Acanthogobius flavimanus Acanthogobius flavimanus occurs naturally in Japan, Korea, and China (Fow- ler, 1961; Tomiyama, 1936) in marine, brackish, and river waters (Okada, 1955). It has been introduced into Sydney Harbor, Australia (Hoese, 1973; Friese, 1973). This goby was first found in California in 1963 in the San Joaquin River and the Stockton Deepwater Channel (Brittan et al., 1963). Since then it has been reported from the Sacramento Delta, the San Francisco Bay area, and Bolinas Lagoon (Brittan et al., 1970), Elkhorn Slough (Kukowski, 1972), and Tomales Bay and Estero Americano (Miller and Lea, 1976). It has not heretofore been reported from southern California. An underwater photograph (Fig. 2) taken in Los Angeles Harbor under Pier 228 on 22 September 1977, revealed the presence of A. flavimanus in the rocky "; No specimens were captured. On 29 March 1978, biologists from Ma- rine Biological Consultants, Inc., Costa Mesa, California, took a 156 mm SL male (Fig. 3) in a gill net {W2 in. bar mesh) at a depth of 18 m in the back harbor, Channel 3, of Long Beach Harbor (John L. Wintersteen, pers. comm.). This specimen is deposited in the Natural History Museum of Los Angeles County (LACM 37346-1). The testes of this individual were not well developed. Stomach.
