Size-dependent changes in habitat use of Japanese eel Anguilla japonica during the river life stage

Japanese eel ( Anguilla japonica ) is a commercially important species; however, its population has declined in recent years. Appropriate conservation management, including habitat protection, is required to reverse this decline. However, their habitat use pattern during the riverine life stage is p...

Zusammenfassung:	Japanese eel ( Anguilla japonica ) is a commercially important species; however, its population has declined in recent years. Appropriate conservation management, including habitat protection, is required to reverse this decline. However, their habitat use pattern during the riverine life stage is poorly understood. In this study, we investigated the longitudinal distribution and microhabitat of small-sized (
