Behaviour and Respiratory Dysfunction as an Index of Malathion Toxicity in the Freshwater Fish, Labeo rohita (Hamilton)
The pollution of rivers and streams with chemical contaminants has become one of the most critical environmental problems of the century. As a result of the pollutants transport from industrial areas into the environment and their chemical persistence, many freshwater ecosystems are faced with spatially or temporally alarming high levels of xenobiotic chemicals (Brack et al., 2002; Diez et al.,...

متن کاملAnnual cyclical changes in the testicular activity of an Indian freshwater major carp, Labeo rohita (Hamilton).
Different male germ cells identified on the basis of histological and cytological characteristics in the testicular lobules of Labeo rohita have been grouped into spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and spermatozoa. The seasonal changes of the testis in L. rohita have been described according to its morphological peculiarities as well as to its variations i...
متن کاملAcute Toxicity and Behavioural Responses of Labeo rohita (Hamilton) to a Biopesticide “NEEM-ON”
The objective of this study was to determine the toxicity of the neem biopesticide azadirachtin (NEEM-ON, Brand name) on the freshwater fish ‘Labeo rohita’. Fishes were exposed to various concentrations of botanical insecticide azadirachtin for 96 h and the percent mortality was recorded. The 96h LC50 value determined by Finney’s Probit Analysis Method was found to be 42.66 ppm. Behavioural pat...
متن کاملAcute and subchronic toxicity of aflatoxin B1 to rohu, Labeo rohita (Hamilton).
Pathological alterations in various organs of rohu (L. rohita) fingerlings following acute (0, 7.50, 11.25 and 13.75 mg/kg body weight) and subchronic (0, 1.25 and 2.50 mg/kg body weight) single i.p. aflatoxin B1 exposure for 10 and 90 days, respectively, were investigated. Mortality (dose-dependent) was marked only during acute toxicosis. The changes observed in various organs were dose and ti...
