⁴Swimbladders of these wild eels were surgically malfunctioned. ⁵They were Y2 stage from a view of body colorations but had eye index ranging in the S1 stage in Okamura et al.⁶⁶. ⁶The eel (WE4263_TS) did not exhibit normal diel vertical migration, so this eel was exclueded from the horizontal swimming analysis.
