Toxicological and Biochemical Alterations of Cypermethrin (Synthetic Pyrethroids) Against Freshwater Teleost Fish Colisa fasciatus at Different Season
نویسندگان
چکیده
The cypermethrin (synthetic pyrethroids) has shows strong piscicidal activity in freshwater teleost fish Colisa fasciatus for all the exposure periods (24h or 96h) in time as well as dose dependent manner. The LC values decreases from 0.009 (24h) to 0.006 (96h) in winter season (water temp. 16°C) and 0.06 (24h) to 50 0.02 (96h) in summer season (water temp. 28°C). Sub-lethal doses (40 and 60% of LC ) of cypermethrin after 96h 50 was also significantly alter the levels of total protein, total free amino acid, in muscle and liver tissues, nucleic acids (DNA and RNA) in gonadal tissues and the activity of enzyme acetylcholinesterase (AChE), lactic dehydrogenase (LDH) and succinic dehydrogenase (SDH) in nervous tissue of the freshwater teleost fish C. fasciatus in time and dose dependent manner.

Biochemical markers are measurable responses to the exposure of an organism to xenobiotics as well as very suitable biosensors of aquatic pollutants. Aquatic pollution can easily be detected through biomarkers, as enzymes provide one of the most reliable means of assessing the degree of exposure of animals to pollutants. Some of the biochemical alteration occurring in the body gives the first i...

In this study, freshwater fish Cyprinus carpio was exposed to sub lethal concentration of synthetic pyrethroids insecticide cypermethrin to evaluate the impact on nucleic acids in different organs. Fishes were exposed to sub lethal concentration (1/10th of LC50 value) of cypermethrin for three different durations, 7, 14 and 21 days. In seven day exposed fishes, DN...

Dysdercus species are important pests of cotton because of their staining effect on cotton lint. Chemical control, using the newer generation of insecticides known as the synthetic pyrethroids, is the most important method of control of these pests on cotton in Kenya at present. Susceptibility studies were conducted using three pyrethroids, namely Cypermethrin, Fenvalerate and permethrin agains...

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. ...
