CADMIUM TOXICITY INDUCED MORPHOLOGICAL ALTERATION IN INDIGENOUS FISH Heteropneustes fossilis (Bloch.)

Microcystin toxicity in a freshwater fish, Heteropneustes fossilis (Bloch)

Microcystin is a toxin secreted by cyanobacteria, which are the dominant phytoplankton in eutrophic freshwater bodies. The present study reports histopathological, hematological and biochemical changes in the freshwater fish, Heteropneustes fossilis due to toxicity of microcystin. Toxic effects were observed in liver, kidney, corpuscles of Stannius, gills and gonads. Bilirubin concentration inc...

Histological Studies on Kidney of Cadmium Chloride Exposed Freshwater Catfish , Heteropneustes Fossilis ( Bloch )

Effect of Cd++ On Catalase Activity on Air Breathing Fresh Water Teleost Fish Heteropneustes fossilis (Bloch)

The objective of this study is to determine the effect of Cadmium (a heavy metal) on Catalase activity on tissues of liver, kidney and gill of freshwater air breathing Teleost fish (Heteropneustes fossilis). Catalase, a oxido-reductase enzyme play an important role in anti-oxidant defence System which protect animal from oxidative stress. Heteropneustes fossilis (Bloch), a medicinally important...

Acute toxicity bioassay of dimethoate on freshwater airbreathing catfish, Heteropneustes fossilis (Bloch).

Pesticides are chemicals used for pest control in the agricultural fields. They finally reach the surrounding water bodies through surface runoff affecting the aquatic fauna. Dimethoate is frequently used organophosphate pesticide due to its high effectiveness and rapid breakdown into environmentally safe products. A 96 hr static acute toxicity test was carried out to determine the LC50 value o...

Determination of LC50 of cadmium chloride in Heteropneustes fossilis

The fish consumption has been increasing throughout the world with improved awareness among consumers and culture of fish; an important source of proteinaceous foods for human has become popular during the last few decades in entire Indian subcontinent (Kumar, 2007; Prasad and Kumar, 2007; Saxsena and Garg, 2010). In recent past there has been reports of poor quality fish with high metal conten...
