Iodine content in muscles of fresh and marine fish collected from different coastal parts and fresh water resources were analyzed by selective ion electrode method. It was found that fresh fish were rich in iodine content (mean of 23-10 mo g kg^-1 on dry weight basis). Also the iodine content of marine fish, Epinephalus malbaricus (17 mo g kg^-1) and Johnius belangeri (19 mo g kg^-1) on dry weight basis, was higher than that of other marine fish. Significant regional differences were noted in the iodine content of marine fish as compared to fresh water fish.
