Present study was performed to investigate the impact of sublethal concentrations of Diazinon on different behavioral aspects of Labeo rohita. LC50 of Diazinon for 96 hrs by static bioassay test was found to be 0.004ml/l. The fishes were exposed for 96 hrs. Diazinon exposure caused decrease in resting period, increase in opercular movement and air gulping, increase in jerk, threat and burst swi...

DAS, B. K., S. C. MUKHERJEE: A histopathological study of carp (Labeo rohita) exposed to hexachlorocyclohexane. Vet. arhiv 70, 169-180, 2000. ABSTRACT Indian major carp (Labeo rohita) were exposed to 1/10 and 1/5 sub-lethal doses of hexachlorocyclohexane during a 45-day trial period. Fish were sacrificed at the end of the trial period to study light microscopic changes associated with toxicity....

P * PChairman, Bihar State Environment Impact Assessment Authority, Govt. of India & Corresponding Author 1. Abstract: Signal transduction by xenobiotics in fish has gained much attention in the recent decade. Organophosphates and carbamates bind specifically to the membrane bound enzyme acetylcholinesterase affecting neural transmission. Since nervous system is one of the important physiologic...

There has been success with the use of plant ingredients in aquaculture as they are cheaper, biodegradable, biocompatible and growth promoters. Therefore, aim this study was to determine effects adding Carica papaya leaf diet Labeo rohita on feeding parameters. Feeding fishes different concentrations C. had an impact rate fish. Incorporation 10% feed enhances assimilation conversion efficiency ...

Investigation on the hydrography and fish fauna were undertaken from a period of February to September, 2012 at selective locations in river Baitarini, Jajpur. Twenty eight species of fish belonging to six orders, eleven families and nineteen genera were collected. Order Cypriniformes was most dominant constituting 33.33% followed by Siluriformes (30.3%), Perciformes (12.12%) and others like Mu...

Labeo rohita fingerlings were exposed to zinc metal toxicity (5 and 10 ppm) for duration of 5 and 15 days. The histological changes were studied in brain and liver of the treated fish. The brain tissues showed enlarged pyramidal cells with extensive vacoulation while severe necrosis, haemorrhage and degeneration of hepatocytes were witnessed in the liver tissues.

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...

The effect of dietary supplementation of commercial probiotics Bifilac® on growth of rohu, Labeo rohita fingerlings were evaluated. Experimental diet (ED) was supplemented with Bifilac® (3g/kg diet). Reference diet (RD) was not supplemented with Bifilac®. The feeding trial was conducted using L. rohita fingerlings (5.30±0.01 g) for 60 days in triplicates. The groups D1 and D2 were fed daily wit...

edwardsiella tarda is a versatile pathogen that could survive in different environmental conditions and infect economically important fish species. the whole cell antigenic proteins were extracted from e. tarda and assessed via western blot using anti e. trada rohu and anti e. trada rabbit serum. two strong reacted proteins with antibodies were recovered viz 61 kda and 47 kda from sds page gels...
