dc.description.abstract The recent decline in Manila clam landings in Korean waters is, in part, linked to a high level of infection by the protozoan parasite Perkinsus olseni. In this study, we first surveyed the infection status of protozoan parasite P. olseni in the juvenile and small Manila clams using Ray's fluid thioglycollate medium assay (RFTM). A total of 578 clams of shell length (SL) ranging 9.2 to 29mm were collected from 9 tidal flats in Gyeonggi Bay, the coast of Taean, Garorim Bay, and Gomso Bay in January and November 2008 and March 2010. The smallest clam (SL 9.2mm) of the survey was originated from Sungam in November 2008, which was infected by P. olseni with the infection intensity of 570, 000 cells/g tissue. RFTM revealed that the juveniles (10-15 mm SL) in Gomso Bay are infected by P. olseni with a mean infection intensity of 491,000 cells/g tissue, suggested that P. olseni infection in the juveniles can be initiated as early as a few months after the settlement. The juvenile (SL 20-25 mm) and small clams (SL 25-30 mm) in Hwangdo Island were heavily infected by P. olseni, with the mean infection intensity of 1.751 x 106 and 4.830 x 106 cells/g tissue, respectively. The survey confirmed that most of the juveniles and small clams in major clam beds on the west coast were infected by P. olseni, and it is believed that P. olseni infection is not limited to the adult clams. -
