Azo dye and hexavalent chromium are two carcinogenic and toxic pollutants present in industrial wastewater. Zinc oxide nanoparticles can be used for the treatment of these pollutants with solar energy. However the nanoparticles themselves generally have some inherent toxicity for aquatic life. In this work, we have selected Channa punctatus as the model aquatic animal and examined whether the n...

Present study has been undertaken to assess the toxicity of cadmium in vitro for viability of hepatocytes, lactate dehydrogenase leakage, glutathione and lipid peroxidation in Channa punctatus (Bloch), a freshwater snake head fish. Three concentrations of cadmium as cadmium chloride (0.1μg/ml; 3.0μg/ml and 5.0μg/ml) besides one control has been selected. Observations reveal that except lowest c...

The aim of this study was to investigate fungal infections in Channa punctatus and striatus twenty specimens each species were studied for the presence infections. Infected fish’s shows clinical signs such as growth on skin, fins, eyes, eroded fins scales, hemorrhages body surface abdominal distension. ability aquatic fungi cause diseases fish is well known potentially all freshwater fishes the...

Environmental Protection includes programs that are aimed to reducing risks the environment from hazardous materials and chemical wastes. Nowadays, 17α-ethinylestradiol, a synthetic estrogen, has become one of most commonly used active ingredients for oral contraception, interfere with normal functioning endocrine systems, thus affecting reproduction development in wildlife. The fresh water foo...

The purpose of this study was to assess the water qualities and genotoxicity of Maheshara Lake situated near Gorakhpur, India. The lake receives many types of pollutants from two industries, agricultural run-off and domestic sewages. A total of five sampling stations were established for measurement of water pollution and the measurement of cytogenetic alterations in vivo is considered an initi...

In the present study different regions in the scales of Channa punctatus were investigated for elemental composition to see the impact of mercury on them. Five sublethal concentrations of mercury were used after calculating the LC50 value which is 1.21mg/L in 96 hours. When focal and lepidontal regions of scales were seen under electron probe analysis (JEOL 8600M), they were composed of four ma...

The aim of this study was to examine the histological changes in the liver of fish Channa punctatus (Bloch) for a short term (8day) and long term (30 days) exposure in response to the Phenolic Industrial effluents of Bhilai Steel plant. Fishes were exposed in different concentration (low .01%, .015%, .02, .025%) and ( high concentration 10%, 20%, 30%) of Phenolic effluent. Tissu sections of the...

Adult Channa punctatus murrels of both sexes (60-80 g) were collected locally from Ramgarh Lake during the second week of every month (10 individuals of each sex/month) throughout the year. Blood samples were collected and analyzed for serum calcium and phosphate levels by the methods of Trinder (1960) and Fiske and Subbarow (1925), respectively. Gonads were fixed to judge the state of maturati...
