The study has been carried out to assess the accumulation of heavy metals in the ichthyofauna of Chippaleru mangroves of south coastal AP, India. The water, sediment and fish tissue were collected at 3 locations. After the collection, the materials were washed with distilled water and they were dried and acid digested. Further the samples were subjected to analysis of heavy metals by flame atomic absorption spectrophotometer. Triplicate samples were analyzed. The levels of heavy metals, in water, were higher during monsoon and same is the case with sediment. The Cd concentrations in the liver of fishes: Mugil cephalus (0.99); Chanos chanos (0.81 and Lates calcarifer (0.11). The Milk fish accumulated more Hg (0.98) in its muscle than other fish.
