Abstract
A field study was conducted to determine mercury accumulation rates by brown shrimp, Penaeus aztecus, transferred to a mercury contaminated estuary, Lavaca Bay, Texas. Mercury levels in the caged shrimp rose fr om an average baseline value of 347 +/- 163 ppb to 1170 +/- 107 ppb in 36 days, resulting in an average rate of mercury uptake of 22 ppb per day. Our results show that shrimp rapidly accumulate Hg when confined to a contaminated area, even though the natural population of shrimp in Lavaca Bay is not contaminated.
