Figure 1

Migratory history of the giant mottled eel Anguilla marmorata as indicated by the temporal pattern of the Sr:Ca rations in their otoliths. Plots of otolith Sr:Ca ratios along a transect line from the core to the edge of the otolith for all specimens (115) of the giant mottled eel Anguilla marmorata in Indonesia, Japan and Vietnam. The solid line in each panel indicates the marine water life period (≥6.0 × 10−3 in Sr:Ca ratios), and the dotted line in each panel indicates the freshwater life period (<2.0 × 10−3 in Sr:Ca ratios). Numbers on upper right indicate fish number. Error bars indicate standard deviations. FW: freshwater, BW: brackish water, SW: sea water, LBW: lower brackish water, HBW: higher brackish water.
