In temperate climate they spawn once during the spring. They know math well? Catla catla Profile Historical background Catla is endemic to the riverine system in northern India, Indus plain and adjoining hills of Pakistan, Bangladesh, Nepal and Myanmar, and has been introduced later into almost all riverine systems, reservoirs and tanks all over India. Aquatic weeds and terrestrial grasses form the major feed for grass carp in grow-out culture.
Female elephants in the herd The fish does not breed under pond condition and hence seed production is achieved through hypophysation. Seeds are easily reared in undrainable ponds of relatively smaller size. They are voracious eaters and show distinct preference for vegetable food materials such as grass, leaves, weeds, etc. The data on survival rate, quality of seed and their growth rate were obtained through personal contacts and telephonic conversation. The study inferred that hatchery owners were concerned on feed acceptability, high fecundity, spawn recovery, feed cost and the market.
Marketable sized fish are usually harvested through repeated netting. Identity Catla catla Hamilton, [Cyprinidae] FAO Names: En - Catla Biological features Body short and deep, somewhat laterally compressed, its depth more than head length; head very large, its depth exceeding half the head length; body with conspicuously large cycloid scales, head devoid of scales; snout bluntly rounded; eyes large and visible from underside of the head; mouth wide and upturned with prominent protruding lower jaw; upper lip absent, lower lip very thick; no barbels; lower jaw with a movable articulation at symphysis, without a prominent process; gill rakers long and fine; pharyngeal teeth in three row, 5. Its higher growth rate and compatibility with other major carps, specific surface feeding habit, and consumer preference have increased its popularity in carp polyculture systems among the fish farmers in India, Bangladesh, Myanmar, Laos, Pakistan and Thailand. Under composite fish culture in ponds it usually grows to over 1 kg in one year. Under the Indian system of composite fish culture in undrainable ponds, three Indian carps, viz.

The winters tale
Compared to common carp, the culture of grass carp started much later. National Fisheries Research Plan 73 pp. Spawning can be done naturally in specially prepared spawning ponds or induced by hormones incorporated in feeds or injected to fish kept in hatcheries.
The type of fish farming is one factor that determines production level. Turbidity do not seem to be essential for breeding of major carps.
The Fisheries Research Institute Ordinance. Carp Growing Basics Carps are hatched from eggs rather than born live and can grow to a weight of about 13 kg.
Asian American literature allows a further exploration of the past and traditional Asian philosophies Hormone Injection : Major carps do not breed in ponds due to the fact that the environmental factors which are responsible for spawning in natural habitats are absent in confined waters.
Female elephants in the herd Early-stage larvae remain in surface and sub-surface waters and are strongly phototactic.
Experiments on second spawning of major Indian carps in the same season by hypophysation. Crucian carp is considered[ by whom? Handling and processing Catla are marketed mostly in local markets, where they are sold fresh.
Usually only a portion of ingested food is digested and the rest is voided in semidigested or undigested form which, in turn, becomes choice food for the bottom dweller common carp Alikunhi, Sukumaran and Parameswaran, Pond fertilization with both organic and inorganic fertilizers, and supplementary feeding with the conventional mixture of rice bran and oil cake are the norm; however, the dosage and form of application vary with the farming intensity and inherent pond productivity.
Screens are mounted on the inner wall for discharging water during the operation. Carp, along with many of their cyprinid relatives, are popular ornamental aquarium and pond fish. It is one of the most commonly cultured ornamental fish out of hundreds of ornamental fish species there are.
The fish usually reach the size of about 30 mm in length after weeks of rearing. They reproduce and spread quickly, making them very dangerous to the aquatic ecosystem. Saheed, A. The feeding regime is similar but the rate is much higher.
During summer, the deeper portion of the pond retains water containing breeders. Cantonese and Shunde cuisines often use this fish to make fish balls and dumplings. Survival rates normally range from 30 to 40 percent; however, survival often remains low due to improper management. The data on survival rate, quality of seed and their growth rate were obtained through personal contacts and telephonic conversation.Breeding And Seed Production I Of Fin Fish And Shell Fish by P C,Thomas.

It provides real-life examples for the purpose of maximizing fish and seed production to support overall sustainability in aquaculture. Induced breeding of Indian major carps, Chinese carps and catfish: a manual for extension.

Freshwater Fisheries Research Station. The major carp species used traditionally in Chinese aquaculture are the black, grass, silver and bighead carp. In the s, the Pearl River Fishery Research Institute in China made a technological breakthrough in the induced breeding of these carps, which has resulted in a rapid expansion of freshwater aquaculture in China.
Fish species suitable for culture in undrainable ponds. There are two major systems of carp culture in Asia: the Chinese polyculture system where Chinese carps are cultured together, and the Indian composite fish culture system where the Indian major carps and Chinese carps are combined.
Induced breeding of Hypophthalmicthys molitrix, Labeo rohita, Catla catla and Barbados gonionotus can be conducted for commercial seed production using Compound S-GnRHa/Ovaprim TM (Salehin, ). It is used for breeding of these fishes as alternative of PG and HCG and is most commonly used for commercial breeding purpose.
