GILL HISTOPATHOLOGICAL ANALYSIS OF TILAPIA IN WANGI RIVER WATERS
Abstract
Wangi River has complex waters as they are affected by industrial waste and human activities. The river is in the Beji sub-district, Pasuruan Regency, East Java. The water quality in several urban rivers has deteriorated due to heavy metal pollution. Fish, as one of the river's biota, is also directly affected. Histopathological changes can help identify the pollution severity. This study aimed to examine the histopathology of tilapia gills exposed to Hg, Pb, Cd metals in the Fragrant River's waters. The results found hyperplasia, hemorrhage, and edema in tilapia from 2 stations.
