Estuaries are important habitats for fishes and the understandings of habitat uses of fishes in the estuary can benefit the fishery management and species conservation. Several approaches can be used to study the habitat use of the fish. In this study, we analyze the oxygen isotope compositions (δ18Ootolith) in the [...]
