Two Asiatic Gobiid Fishes, Tridentiger trigonocephalus and Acanthogobius flavimanus, in Southern California

Abstract

While SCUBA diving in Los Angeles Harbor I collected mature adults and eggs of one Asiatic goby, Tridentiger trigonocephalus (Gill) and photographed another, Acanthogobius flavimanus (Temminck and Schlegel). Subsequent collections indicated that both are established in Los Angeles-Long Beach Harbors and vicinity, and that the latter species may be rapidly extending its range in southern California.
