The present study reports the green synthesis of silver nanoparticles from leaves’ extract Mangifera indica (M. indica) and their antibacterial efficacy against Aeromonas hydrophila (A. hydrophila) in Cirrhinus mrigala (C. mrigala). prepared M. mediated (Mi-AgNPs) were found to be polycrystalline nature, spherical shapes with average size 62 ± 13 nm. C. (n = ±15/group) divided into six groups i...

The present study was conducted to evaluate the effect of traditional Bengal culinary practice on heavy metal content four carp species (Labeo rohita, Catla catla, Cirrhinus cirrhosus, and Hypophthalmichthys molitrix). Fish samples were collected from seven different farms located in Rajshahi district Bangladesh. processed cooked a currying method concentrations five metals (Pb, Co, Cr, Cd, Ni)...

The toxic effects may include both lethal and sublethal concentrations, which may change the growth rate, development, reproduction, histopathology, biochemistry, physiology and behavior on target organisms and undesirable perturbations in the environment. The result of the present work i.e., observed percentage mortality of species of fresh water fish Cirrhinus mrigala when exposed to the 10% ...

The effects of supplementing diets with levamisole on growth, immune response and resistance against pathogenic Aeromonas hydrophila were determined. Fish were assigned to three treatments with different level of levamisole (125, 250 and 500 mg kg ̄1 diet) and the control diet was prepared without levamisole. Cirrhinus mrigala were fed at 4% of their body mass for 60 days. Growth performance, en...

Pollution of water resources is a serious and growing problem, despite the existence of relevant legislations. Genotoxic studies on industrial pollutants are very important as they tend to accumulate in aquatic animals. Thus use of aquatic organisms to detect the genotoxicity is very useful in environment monitoring. For this chromosomal aberration test was employed to study genotoxicity caused...

Background: The use of probiotics in aquaculture is increasingly acknowledged, thanks to rising demand for environment friendly aquaculture. However, there an obvious need improve our understanding gut microbiology, as well the effective preparation and safety assessment probiotics. Methods: experiment comprised five treatments evaluate influence probiotic on water quality, growth body composit...

Histopathological studies were conducted on carp fingerlings of Labeo rohita, Catla catla and Cirrhinus cirrhosus during October 2003 to May 2004 from fish farms of Mymensingh area. Monthly samplings were done with 10 fish from each species with the help of seine net. Skin, muscle, gill and liver were collected, processed and stained in Haematoxylin and Eosin. Histologically carp fingerlings of...
