- F I G U R E 2 Conceptual diagram showing the possible mechanisms driving habitat segregation between the Japanese eel Anguilla japonica and the Indo-Pacific eel A. marmorata in rivers where they coexist. As leaf detritus is more likely to accumulate in more lentic habitats such as estuaries and backwaters, A. japonica glass eels may be attracted to such lentic habitats by odors associated with the detritus. Moreover, such odors may attract A. japonica glass eels more strongly at higher salinities, thus trapping A. japonica glass eels in higher-salinity habitats such as estuaries. Conversely, A. marmorata glass eels are less influenced by these odors when selecting their habitats. However, A. marmorata glass eels are exclusively excluded from estuaries due to their higher mortality in saline water than in freshwater. These processes may explain the habitat segregation pattern of the two species during the later elver to yellow eel stages.
