| Abstract: | We investigated seasonal dynamics of fish in tidepools on tidal mudflats in the Tama River estuary, Japan. A total of 1,156 individuals of 8 gobiid species were collected from May 2008 to April 2009. The total abundance of fishes peaked in September and October. Of three dominant species, Acanthogobius flavimanus was found only in spring and early summer, whereas Pseudogobius masago and Mugilogobius abei occurred in all seasons. The utilization patterns of tidepools with/without cobbles were different among the latter two species. |
