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 ...

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...

Fluctuating asymmetry (FA), often used as indicator of environmental stress, was evaluated in gill rakers and filaments of Labeo ogunensis from Ogun river, Southwest Nigeria. Mean length and weight of 13.68 +/- 1.28 cm and 59.40+17.48 g were respectively recorded. The gill rakers (t = -0.919) and filaments (t = -1.150) from both sides were not significantly different. The gill filaments recorde...

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...

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...

Curcumin, an orange-yellow phytochemical, hydrophobic and polyphenolic compound of turmeric (Curcuma longa Linn.), has been known to be a potent immunomodulatory agent in mice, horse, human and other higher vertebrates. In the present study, we have found its immunostimulatory properties in fish Labeo rohita (H.). Curcumin at low doses (15 and 1.5 μg) significantly (P<0.05) increased some non-s...

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 ...
