Bioaccumulation of Copper (Cu) and Chromium (Cr) on export comodity vanamei shrimp from Karawang, West Java

Karawang is one of regencies in West Java which has great potential for vannamei culture. The farm here was modern farm and using Citarum River as water source. Human activities like household and industry around the river cause its quality decrease and give negative impact to shrimp farm. This research was aimed to investigate the bioaccumulation of copper (Cu) and chromium (Cr) on vannamei shrimp from Karawang, West Java. Amount of shrimp's meat and carapace were used for heavy metal measurement using Atomic Absorption Specthrophotometry. Result showed that contents of copper both in meat and carapace were higher than content of chromium. Moreover, the content of both metals was higher on carapace compared to meat. Since the content of meat were below threshold, so it is safe for consumption. There is no significant difference content of both metals in carapace.
