摘要: Hydrographic and water quality surveys of the Motueka River its river plume were conducted during a moderate flood event (peak flow 420 m3/s) to assess source fate faecal contaminants transported into Tasman Bay. Escherichia coli (E. coli) enterococci concentrations in up 10000 7300 Most Probable Number (MPN)/100 ml peak flow, respectively. A coastal survey revealed shallow low-salinity that extended at least 6 km Bay region's largest aquaculture management areas (AMAs). Mussels within influence plume, including those collected an AMA, had E. as high 1300 2200 MPN/100 g tissue, Application microbial tracking markers using end-point PCR assays identified presence contamination from ruminant animals (cows, sheep) mussel samples. The detection shellfish located offshore ...
