A feeding trial of ten weeks was conducted to evaluate the effect of microbial phytase supplementation on mineral digestibility in Labeo rohita fingerlings fed on canola meal-based diets. The experiment consisted of a reference diet and a basal diet. The reference diet was prepared according to the requirements of L. rohita and was used as a standard diet. The basal diet was made by replacing 3...

Food safety is currently a serious concern due to the health risks associated with food intake, particularly heavy metal contamination. Therefore, present study was conducted investigate metals concentration in water and fishes collected from Hakaluki haor, Bangladesh. Three important fish species, Labeo rohita, Cirrhinus cirrhosis, calbasu, together samples, were analyzed for (Pb, Cr, Cd), res...

“Ovaprim-C” manufactured by a Canada-based company, M/s Syndel laboratories, is in use world over today for induced spawning of fishes. Ovaprim-C contains 20 μg of Salmon gonadotropin releasing hormone (GnRH) and 10 mg of domperidone ml. The high cost and viscosity of Ovaprim proved a prohibitive factor. Another synthetic hormone “Ovatide” has been manufactured by a Mumbay based M/s Hemmo Pharm...

Breeding performance of stunted rohu Labeo rohita (Hamilton, 1822) was compared with normally reared rohu. Randomly selected and normal fishes were tagged together in a single earthen pond for broodstock development. Both groups exhibited growth enhancement during the development period, though found larger size than fishes, after rearing period. Gonadosomatic Index (GSI) female indicated simil...

Labeo rohita specimens were collected from local fish market of Aligarh to observe the hard structures providing the most suitable age estimate. Total length (TL) of each fish was measured from tip of snout to the longest fin ray of the caudal fin. Each fish was weighed separately on a weighing balance, and the age of each fish was determined by using cleithra, hyomandibular bone and urohyal bo...

A 12-week laboratory feeding trial was performed to evaluate the efficacy of two different algae based value added feeds (one containing Spirulina platensis and Enteromorpha intestinalis and the other with Phormidium valderianum and Catenella repens) against conventional (rice bran and mustard oil cake taken in 2:1 ratio, used as control) for fingerlings of Indian major carp, Rohu (Labeo rohita...
