Fig. 6. Maps showing the collection of leptocephali of Japanese eels in the Pacific (left) and Euroepan and American eels in the Atlantic (right). Areas where the leptocephali of 10 mm of Atlantic eels were collected indicated as the overlapping shaded oval in the right panel, as shown by McCleave et al. (1987). The areas sampled within one degree squares for the Japanese eel between 1956 and 2002 showed as black dots, and the catches of Japanese eel leptocephali were black circles. The area where leptocephali 10 mm have been collected indicated as the shaded oval in the left panel. The black squares in the right panel showed the locations where leptocephali 7 mm of both species were collected at the same station. The inset shows the locations where larvae 7 mm of the Japanese eel have been collected (the stations inside the box west of the Suruga Seamount larger larvae are also shown in the circles outside of the box) in the left panel. The number of genetically identified specimens at each station is shown in circles in the inset, and the left panel also shows the catch locations of metamorphosing leptocephali (black triangles) and oceanic glass eels (black squares).
