Abstract
The environmental dreadful condition in the coastal area of Semarang is caused by an abrasion and mangrove ecosystem damage. Environmental degradation will affect the aquaculture ponds in coastal areas, which can also influence the quality of milkfish (Chanos chanos) reared in ponds. The purpose of this study is to determine Cu concentration in water and sediments on milkfish ponds and also distinguish the pattern of Cu accumulation in fish during their growth period. The samples used in this study were Cu in water, sediment and milkfish collected during 3 months research period. This study was an ecological approach. Data of Cu bioaccumulation in sediment, water and fish were analyzed based on the concentration factor (CF) formula and concentration ratio (CR). Research results show that the Cu content in water was between 0.2-0.3 mg L -1 and in sediment was between 18.09 to 22.81 mg L . According to this result, water Cu content was above the threshold. Based on the rule no. 51 2004 on sea water quality standard by the Ministry of Environment - Indonesia, it states that the threshold of Cu level in marine biota is at 0.008 mg L -1 . The presence of Cu pollution in milkfish needs an attention related to the ability of fish to accumulate metals from the environment. Interestingly, Cu in fish was between 1.165-3.396 mg L -1 ; bellow the threshold permitted by BPOM No. 03725/B/SK/VII/89 1989 amounted to 20 mg L -1 . People must be aware of the presence of this metal in fish since it could be harmful for human’s health.
