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...
