Alterations in nitrogen metabolism in freshwater fishes, Channa punctatus and Clarias batrachus, exposed to a commercial-grade λ-cyhalothrin, REEVA-5

Lambda cyhalothrin induced alterations in Clarias batrachus.

The present study was undertaken to find out the toxic effect of synthetic pyrethroid lambda cyhalothrin on the functioning of endocrine glands in freshwater catfish, Clarias batrachus. The fish were exposed to the pesticide for a period of 45 days at a sublethal concentration of 5.768 ppm. Analysis of hormone profile was carried out on the 15, 30 and 45 days of exposure to find out the alterat...

Role of Arsenic on the Regulation of Glycogen Metabolism in Liver of Taki Fishes (Channa Punctatus) Exposed to Cold

Liver is the major organ involved in the regulation of metabolic functions. Environmental and chemical effects are the stimuli regulating metaboilc activities. To clarify the regulation of glycogen metabolism in liver, Channa Punctatus varieties of fishes were exposed to low temperature (4~8C) since these species of fishes are highly energetic and survive in the critical situations. In response...

Haematological Alterations in the Fish Channa Punctatus upon Exposure to Quinalphos Technical Grade and 25% Ec

Renal architectural alterations in Channa punctatus when chronically exposed to mercuric chloride

In the present investigation live specimens of Channa punctatus were collected, after acclimatization they were chronically exposed to sublethal concentrations of mercuric chloride for 15 and 30 days. As compared to the control fish, Mercury treated fish kidney showed marked histopathological changes. After 15 days the alterations detected initially were the widening of space between the capsul...
