The Effects of Mercury Chloride (Hgcl2) on the Changes in Hematology and Blood Sugar Level in Carps (Cyprinus carpio)

Abstract

One of the increasingly heavy metals concentration is mercury (Hg). Exposure to mercury (Hg) can cause changes to blood hematology of fish caused by accumulation of mercury (Hg) that occurs in various types of organs, especially in the kidneys and liver which can suppress hematopoiesis tissue activity. The purpose of this study is to determine the hematological changes, including erythrocyte, leukocyte, Hb, Hematocrit and blood sugar levels in carps. The method used was an experimental method with Completely Randomized Design (RAL) with 4 treatments and 5 replications at the doses of 0 (control), 0.05, 0.10 and 0.15 ppm. The results show that there is a significant difference in each treatment and parameter. There is a decrease of erythrocytes by 1,678,000 cells/mm3 in treatment D (0.015 ppm), leukocyte increase by 16,360 cells/mm3 in treatment D (0.015 ppm), Hemoglobin decrease by 6.7g/dl in treatment D (0.015 ppm), hematocrit decrease by 10.24% in treatment D (0.015 ppm) and an increase in blood sugar by 99 mg/dl in treatment D (0.015 ppm).
