Transmission electron microscopic study of gills of freshwater fish Channa punctatus (Bloch) exposed to the toxicity of cypermethrin
In the present study, an attempt has been made to examine the toxic effect of cypermethrin, a synthetic pyrethroid exposed to freshwater fish Channa punctatus. The fishes were exposed to sublethal concentration of 0.08 mg/L for 15, 30 and 45 days. The gills of the fish plays vital role in respiration and are an important organ with specific functions which are highly sensitive to many factors. ...

متن کاملBiomarkers of monocrotophos in a freshwater fish Channa punctatus (Bloch).
Activity of a few biomarkers have been investigated on freshwater fish Channa punctatus treated with monocrotophos for acute exposure to 18.56 ppm at 96 hr and subacute exposure viz. 0.46 ppm, 0.96 ppm and 1.86 ppm for 30 days. Biomarkers such as total protein, lipid peroxidation and acetylcholinesterase have been measured in different tissues of fish viz. gills, liver, brain and muscles. The p...
متن کاملtwo new species of the genus pallisentis van cleave, 1928 (acanthocephala: quadrigyridae) from the intestine of channa punctatus (bloch, 1793) from the river gomti at lucknow, india.
background: acanthocephalans are fish parasites of worldwide distribu-tion, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. no diagnostic tool is available except postmortem inves-tigations and identification by parasitologists. the aim of present study was to explore and assign taxonomical status to pallisentis species prevalent in food fishes of river g...
متن کاملStudies on histopathological changes in the gill, liver and kidney of Channa punctatus (Bloch) exposed to Alachlor.
Freshwater fish, Channa punctatus was exposed to sublethal concentration of a chloroacetanilide herbicide alachlor technical grade and lasso 50% EC for a period of 10 days. The histopathological changes in the gill include: necrosis, vacuolar degeneration, fusion and atrophy of primary and secondary gill lamellae. The tissue damages like degeneration of cytoplasm in hepatocytes, atrophy formati...
