The fish host, Acanthogobius hasta, was sampled monthly (April 1990 to March 1991) from Wando Islands, Korea, and examined for the parasitic Copepod Acanthochondria brevicorpa. Prevalence was positively correlated with fish length; parasitic copepods were only found in fishes > 24 cm TL. distinct seasonal variation in prevalence and intensity of A. brevicorpa infection was observed, although no data were available in April, June and July 1990 when no A. hasta was caught. Averaged over all samples, of the 83 fishes caught, 34.9% were infected with a mean intensity of 3 copepods per host No A. brevicorpa was found on the host between August and October. Ovigerous females of the Copepod were found between February and May, with an abundance peak in May. Young copepodids (Ci to CIII) of A. brevicorpa were not present throughout the year, but only late copepodids of CIV and CV were found on the fish in March and May. Results from the present study suggest that A. brevicorpa mainly produces larvae in spring, and may have a life cycle including additional hosts.
