Carp Fish Farming
The raising of carps, one of the most commonly farmed fish, has a long history. Are you interested in growing this family of fish commercially? Learn from our guide some basic information about carp fish farming, like which species are most commonly grown and what techniques are used to spawn them.
Carp is one of the most widely cultured fish. It is one of the most commonly cultured ornamental fish out of hundreds of ornamental fish species there are.
But those that are cultured represent just a few of the carp species that have farming significance out of a thousand available. Common carp, Indian carps, and Chinese carps are the species that have caught the attention of aquaculturists.
Carp Growing Basics
Carps are hatched from eggs rather than born alive and can grow to a weight of about 13 kg. They thrive on freshwater and grow best in the tropics where they spawn as much as four times a year. In temperate climates, they spawn once during the spring. Spawning can be done naturally in specially prepared spawning ponds or induced by hormones incorporated in feeds or injected to fish kept in hatcheries.
For natural spawning, farms use different media to collect the eggs. Some use tree branches, others plants, or fiber mats. The idea is to have a surface upon which eggs will be deposited upon release so that they can be easily transferred to nursery ponds. Eggs hatched within a week and fish larvae become fingerlings after about a month. They stay in the nursery for about a month before being transferred to grown-out ponds.
Carps are produced in monoculture (most common) or polyculture to take advantage of various food sources available. Common carps feed on small plants and zooplankton, other species, in addition, feed on tiny animals, mollusks, detritus, and dead plants. The type of fish farming is one factor that determines production level. Other factors include fish species, water temperature, and whether or not the fish are allowed to produce naturally or artificially fertilized. Under optimum conditions, yield could reach up to 800 g/m2.
You can pursue carp fish farming by breeding broodstock for sale to fish farmers, rearing them from broodstock, or by doing both. So that you could master all the aspects of growing this species, it is suggested that you grow the young ones until maturity. For specific values on the best fish stocking density, size and depth of the ponds, ideal temperature for raising carp to consult extension specialists, and research studies.
Fish Farm Equipment
Basic to any fish farm is a shed for protecting cultures; tanks or ponds for breeding and rearing and for holding the broodstock and larvae; pump for lifting or moving water. More specific requirements for a fish farm include a water supply network, electrical network, air blower, heater, aquarium, and laboratory instruments (for culture). Other necessities include feeds as well as a constant supply of water and electricity.

@hadi, Hi Hadi, Crap may spawn throughout the year but the best time is january to march and july to august. As per your question there are different methods used in different places so if you will mention your where about then i can give you the exact idea. Usually people in India use small ponds or cement tank, In indinesia people use Sundanese method and small ponds are use in china as well for breeding. I think this is the best process which is use in India for increasing the production. That is Fish seed production includes egg to spawn production for 3 days, spawn to fry nursing for 15-20 days, fry to fingerling rearing for 60-90 days and fingerling to yearling rearing for 8-9 months. Thus the carp seed may be categorized at its final size into spawn (6-8 mm size), fry (20-25 mm size), fingerlings (100-150 mm size) and yearlings (100-200 g weight).
