Genetic characterization of the base population of a breeding program is useful in monitoring changes in the genetic structure that might occur over generations. By using microsatellite DNA markers, we have analyzed the genetic population structure of the Jamuna, Padma and Halda river samples of Catla catla maintained in a Brood bank of the Department of Fisheries, Bangladesh. We detected a tot...

In this study, concentrations of Cd, Cr, Mn, Pb, and Zn were determined by flame atomic absorption spectrophotometer (FAAS) in edible muscle tissues a total 25 fish samples belonging to five species viz., Hypophthalmichthys nobilis (Bighead), Wallago attu (Buhari), Catla catla (Catla), Clarias batrachus (Mugree), Labeo rohita (Rohu) marketed Kathmandu, Nepal evaluated potential health risks for...

Composite culture of edible fishes (common carp, Cryprinus carpio; silver carp, Hypopthalmithys molitrix, grass carp, Ctenopharyngodon idella; catla, Catla catla; rohu, Labeo rohita; and mrigal, Cirrhinus mrigala) in rice fields in the Cauvery delta of Tamil Nadu, southern India, resulted in 81.0% reduction in the immature mosquito population of anophelines and 83.5% of culicines. Analysis of f...

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...

The present Study proposed to evaluate the body composition of Catla catla and Hypophthalmichthys molitrix collected from southern Punjab, Pakistan. Collected fishes samples werebrought fisheries lab for further analysis. mean value water, fat, protein ash as water is 75.1%; Ash in wet dry weight 4.07 16.4; Fat 5.2 20.8; Protein content 15.62 62.66 respectively C. catla. ranges 77.27%; 4.20 5.2...

Changes in the quality of Catla (Catla catla) stored immediately (0 h) ice, after six (6) hours ice and at ambient temperature soon catch was investigated. The samples were examined by sensory (organoleptic rigor mortis progress) biochemical parameters (total volatile base nitrogen, trimethylamine nitrogen pH). proceeded faster fish (28°C-30°C) than those (0°C). duration full stage total period...

The antioxidant and growth stimulating properties of seeds of Achyranthes aspera were evaluated on UV-B irradiated Catla catla (catla) larvae. Catla larvae (initial weight: 1.2 ± 0.01 mg) were fed with four different diets--D1, D2 and D3 containing 0.1, 0.25 and 0.5% seeds of A. aspera and D4, control diet for 35 days. The larvae were then exposed to UV-B radiation (80 μW/cm2) on every alternat...

Myxosporean taxonomy which is traditionally based on the morphology of the myxospore stage, is in a state of flux given new insights provided by the expanding dataset of DNA sequences. To date, more than 40 species of Thelohanellus from India have been described according to morphometric characteristics. Nevertheless, molecular data on these histozoic myxosporean parasites of freshwater fish ar...

From the Aeromonas hydrophila strain, five different types of antigens such as heat killed antigen, whole cell antigen, heat killed antigen with antiserum, whole cell antigen with antiserum and nucleotide antigens were prepared and injected into the experimental fish (Catla catla) groups for the study of immunomodulation. Analysis of immunogenicity of antigens against the fish Catla catla was e...
