متن کاملa comparative study on the acute toxicity bioassay of dimethoate and lambda-cyhalothrin and effects on thyroid hormones of freshwater teleost fish labeo rohita (hamilton)
dimethoate (organophosphate insecticide) and lambda-cyhalothrin (synthetic pyrithroid) aretwo frequently used pesticides due to their high effectiveness and rapid breakdown into environmentally safeproducts. the aim of this present study was to assess and compare the acute toxicity of dimethoate(rogor30%ec) and lambda-cyhalothrin (5%ec) on labeo rohita (hamilton). acute toxicity bioassay wascar...
متن کاملA Study on the Toxicity of Chromium on the Histology of Gill and Liver of Freshwater Fish Labeo Rohita
The toxic effect of chromium on the histology of gill and liver of Labeo rohita fingerlings was studied. The fingerlings were exposed for 10, 20 and 30 days in 10% sublethal concentration of 96 h LC50 of chromium (3.5 ppm). The gills exposed to sublethal concentration of chromium showed mild histological alterations during 10 days of exposure. However after 30 days, fusion of gill lamellae, hyp...
متن کاملEffect of Surfactant on External Morphology and Physiological Respiration of Freshwater Fish, Labeo Rohita’’
Surfactants are the major components of detergent used in household as cleaning products. In present study effects of surfactants (Surf excel) on external morphology and physiological respiration (breathing rate) of freshwater fish Labeo rohita have been reported. For this fishes were divided into two groups. Group-I fishes were placed under the concentration of 6.63 mg/lit surfactant and Group...
