Characteristics and functional efficacy of digestive proteases of Catla catla, catla, Labeo rohita, rohu and Hypophthalmichthys molitrix, silver carp were studied. Total protease activity was significantly (P < 0.05) higher in rohu (1.219 ± 0.059 U mg protein min) followed by silver carp (1.084 ± 0.061 U mg protein min), and catla (0.193 ± 0.006 U mg protein min). Trypsin activity of silver car...

The number, shape and sizes of intermuscular bones have been studied in table size (around 1200g). rohu, catla and mrigal after microwave cooking and dissection. Carp intermuscular bones have varied shape and size. These bones are of two types, Y pin bones and straight pin bones. Total number of pin bones are highest in mrigal (110 nos.) followed by catla (108 nos.) and rohu (104 nos.). Y pin b...

The research investigated the impacts of inclusion of column feeder rohu (Labeo rohita) on growth and production in freshwater prawn-carp-mola polyculture system for a period of 172 days. Four stocking densities of Rohu were maintained as 500, 1,000, 1,500 and 2,000 ha -1 in treatment R500, R1000, R1500 and R2000, respectively in triplicates. All ponds each 120 m 2 were stocked with juvenile fr...

Background: Feed cost mainly constitutes 40-60% of total aquaculture production expenses, due to the inclusion expensive animal-derived ingredients feed industry. Studies suggested that herbivore and omnivore fish species can consume higher level carbohydrate (150–300 g/kg starch) as compared carnivore fish. However, lower utilization in fishes is less understood till date. In present work, It ...

The myostatin (MSTN) is a known negative growth regulator of skeletal muscle. The mutated myostatin showed a double-muscular phenotype having a positive significance for the farmed animals. Consequently, adequate information is not available in the teleosts, including farmed rohu carp, Labeo rohita. In the absence of experimental evidence, computational algorithms were utilized in predicting th...

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...
