However, an integrated mechanistic risk model framework to predict the impact of Hg(II)/MeHg on freshwater fish is lacking. Waterborne and dietborne exposures of freshwater fish to mercury (Hg) in the forms of inorganic (Hg(II)) and organic (methylmercury or MeHg) affect their growth, development, and reproduction. Subsequently a cross-sectional survey for the prevalence and diversity of FZT in tilapia culture systems was conducted in Guangdong.Īssessing exposure risks for freshwater tilapia species posed by mercury and methylmercury.Ĭheng, Yi-Hsien Lin, Yi-Jun You, Shu-Han Yang, Ying-Fei How, Chun Ming Tseng, Yi-Ting Chen, Wei-Yu Liao, Chung-Min pumilio along with some unknown species whose identifications are still being determined. The wild-caught fish species included Hemiculter leucisculus (145), Rhodeus sinensis Gunther (10), Rasborinus lineatus (96), Squaliobarbus curriculus (6.), and Carassius auratus (4).The FZT species recovered were mainly Haplorchis taichui, and H. the potential for FZT transmission in an area with high density of tilapia farms, wild-caught fish from local rivers and canals were bought at local markets. Guangdong Province is the most important region for tilapia (Oreochromis niloticus) culture in China, but it is also an endemic region for FZT. The fishborne zoonotic trematode parasites (FZT) which cause liver and intestinal infections in humans are widespread in fish in Southeast Asia.
