Abstract
It is suspected that some of the mangrove near mining areas have a decline in quality due to mining activities. This study aims to determine the damage to hepatopancreas tissue in mud crab Scylla sp caught in the mangrove area in Bombana Regency, Southeast Sulawesi, Indonesia. The number of crab samples examined was 75 individuals with three sampling times with an interval of 1 month from July to September 2019. Histological examination was carried out on the hepatopancreas using the procedure for making histological preparations. The results of histological examination of the hepatopancreas found bacterial colonies, damaged epithelial desquamation, and necrosis. Tissue damages and Hg-absorption are thought to be due to changes in the environment where samples were taken in the mangrove area.
