中文摘要	To improve the use of the Chinese loach, Misgurnus anguillicaudatus, as a sentinel species for environmental investigations, normal ranges of plasma vitellogenin (Vtg) was studied. Male and female loaches were collected every 2 months from November 2004 to September 2005, and a specific and sensitive competitive enzyme-linked immunosorbent assay (ELISA) was used to determine plasma Vtg levels. Our data indicated that the average maximum Vtg level of female loaches (757 +/- 356 A mu g mL(-1)) appeared in March, approximately 1 month before spawning. Female plasma Vtg significantly correlated with gonadosomatic index (GSI) which indicated that female plasma Vtg can be used as an indicator of the reproductive stages of the ovary. Low detectable plasma Vtg levels was detected in a number of male loaches, and the highest average plasma Vtg concentration attained to the level of A mu g mL(-1); after exposure to estrogenic compounds by waterborne, injection or oral food, Vtg can be induced in male fish, so the presence of Vtg in male loaches might be attributed to the ingestion of estrogenic substances in food, the contamination of estrogenic compounds from the living environment, or the estrogen used by the local fish breeders to accelerate the rate of growth during artificial culture. The results indicate that Vtg levels in male and female Chinese loaches will be very helpful in field studies which use Chinese loach as a sentinel species.
