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...

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...

“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...

We designed a field survey (the entire river length; not dammed: First and Second plateaus; dammed: Third Plateau) to test the hypothesis that the cascade of reservoirs promoted a reduction in species richness and changed the composition of Oligochaeta assemblage along the Iguaçu River. Changes in environmental variables and in richness and composition of Oligochaeta were summarized by Canonic ...
