引進黃鰭刺鰕虎魚(Acanthogobius flavimanus)後，會改變魚類群落結構，加速本地物種族群下降。在加州，黃鰭刺鰕虎魚的引入，一般認為與一個瀕危魚類 - 潮水蝦虎(Eucyclogobius newberryi) 的滅絕有關。它也會和本地物種競爭食物來源(Meng等人, 1994; Lafferty 等人, 1999; Nico and Fuller, 2004)。
San Francisco Bay (Estuary) (United States (USA))
降低本地生物多樣性: Meng et al (1994) suggested that environmental disturbances, coupled with the introduction of this and other foreign species, are altering fish communities and hastening declines of native fishes in California. Although Meng et al (1994) found that the yellowfin goby has an impact on the introduced chameleon goby Tridentiger trigonocephalus, recent investigations have shown this species is actually the shimofuri goby Tridentiger bifasciatus (not the chameleon goby) that occurs in Suisun Bay where the study was conducted (Fleming, personal communication). Hence, it is the shimofuri goby that is affected (Nico and Fuller, 2004).
California (United States (USA))
威脅瀕危物種: The tidewater goby (please see Eucyclogobius newberryi ), an endangered species in the United States, occurs in a series of isolated coastal wetlands in California. Habitat degradation and introduced predators have led to extirpations. Tidewater gobies usually occur in habitats where large piscivorous fishes are rare or absent. Several extirpations of tidewater gobies in the San Francisco Bay area followed the invasion of rainwater killifish and A. flavimanus (Lafferty et al 1999).
“There also is concern that the yellowfin goby might outcompete and possibly eliminate freshwater populations of the small and endangered tidewater goby (Eucyclogobius newberryi) (Moyle 1976a, Nico and Fuller, 2004).
降低本地生物多樣性: Yellowfin gobies have been reported to have partially replaced Pacific staghorn sculpins Leptocottus armatus (Brittan et al 1970) (Nico and Fuller, 2004).
