Using the common carp Cyprinus carpio L. in polyculture ponds to increase both phytoand zooplankton availability has become a popular practice for the cultivation of plankti vorous fish, such as rohu Labeo rohita Hamilton. However, the dynamics of how common carp influences the environment and ecology in polyculture ponds are unclear. In the present study, the effects of various stocking densit...

Toll-like receptors (TLRs) play key roles in sensing wide array of microbial signatures and induction of innate immunity. TLR2 in fish resembles higher eukaryotes by sensing peptidoglycan (PGN) and lipoteichoic acid (LTA) of bacterial cell wall and zymosan of yeasts. However, in fish TLR2, no study yet describes the ligand binding motifs in the leucine rich repeat regions (LRRs) of the extracel...

labeo rohita fingerlings were reared in freshwater and exposed to different concentrations of lead nitrate. after the exposure, one fish was sacrificed from each dose and the gill arches were removed. the ultrastructural changes on the gills of this cyprinid fish were investigated through scanning electron microscope (sem). lead treated gill tissues showed certain marked changes such as uplifti...

The aim of the study was to investigate the physical difference in biochemical characteristics of spermatological and seminal plasma and also ultrastructure of spermatozoa in six carp species, viz. catla, Catla catla, rohu, Labeo rohita, kalbasu, Labeo calbasu, mrigal, Cirrhinus mrigala, silver carp, Hypophthalmichthys molitrix and grass carp, Ctenopharyngodon idella. Semen yield from different...

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 ...

the acute toxicity of salts of alkali and alkaline earth metals, such as sodium (na), potassium (k), calcium (ca) and magnesium (mg) were studied on the egg and larval stages of indian major carp labeo rohita (hamilton). the acute toxicity experiments were conducted followed by the range finding bioassay tests. the experiments were conducted in triplicates. the cumulative percentage of dead or ...

The study was conducted to evaluate the prevalence of food borne trematode infections in commercially important fish species of Pakistan such as, Labeo rohita (rohu), Cirrhinus mrigala (mori), Catla catla (thaila), Hypophthalmichthys molitrix (silver carp). For this purpose 222 different samples of fishes were collected from different water bodies i.e. Rawal Dam, Islamabad, Mangla Dam (Mirpur) ...
