This graceful Indo-Gangetic riverine species is the natural inhabitant of the riverine system of northern and central India, and the rivers of Pakistan, Bangladesh and Myanmar. In ponds, the fry and fingerlings exhibit schooling behaviour mainly for feeding; however, this habit is not observed in adults. Sometimes snakehead, (Channa striata), are al-so stocked at 500 fish/ha to control trash fish and insect pests in ponds. For maintaining a profitable fish farming business, you have to go through some step by step process. They are bottom feeders and eat algae and small animals. In this form of culture, which includes multiple stocking and the multiple harvesting of fish larger than 300 g, primary treated sewage is provided to the fish ponds as the main input. The adoption of new technologies could help Jamaica realise the potential of its currently stagnant aquaculture sector, …, The ambitions, and profits, of Indian aquaculture operators are constantly undermined by poor access to reasonable loans…, Up to 10 percent of the cichlid fish in Ghana’s Lake Bosomtwe can be traced to escapees from a short-lived illegal Nile …. The fecundity varies from 226 000 to 2 794 000, depending upon fish size and ovary weight; on average it ranges from 200 000-300 000 eggs/kg BW. - Bhumika Animal Breeder Fam.

We have the biggest fish hatchery in India where artificial breeding is done under controlled conditions so as to produce healthy species. Handling and processing Rohu is the most preferred species among the cultivated Indian major carps. Due to its wider feeding niche, which extends from column to bottom, rohu is usually stocked at relatively higher levels than the other two species. Owing to their purity, high freshness, safe usage, and tangy taste; these products are extensively used. In extensive systems, with a targeted production level of 2-3 tonnes/ha, the cost of production is about USD 0.30/kg, while the costs increase to USD 0.5-0.6/kg in semi-intensive culture, where the targeted production is 4-8 tonnes/ha. Information on its culture is available only from the early part of the 20th century. but there are so many small fishes in the ponds, can’t quantify. Area(Hect.) While riverine collection of seed was solely meeting the requirement for culture of the species until the first half of the 20th century, the success in induced breeding in 1957 and the assured seed supply thereafter was the major factor for the development of its culture in freshwater ponds and tanks. Labeos have a thick-lipped, sucking mouth on the underside of the head and two to four small mouth barbels. ), has been a major problem for rohu compared to other carps, causing reduction in growth and sometimes mortalities. The higher consumer preference and market demand for rohu during recent years have also led to the practice of two-species culture with catla. Furthermore, the compatibility of rohu in polyculture systems with regard to habitat preference and feeding habits is good. They were transported from the rearing pond site to the breeding pool through a hammock or career tank The species has also been introduced in many other countries, including Sri Lanka, the former USSR, Japan, China, the Philippines, Malaysia, Nepal and some countries of Africa. a 15-20 days nursery phase for raising fry, followed by a two-three months phase for fingerling production. When using this approach we carefully consider interactions between hatchery and natural-origin fish in the context of our overall goals for threatened or endangered fish. It is a fast growing species and attains about 35-45 cm total length and 700-800 g in one year under normal culture conditions. Greater susceptibility of the species to Argulus infection over catla and mrigal in polyculture systems is another common problem, especially at higher stocking densities. Export to South-East Asian and Middle-East countries. Aquatic insects are eradicated by the application of a soap-oil emulsion or removed by repeated netting before stocking. About Fish Hatchery . The high growth potential of the Indian major carps has attracted the attention of several tropical South-Eastern Asian and Middle-Eastern countries. Our fish hatchery produces Chital Fish Seed, Singhi Fish Seed, and Pabda Fish Seed. Almost all the rohu produced from aquaculture is consumed in local markets. The adoption of intensive farming practices, unregulated use of inputs and lack of scientific know-how among the farmers has led to increased disease incidence. In certain areas, brick-lined or cement tanks are also used as nurseries. While the adoption of scientific carp culture in recent years has been realising production levels of 3-5 tonnes/ha/yr, such practices are limited to only a few small areas. The higher price of commercial feeds has been forcing farmers to resort to the conventional bran-oil cake mixture, usually supplied in dough form, thus leading to wastage and deterioration of water quality. Healthy rohu fingerlings were procured from a government fish seed hatchery in Lahore and acclimatized under laboratory conditions for two weeks prior to this feeding trial. Rohu is a polygamous fish and also seems to be promiscuous. The hatchery is certified by NFDB. Since rohu forms an important component of the carp polyculture system, it can be expected that there will be a two-fold increase in its production in India by 2015. Rearing fingerlingsNursery phase Three day old hatchlings, measuring about 6 mm, are reared up to fry of 20-25 mm in small earthen nursery ponds of 0.02-0.1 ha. Other factors are expected to influence further growth in the farming of Indian major carps, including: The official production figures often do not represent a true picture, due to the lack of appropriate and uniform data collection mechanisms.

Rohu breeding in FRP carp hatchery activities in the breeding pool Rohu breeders were selected male to female in 1:1 ratio in number and weight for breeding programme. Long-distance transport of these ice-packed fish in insulated vans is a common practice in countries like India, where rohu are even transported over 3 000 km by road. When pituitary extract is used, females are injected with a stimulating dose of 2-3 mg/kg BW followed by a second dose of 5 to 8 mg/kg after a lapse of six hours; males are given a single dose of 2-3 mg/kg at the time of second injection of the female. Fresh Machli is a fish farming company located in Jamshedpur (TATA), Jharkhand, India. The latter type of aquaculture is occurring in over 100 000 ha of ponds in the Koleru lake region of Andhra Pradesh, India, in which rohu forms more than 70 per cent of the stock. The non-availability of commercial feed, forcing the farmers to resort to the conventional bran-oilcake mixture, is another limiting factor for the growth and survival of fry. 6 HATCHERY SYSTEMS It has been recognized as multiplier unit of CIFA. The fingerlings reared in crowded conditions for over one year, and 150-300 g in size) are used as the stocking material. The seed rearing normally involves a two-tier system, i.e. Rearing Fingerlings in Rohu Fish Farming:- Rohu fry should be reared along with mrigala and catla at equal proportions with combined densities of 0.2 to 0.3 million fry per 1-hectare pond.Generally, the nursery raised fry of 25 mm length Rohu should be reared further for the length of 100 mm and weight of 10 grams to 15 grams fingerlings to raise in the main pond. Improvements in induced breeding and seed production, which have removed the reliance on the capture of natural riverine seed. However, the tendency of farmers to increase income per unit area has led to an excessive use of fertilisers, proteinaceous feeds and chemicals that may have detrimental effects on the environment. ★★★★★ However, the percentage of rohu, even within this six-species combination, is retained at 35-40 per cent, similar to that in the three-species polyculture system. The spawning season of rohu generally coincides with the south-west monsoon, extending from April to September. Today, hatcheries provide the foundation for the state's popular recreational fisheries and the many jobs that depend on them. The compatibility of rohu in polyculture systems with other carps has already been established. Governmental regulation and control over the domestic marketing system for these aquaculture products are almost non-existent; thus the market price is influenced mainly by demand and supply.

In the Koleru lake area of Andhra Pradesh, the centre of commercial carp farming activity in India, the practice commonly involves the rearing of rohu and catla in two-species farming, with rohu constituting over 70 percent of the stock. The nibbling type of mouth with soft fringed lips, sharp cutting edges and absence of teeth in the bucco-pharyngeal region helps the fish to feed on soft aquatic vegetation which do not require seizure and crushing. On the other hand, adults show a strong positive selection for most of the phytoplankton. The hatchery attracts up to 50,000 visitors annually, many of whom come to watch egg collections from steelhead, coho salmon and chinook salmon returning to the hatchery. A large share of the production still comes from extensive farming involving stocking and fertilisation as the inputs and achieving more modest production levels of 1-2 tonnes/ha/yr. Body bilaterally symmetrical, moderately elongate, its dorsal profile more arched than the ventral profile; body with cycloid scales, head without scale; snout fairly depressed, projecting beyond mouth, without lateral lobe; eyes dorsolateral in position, not visible from outside of head; mouth small and inferior; lip… In India, it has been transplanted into almost all riverine systems including the freshwaters of Andaman, where its population has successfully established. Catla reach 1.5-2 kg and rohu 1-1.5 kg in one year with 80-95 percent survival and overall yield of 10-13 mt/ha/year. Being a low input-based system, carp culture has not generally been perceived as a threat to the environment. Development of processing and value-added products. In its early life stages rohu prefer zooplankton, mainly composed of rotifers and cladocerans, with phytoplankton forming the emergency food. 4★ In general, 0.15-0.2 million eggs/kg of female are obtained. Improvements in feeding and health management. Rohu is a highly preferred carp and fetches comparatively high market prices. Even without the provision of supplementary feed, this system produces 2-3 tonnes/ha/yr; with supplementary feeding, this can be increased to 4-5 tonnes/ha/yr. Judicious feed management, therefore, requires attention in order to enhance the profit margin. 5★ The compatibility of rohu with other carps like catla (Catla catla) and mrigal (Cirrhinus mrigala) made it an ideal candidate for carp polyculture systems. However, increased emphasis on intensification for enhancing production in recent years has resulted in increased use of chemical fertilisers, feeds, therapeutics, drugs, chemicals, etc., which pose some concern. This type of hatchery possesses three principal components, viz., spawning/breeding tank, incubation/hatching tank, and water storage and supply system. Furthermore, the occurrence of decayed organic matter and sand and mud in its gut suggests its bottom feeding habit. ★★★★★ histo-biochemical parameters of rohu fingerlings. Considering its importance in the culture system, emphasis has also been given to its genetic improvement through selective breeding in India. Sex wise total weight of the breeder was calculated by a spring balance. Supplementary feed forms the major input, constituting over 50 per cent of the recurring expenditure in growout. Karnal: Bultana: 10: 1-Rohu 2-Catla 3-Mirgal: 3. Post-harvest processing and value-addition of this species is almost non-existent at present in any of the producing countries. Central Institute of Fisheries Education, Mumbai, India. Limited experiments conducted on rohu and silver carp with Hce 766 Vet + Progesterone have yielded positive results. Several factors have enhanced the status of the farming of the Indian major carps: On the other hand, while the inter-generic hybridisation of mrigal, rohu, catla, grass carp and common carp has been attempted, the hybrids did not show any genetic advantage over the parent stocks. ©2020 ‐ Hatch Accelerator Holding Limited, 7/8 Liberty Street, Cork, T12T85H, Ireland, Hatch Accelerator Holding Ltd, 7/8 Liberty St, Cork, T12 T85H, Ireland; CRO 617308.

While induced breeding through hypophysation has been the common practice since the development of the technology in 1957, several synthetic commercial formulations of purified salmon gonadotropin and dopamine antagonists such as Ovaprim, Ovatide and Wova-FH have also been successfully used in recent years. The overall survival in these fingerling rearing systems ranges from 60 to 70 per cent. In water bodies where multiple stocking and multiple harvesting are practised, the harvesting of larger sizes (300-500 g) is usually initiated after six-seven months of culture, and the smaller ones are returned to the pond for further growth. A fish breeder trying to show Fish Breeding System. | In the fingerling stage, there is a strong positive selection for all the zooplanktonic organisms and for some smaller phytoplankters like desmids, phytoflagellates and algal spores. Annual fish production totals 120,000 pounds. Bangladesh is also expected to enhance farmed rohu production. At first, a hormone injection was given to the fish. Learn more about WDFW's hatchery facilities and how they help the department manage fish across the state. In many cases, although the stocking of a single species is normally advocated, farmers resort to stocking all three species of the Indian major carps. Fish Hatchery Farming is an excellent option to choose. Hatcheries, or artificial propagation, are one tool to help support wild populations and provide fish for harvest. 3★ Seed supply Induced breeding of rohu has been catering for almost the entire seed requirement in all the countries where it is cultured, although riverine collection still forms the seed source in certain small areas.
