The present investigation was under taken to assess toxicity of both Amino-azodyes Congo-red and Chloramine-blue on few vital tissues, (Gill, Foot, Mantle and Hepatopancreas) of Lamellidens marginalis. Test animals were divided into three batches. First batch were exposed to sublethal concentration (80mg/l) of Congo-red and second batch were exposed to sublethal concentration (60mg/l) of Chloramine-blue for acute (48 and 96) and chronic (15 and 30 days) exposure. The third batch were kept in ordinary tap water under idential physiochemical condition serve as control. The change in protein content of Gill, Foot Mantle & Hepatopancreas of test animal was observed at acute and chronic exposure of both Amino-azodyes. Significant (P<0.05) inhibition in protein content was found in Gill, Foot and Mantle while significant (P<0.05) elevation in Hepatopancreas at acute and chronic exposure of Congo-red & Chloramine-blue. The inhibition in protein content may be due to suppressed incorporation of protein synthesis or increased break down of protein into amino acids which diffused out of cell in Gill, Foot, & Mantle. The elevation in protein content may be due to anabolic metabolism in Hepatopancreas.
