Acanthogobius flavimanus SYSTEM Freshwater

COMMON NAMES English: spotted goby; Japanese river goby, Oriental goby, yellowfin goby Viet Nam: Cá Bong hoa; Cá Bong

DESCRIPTION flavimanus is easily identified due to its large size. Adult yellowfin goby have a large head and elongate body and can grow to 30cm in length. This is pale brown with a series of dark saddles and spots. Juveniles have pale yellow ventral and anal fins. All ages possess yellow ventral fins whereas other gobies have clear, white, grey or black ventral fins (Barnham, 1998).

NATIVE RANGE ASEAN: ; Viet Nam WORLD: ; ; , Democratic People's Republic Of; Russian Federation

KNOWN INTRODUCED RANGE WORLD: ; United States

PATHWAY Transport - Ship/boat hull fouling

REASON FOR INTRODUCTION It also is hypothesized that introduced gobies arrived as eggs on fouling organisms, such as , growing on ship hulls (Nico and Fuller, 2004).

IMPACTS The introduction of Acanthogobius flavimanus alters fish communities and hastens the decline of native species. In , introductions of A. flavimanus have been associated with extirpations of an endangered species of fish - the tidewater goby (Eucyclogobius newberryi) from certain bodies of water. It also competes with native species for food sources (Meng et al. 1994: Lafferty et al. 1999, Nico and Fuller, 2004).
