Mercury transfer from river sediments to freshwater fish ( Lebistes reticulata ) (wet weight, 29 to 869 mg) was observed for 150 days. Release rate from the sediment indicates a half‐life of 12 to 20 years. The amount taken up by the fish varied widely (up to 600% differences), but half‐lives for clearance were all between 38 and 75 days. No correlation was found between mercury uptake rate and either size or sex of fish.
