Abstract
This study aims to determine the content of heavy metals Cu and Zn and histology of Grouper Epinephelus suilus. Survey research methods with technique of data collection on a 3-point sampling station. Data were analyzed descriptively. The results showed an average content of Cu and Zn at estuaries station is 005 mg L. marine station and pond station that was equal to 0.02 mg L and 0.04 mg L. Zn content in estuaries station is 015 mg L pond of 0.1 mg L and marine station of 0.08 mg L. The content of Cu and Zn in the sediment that obtained at each station showed ponds station of 1.45 mg g marine station and the estuaries stationthat is equal to 1.42 mg g and 1.08 mg g. Zn content in ponds station is 6.9 mg gram. While in the estuary of 4.55 mg and 6.5 mg marine station. The content of Cu and Zn in fish in ponds station of 0.46 mg k marine station and the estuaries station that was equal to 0.31 mg kg and 0.35 mg kg. Content of Zn obtained the highest Zn concentrations of metals found in estuariesstation that was 285 mg kg. pond of 2.5 mg kg and marine station in the amount of 1.52 mg kg. Histological damage on gill tissue liver and kidneys found any histological changed that gill hyperplasia and fusion lamela. On liver histology found degeneration edema and some necrosis whereas in the kidneys was found edema and necrosis.
