Abstract: Using 2015 seasons of the North of Yueqing Bay seawater culture areas and Yueqing Bay germ plasm resources environmental quality monitoring results, we analyzed and evaluated the fishery water quality of two areas and sediment quality condition, and compared with the monitoring results made in 2014. The results showed that the the overall water quality of main fishing areas in the city in 2015 could meet the demand of the fishery water quality function, two overall water quality in monitoring areas were consistent with that of last year. The main over standard indexes of affecting the water quality comprehensive evaluation were inorganic nitrogen, active phosphate, petroleum and volatile phenol. The mainly over standard indexes of sediments were heavy metal copper and fecal coliform. Water quality index(WQI) of the north of Yueqing Bay seawater culture zones is medium throughout the year , WQI of Yueqing Bay germ plasm resources is good throughout the year.
