Discover the secrets of carp farming
Hello everyone, today we are going to talk about carp farming methods. As one of the four famous major fish in China, carp has a long history of breeding. What is intriguing is that with the development of the times, today's carp farming has a new look, whether it is the breeding model or the management methods, have become more scientific and professional. So, what do you need to pay attention to in a complete modern carp farming process? Let me go one by one for you now.
The carp is a freshwater carp that originated in the Asian region. As early as the 5th century B.C., there were records of artificial carp breeding in China.
Carp is a warm-water fish with a slightly flattened body and a sucker-shaped mouth. Docile temperament, tenacious vitality, resistance to low oxygen and high turbidity.
Under good conditions, carp grows rapidly, growing to about 600 grams in 1 year and reaching conventional market size in 2 years.
The carp meat is delicate, delicious, rich in protein, unsaturated fatty acids, etc., and has high nutritional value.
Carp has strong adaptability such as cold resistance, high turbidity resistance, and low oxygen tolerance, and is relatively easy to manage in aquaculture.
Carp growth requires sufficient dissolved oxygen, and the amount of dissolved oxygen should be kept above 4 mg l.
Carp have a wide tolerance range for pH, with the optimal pH being 65-8.5。
High concentrations of ammonia nitrogen can cause poisoning to carp, so it is important to keep ammonia nitrogen levels within a safe range.
Moderate flow is good for oxygenation and metabolite excretion, but too fast flow can also cause a burden on carp.
Carp is a warm-water fish, and the optimal water temperature is 20-30, and a temperature below 15 or above 35 will affect its growth.
The pond area should be determined according to the actual breeding scale, generally 400-800 square meters is appropriate, and the water depth is 1-15 meters is preferred.
It is better to have a rectangular or round shape of the pond, and a deep ditch is set in the middle of the bottom, which is conducive to sewage discharge. The water outlet and water inlet should be set separately.
Before seedling, the pond should be thoroughly cleaned, lime should be sprinkled for disinfection, and the facilities should be inspected and repaired to ensure that nothing goes wrong.
You can go to a professional carp nursery to purchase artificial seedlings, the quality is reliable, but the cost is higher.
Catching natural carp fry in wild waters is inexpensive but of varying quality.
Carp is an omnivorous fish that likes to eat a variety of plant and animal residues, and can also be fed special fish food.
The amount of feeding is about 15%-20% of body weight in juvenile stage and 3%-5% in adult stage, 2-3 times a day.
The feeding time and method should be fixed, pay attention to even feeding, and avoid wasting and polluting the water body.
It is important to maintain a good pond environment by changing the water regularly, salvaging floating debris, testing the water quality, etc.
Common bacterial diseases include gill cleft spot disease, carp spring poison, etc., and the symptoms are mostly ulcers and abnormal swimming.
Viral diseases, such as hemorrhagic viruses, are more harmful and cause a large number of deaths.
Common insect pests of carp include fish maggots, anchor snails, etc., which can directly parasitize the fish body or indirectly harm them.
Paying attention to pond hygiene and timely putting disinfectants and medicines can effectively prevent and control diseases. When the disease occurs, the affected fish should be isolated first and then taken in time.
In general, carp can be harvested after 15-18 months of rearing.
It can be harvested manually by trawling, casting nets, etc., or harvested using mechanized equipment.
In addition to being eaten directly, fresh carp can also be frozen and salted to meet different needs. Fish fertilizer and fishmeal are also important ways to utilize.
As a freshwater economic fish, the carp market has broad prospects. As long as every link is well controlled, a moderately sized carp farm can achieve considerable economic benefits.
With the continuous improvement of people's living standards, the demand for high-quality fish products is also increasing day by day. It is foreseeable that the carp aquaculture industry will face greater development space in the future.
As a well-known high-quality freshwater fish, carp is undoubtedly a breeding species with great potential. As long as we have made great efforts in all aspects of breeding environment, seed selection, daily management, etc., and operate in strict accordance with the standard requirements, I believe that we will be able to achieve ideal breeding results. As a sunrise industry, carp farming will bring unprecedented new opportunities and new impetus to the majority of fishermen, let us seize the opportunity together and share the future development dividends.
What water quality conditions are required for carp to grow? Carp need water quality conditions with sufficient dissolved oxygen, moderate pH value, and low ammonia nitrogen content, and at the same time, there should be no excessive water flow disturbance.
Which seed should be used for carp farming? Generally, it is recommended to choose artificial seedlings with reliable quality, although the cost is high but the quality of safe wild seedlings is uneven, and it needs to be carefully selected.
How many times a day should carp be fed? How much? Juveniles are fed 2-3 times a day, and the amount of each feeding is about 15%-20% of body weight; The grow-out stage is also 2-3 times, but the feeding rate drops to 3-5%.
What are some common pests and diseases of carp? Bacterial diseases such as gill cleft disease, viral diseases such as hemorrhagic viruses, and insect pests such as fish maggots and anchor snails all need to be controlled.
When is the best time to harvest carp? Generally, after 15-18 months of culture, the carp can reach the appropriate market size, and then it can be harvested and processed.
