Partial dewatering or repeated netting can be done to harvest the  Rohu fish. “We currently export rohu-species fish to other countries, but they take a little longer to grow, particularly as importers only want bigger fish,” she said. If growing them in a fertilized pond they even grow faster, Ponds for the fish cultivation can be built. 5. The fry (20–25 mm) are reared in earthen rearing ponds at a density of 0.2 – 0.3 million/ha for 2–3 months and reach 80 – 100 mm in size.

An experiment was carried out in 18 earthen ponds to investigate the effects of the addition of common carp Cyprinus carpio (L.) and artificial feed o… Newly hatched rohu larvae are 3.5 – 4.5 mm in length. Genetically modified fish (GM fish) are organisms from the taxonomic clade which includes the classes Agnatha (jawless fish), Chondrichthyes (cartilaginous fish) and Osteichthyes (bony fish) whose genetic material has been altered using genetic engineering techniques. Commercial feed (Sunder’s feed) was used as control. Intensity of feeding varies with season, environment, size and the reproductive cycle. (2006a) reported maximum growth in terms of length, weight and specific growth rate (SGR) of 28.9 mm, 247.7 mg and 33.96, respectively. Mahuva oil cake 2500 kilograms per one hectare is used to kill the fish. For grow-out, fingerlings are stocked at a density of 5 000–10 000/ha in composite culture systems in which rohu comprise between 15-30 percent of the pond population. 25 Jul 2007 Rohu – Labeo Rohita Popular River water fish of Orissa India.
