How much does carp farming cost roughly?

SummaryThe cost of farming carp in one mu of land is around 20,000 yuan, and broodstock are generally farmed in about 2 mu of land. When farming broodstock, pay attention to selecting those with a good body shape, strong vitality and no external injuries. Broodstock can spawn from March to August, but the spawning volume is most vigorous from April to June.

1. Pond selection

The price of an ordinary one-mu pond is about 600 yuan/year, and the farming area depends on the specific circumstances.

2. Fry selection

At present, the price of carp fry on the market is about 400 yuan/10,000 tails. If carp fry are stocked alone at 120,000-150,000 tails/mu, the cost of the fry is about 4,800 to 6,000 yuan.

3. Feed

Feed is indispensable for farming carp, and it is the largest expense for carp. Calculated per mu, the feed for the fry is about 15,000 yuan/year

4. Fishery drugs

For farming carp, the cost of fish medicine is about 300 yuan a year.

5. Electricity

Generally, the electricity cost for farming one mu of carp is about 100 yuan/year.

Therefore, the cost for farmers to farm carp in one mu of pond is about 20,000 yuan.

How to farm high-yield carp

1. During the farming process, carp generally mature at the second instar, but some good individuals can also mature at the first instar. Carp can spawn from March to August, but April to June is the most vigorous spawning period for carp. Carp eggs are generally laid in shallow water areas, or among aquatic plants in river bays. The number of eggs laid varies according to age and fish size, generally ranging from 150,000 to 800,000. At a water temperature of about 20°C, the eggs can hatch into fry in about 5 days.

2. When farming carp, fry with a good body shape and strong vitality should be selected. Generally, fish with a body length to body height ratio of 3:1 are selected for farming. It is best to ensure that female fish are at 2 winters of age and weigh more than 1.5 kg, and male fish are kept at 2 winters of age and weigh more than 1 kg. Carp that are spawning for the first time and declining carp have poor spawning quality and should not be selected as broodstock for breeding.

3. The pond for farming broodstock is generally about 2 mu, and the water depth should be kept at about 1.2 m. A place with good lighting and convenient water sources should be chosen. Generally, about 200 kg per mu is stocked. Before stocking, the pond should be disinfected with lime and bleaching powder. During artificial breeding, male and female fish are separated to prevent them from mating and spawning on their own.

4. For broodstock cultivation, high-protein feeds such as soybean cake, silkworm pupae and fish meal can be fed, and broodstock feed can also be fed. It is rich in ve and other vitamins, which can promote the development of broodstock and improve stress resistance. During the rearing process, attention should also be paid to regulating water quality, maintaining a slight flow of water, and regularly injecting new water to stimulate the development of the broodstock's gonads.

5. Start feeding the fry early, and strive to transition to feeding with a complete formula feed as early as possible. Broodstock grow especially fast during the peak feeding period, and both body length and body weight increase rapidly. The more feed they need, the more the feeding amount should be increased at this time. Feeding should be carried out by adhering to fixed quality, fixed time, fixed location and fixed quantity. In this way, the fish stock can achieve a higher-quality spawning volume.
