In acute toxicity (96 hr) experiment the fingerlings of freshwater fish Labeo rohita was exposed to tannery, electroplating and textile mill effluents. The LC0 and LC50 concentrations were 15% and 20% for tannery effluents, 3% and 6% for electroplating effluents and 18% and 22% for textile mill effluents respectively. It was found that, electroplating effluent was more toxic than tannery and te...

In India, more than 104 species of Myxobolus have so far been reported infecting freshwater as well as marine fishes. The study focuses on the description of a new myxosporean species, Myxobolus sp.n PKB 2014 from the gill lamellae of an Indian major carp Labeo rohita. The species have been described on the basis of morphological characterization of the spores, tissue architecture and 18S rDNA ...

UNLABELLED Interleukin-10 (IL-10) is a pleiotropic cytokine and plays an important role in inflammation, immunoregulation and the pathogenesis of various diseases. Therefore, it is our interest to isolate, clone, sequence and characterize IL-10 gene from the fish Labeo rohita (Lr). The gene was amplified using genomic DNA isolated from head kidney with primers designed on conserved sequence hom...

Arsenic and hexavalent chromium toxicity results from their ability to interact with sulfahydryl groups of proteins and enzymes, and to substitute phosphorus in a variety of biochemical reactions. Alanine aminotransferase (ALT; E.C: 2.6.1.2) and Aspartate amino transferase (AST; EC 2.6.1.1) play a crucial role in transamination reactions and can be used as potential biomarkers to indicate hepat...

Abstract We have evaluated the effects of different fish feeds on body composition, growth, and enzyme activities Labeo rohita (Rohu). In total, 240 fishes between average weights 24.77±2.15g were studied. The treatments applied in a completely randomized design, with 4 60 each. Treatments consisted four [Oryza (T1), AMG (T2), Aqua (T3), Supreme (T4)]. Body growth performance, evaluated. There ...

Interleukin-10, an important regulator of both the innate and adaptive immune systems, is a multifunctional major cytokine. Though it is one of the major cytokines, IL-10 from the Indian major carp, Labeo rohita, has not yet been characterized. In the present study, we report large scale production and purification of biologically active recombinant IL-10 of L. rohita (rLrIL-10) using a heterol...

Motile aeromonads isolated from the intestines of farm-raised freshwater fish such as Catla catla, Labeo rohita and Ctenopharyngodon idella have been characterized to species level. Morphological and physiological grouping revealed 61% Aeromonas hydrophila, 30% Aeromonas caviae, 7% Aeromonas sobria and 2% which remained unidentified. Hemolytic activity was detected mostly in A. hydrophila, whil...

Degenerative histopathalogical alterations were seen in liver due to chronic exposure of the fish, Labeo rohita to chlorides of chromium, nickel and zinc for 30 days. However, more severe degenerative changes were observed in case of zinc chloride exposed fish than nickel chloride and chromium chloride treated fishes, indicating more toxic nature of zinc chloride. There were enlarged nuclei, co...

We monitored the Condition Index (CI) of Labeo rohita, which is an important indicator to evaluate health and well-being cultured fish. In this pilot project, we initiated culture with rohita as a candidate species in 12 rain water stocked ponds at Diamond Harbour during March, 2022 October, computed monthly condition index considering mean weight length (n = 65 for each pond). Simultaneously m...

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...
