effect of zinc cyanide on protein and certain metabolites content and some enzymes activitieswas evaluated in liver, muscle and gill tissues of the freshwater fish, cirrhinus mrigala, during exposure andfollowing cessation of exposure. fish exhibited significant alterations in the biochemical parameters in alltissues studied. levels of total protein decreased in all tissues, where as free amino...

this 4x2 factorial study compared the effect of four sites (a=siphon as upstream, andb=shahdera, c=sunder and d= balloki as 3 downstream sites) during low and high flow seasons of river ravion metal cconcentrations in muscles from cirrhinus (c) mrigala, a bottom feeder carp. while weight andlength of studied specimens did not differ significantly (p>0.05). overall metal accumulations appeared i...

Labeo rohita, Gibelion catla, Cirrhinus mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix were grown together for 365 days in triplicate ponds. Six iso-caloric feeds having varying protein levels i.e. 22, 24, 26, 28, 30 and 32% were prepared and supplemented to fish at 2% fish weight daily. Significantly, higher final average weight (793 ± 197 g) and total length gain (398 ± 40 m...

Water, sediment and fish samples of East Kolkata wetland were monitored using GC-ECD for residues of organochlorinated (OC) and synthetic pyrethroid (SP) pesticides. Among the OCs, HCH (α, β,  and ) were detected in water (0.02 – 0.1 μg/L) and in Cyprinus carpio (1.23-8.9 μg/kg) but none in sediments or in Oreochromis mossambicus. In Cirrhinus mrigala only α-HCH was recorded. In case of DDTs,...

Deltamethrin is a pyrethroid ester insecticide widely used in agricultural and non agricultural purposes in India, creates a serious threat to the environment as well as target and non target organisms. The present investigation was undertaken to study the effect of lethal (8mg/L) and sublethal (0.8mg/L) deltamethrin level on selected haematological indices of Cirrhinus mrigala. The target fish...

The toxic effects may include both lethal and sublethal concentrations, which may change the growth rate, development, reproduction, histopathology, biochemistry, physiology and behavior on target organisms and undesirable perturbations in the environment. The result of the present work i.e., observed percentage mortality of species of fresh water fish Cirrhinus mrigala when exposed to the 10% ...
