RESPONSE OF HAEMOCYTES COUNT AGAINST HEAVY METAL MERCURY IN WHITE LEG SHRIMP Litopenaeus vannamei (Boone, 1931) | UTTAR PRADESH JOURNAL OF ZOOLOGY
Heavy metal has been identified as a severe environmental hazard, according to numerous studies, due to its persistence and potential to accumulate in organisms and promote food chain amplification. When compared to terrestrial organisms, heavy metal may cause greater problems in aquatic organisms. As a result, the current study was aimed to investigate the haemocyte count in white leg shrimp Litopenaeus vannamei exposed to various sub-lethal concentrations of the heavy metal mercury (10 percent and 30 percent ). The results revealed that hyalinocyte counts (F=32.704; df=2; p0.001) were inversely related to mercury content and exposure time (10, 20 and 30 days). Granulocytes (F=171.009; df=2; p0.001) and semigranulocytes (F=15.221; df=2; p0.001) increased with increasing heavy metal concentration and decreased with increasing exposure duration. It could be attributed to the struggle against heavy metal stress, and it could be accommodated during heavy metal exposure time extension. To determine the amount of toxicity in the target organism, various toxicity studies are usually used. The current study found that haemocyte count is a good indication of heavy metal mercury toxicity. Please see the link :- http://mbimph.com/index.php/UPJOZ/article/view/2487
