A sixty-day study was carried out to compare the growth of hybrid between Labeo rohita (rohu) and bata (bata) with one parental species, rohu. The fertilization hatching rates found be lower in than those After three days spawns were reared earthen nursery ponds for sixty days. weight first ten and, length following fifty obtained compared rohu significant difference observed. showed faster rat...

The study was carried out to identify muscle protein patterns and gut protease activity of rohu (Labeo rohita), catla (Catla catla), climbing perch (Anabas testudineus) spotted snakehead (Channa punctatus). Twelve percent Polyacryleamide substrate SDS-PAGE done visualize the enzyme after casein hydrolysis pattern species. Three alkaline proteases different molecular weight were observed in rohu...

Rohu (Labeo rohita) is a species of fish of the carp family cyprinidae. A survey was carried out from September, 2012 to August, 2013 to study the prevalence of bacterial ulcerative disease in L. rohita, cultivated in a freshwater farm located at Moongilthuraipattu Village of Villupuram District, Tamil Nadu, India. To mimic the infection in healthy fish, organs such as liver, gill and ulcerativ...

Background: An experimental study was conducted to examine growth performance and economic feasibility of Cyprinus carpio (Linnaeus, 1758) Labeo rohita (Hamilton, 1822) vis-à-vis their improved strains viz. Amur carp Jayanti rohu, in synchronously integrated rice-fish system at high altitude terraced paddy-fields (HATPF). Methods: The fields were stocked with fingerlings (6.95±0.67 g) a density...

Aquaculture, as a promising food industry, is expected to meet the demand for quality food from the increasing human population. As the diet is critical for feeding farm fish, such a faster growth in the industry is destined to create stress in the fishmeal market to supply diets to the tune. In this context, here, we studied the protein content of 20 plant ingredients, including aquatic weeds,...

In the present study short-term (96 hr) toxicity of mercury in relation to water hardness (270 and 560 mg/l) and temperature (16 degrees C and 35 degrees C) to the fingerlings of Indian major carps, i.e. catla, rohu and mrigal has been evaluated using static bioassay. The LC5o indicates that both water hardness and temperature played significant role in mercury toxicity. The test fishes were fo...

The study was conducted to evaluate the effect of antibiotic on shelf life in rohu fish, Labeo rohita (Hamilton) under ice storage condition. Oxytetracycline (OTC), the most widely used antibiotic, was fed to rohu (average body weight 16.0 g) at the rate of 2 g/kg through fish diet for 5 days and their shelf life was determined in iced condition. Organoleptically, fish were found to be acceptab...

Aeromonas hydrophila is a Gram-negative bacterium that causes high mortality in different fish species and at different growth stages. Although vaccination has significantly contributed to the decline of disease outbreaks in aquaculture, the use of oral vaccines has lagged behind the injectable vaccines due to lack of proven efficacy, that being from primary immunization or by use of boost prot...
