The yellowfin goby, Acanthogobius flavimanus is native to Asia. It has been introduced to Australia and the west coast of North America through ship ballast water and hull fouling. It negatively interacts with native and endangered species competing for food and resources.
Species Description
Acanthogobius flavimanus is easily identified due to its largesize. Adult yellowfin goby have a large head and elongate body and can grow to 30cm in length. This fish 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).
Lifecycle Stages
Acanthogobius flavimanus larvae are pelagic. Newly hatched larvae swim out of the burrow and remain near the bottom. After the yolk sac is absorbed, the larvae disperse rapidly. Larvae float on the surface of the water column during flood tide and descend to near the bottom while the tide ebbs. Pelvic fins fuse into a sucking disc, and the fish are able to cling to substrates or crawl into burrows. Juvenile A. flavimanus prefer tidal sloughs with a muddy bottom and peatmoss banks (Wang 1986).
Habitat Description
Acanthogobius flavimanus inhabit muddy and sandy bottoms along the shore of bays and estuaries, and sometimes ascends rivers (FishBase, 2005). A. flavimanus are usually found in freshwater reaches of streams just above tidal influence during most of the year. Individual fish are commonly found in bays and inlets in water depths between 1 and 14 metres (Barnham, 1998).
Acanthogobius flavimanus is oviparous, spawning in winter to early spring. During the breeding season in winter months, adults migrate downstream to spawn in the estuaries. Eggs are constructed in intertidal mudflats and deposited in Y-shaped covered nests (burrows or tunnels) 15-35cm deep and are ovoid in shape. Eggs measure 5.5mm long and 0.9mm wide and take 28 days to develop at optimum temperature (13C). The female may leave the burrow after spawning or may join the male in guarding the eggs. The incubation period is approximately 28 days at 13 C. (Barnham, 1998; FishBase, 2005; and Wang, 1986).
Acanthogobius flavimanus have been reported as aggressively feeding on smaller fish (Barnham, 1998). Wang (1986) reports that, \"Major food items for small juvenile yellowfin goby are harpacticoid copepods (Miyazaki 1940) and other copepods (Dotsu and Mito 1955); the large juveniles eat amphipods, mysid shrimp, and small fish.\"
It also is hypothesized that introduced gobies arrived as eggs on fouling organisms, such as oysters, growing on ship hulls (Nico and Fuller, 2004).

General Impacts
The introduction of Acanthogobius flavimanus alters fish communities and hastens the decline of native species. In California introductions of A. flavimanus have been associated with extirpations of an endangered species of fish - the tidewater goby (Eucyclogobius newberryi)\r\nfrom 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).

Summary: In 1993, Canada, Mexico and the United States signed the North American Agreement on Environmental Cooperation (NAAEC) as a side agreement to the North American Free Trade Agreement (NAFTA). The NAAEC established the Commission for Environmental Cooperation (CEC) to help the Parties ensure that improved economic efficiency occurred simultaneously with trinational environmental cooperation. The NAAEC highlighted biodiversity as a key area for trinational cooperation. In 2001, the CEC adopted a resolution (Council Resolution 01-03), which created the Biodiversity Conservation Working Group (BCWG), a working group of high-level policy makers from Canada, Mexico and the United States. In 2003, the BCWG produced the �Strategic Plan for North American Cooperation in the Conservation of Biodiversity.� This strategy identified responding to threats, such as invasive species, as a priority action area. In 2004, the BCWG, recognizing the importance of prevention in addressing invasive species, agreed to work together to develop the draft CEC Risk Assessment Guidelines for Aquatic Alien Invasive Species (hereafter referred to as the Guidelines). These Guidelines will serve as a tool to North American resource managers who are evaluating whether or not to introduce a non-native species into a new ecosystem. Through this collaborative process, the BCWG has begun to implement its strategy as well as address an important trade and environment issue. With increased trade comes an increase in the potential for economic growth as well as biological invasion, by working to minimize the potential adverse impacts from trade, the CEC Parties are working to maximize the gains from trade while minimizing the environmental costs.
