Aim : To study the acute toxicity of λ-cyhalothrin in freshwater fish Labeo rohita by determining the 96 hours lethal concentration 50 (96 hrs LC ) and behavioural patterns of exposed fish. 50 Materials and Methods: A total 270 fingerling size fish were used to determine the 96 hours lethal concentration 50 (96 hrs LC ) of λ-cyhalothrin as per the guideline of Organization for Economic Co-opera...
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...
متن کاملErythrocyte Abnormalities in a Freshwater Fish, Labeo Rohita Exposed to Tannery Industry Effluent
The erythrocyte abnormality test was analyzed in kidney cells of freshwater fish, Labeo rohita exposed to tannery industry effluent. The 96h LC50 value of tannery effluent against fish was calculated by Finney method and it comes out to be 7.07%. Three sublethal concentrations on basis of 96h LC50 value (3.53%, 1.76% and 0.88%) were selected. Fishes were exposed to these concentrations for 24h,...
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...
