Carp Fish Farming Techniques: Best 10 Benefits Of it

Carp fish farming techniques are to cultivate carp fish profitably by adopting advanced methods. Those species of fish that are not aggressive, do not compete for food, live at different levels of the reservoir, and consume different levels of food, the cultivation of several species of fish together in the same pond is mixed farming.

And carp fish refers to domestic and foreign Rui fish. Carp include Katla, Rui, Mrigel, Kalibosch, Silver Carp, Grass Carp, Bighead Carp, Black Carp, and Common Carp. Generally, the fish live in 3 layers in the pond and eat separately.

They are not demonic; have Good immunity; grow very quickly or rapidly; are Easy to find chicks; consume small amounts of supplementary food; are Delicious to eat and in demand in the market; have economic value; Puppies can be produced by artificial insemination.

carp fish farming techniques

Different methods have been developed based on the environment and availability of inputs, farmers’ financial status, and knowledge, skills, and experience in different regions. Such as-

Traditional fish farming

Traditional fish farming is a method of fish farming that relies on the natural food of the reservoir at a low cost. Monsters and unwanted fish in the pond are not eliminated. No food or fertilizer is given to the pond from outside. In this method, the production is also very less.

Semi-intensive fish farming

Semi-intensive fish farming is a method of fish farming by scientifically preparing ponds, using regular fertilizers and supplementary feed, and stocking fry in medium density. In this method, fertilizers are used to produce more natural food.

The fry is stocked in ponds at specific densities by selecting species based on feeding habits so that food produced at different levels of the pond is properly utilized. If the natural food needs of these fish are not met, food is given according to the demand from outside.

Intensive fish farming

And the intensive method of fish farming is in a small place, in a short time, using fertilizer for high production, using natural food growth, and using a high quality complete supplementary food from outside to stock fry in high density. In this method, maximum opportunities for technology are used. Therefore, the modern system of regular water change and air circulation is done without stocking chicks in much higher density than the other two methods.

Pond site selection and preparation

If the selection of pond is not done properly, there will be problems in fish farming, fish will not grow properly, fish may be stolen, and problems may arise in the transportation of fry. The pond must be flood-free; The water depth of the pond is 2-3 meters; Loamy soil is best for ponds; Decrease the silt content of the pond floor.

But in no case more than 10-15 cm; There should be no large or leafy plants on the banks of the pond; The pond looks open and has a lot of light and air. 7-8 hours of sunlight per day should fall on the pond;

If it is an old pond, the fish must be killed first. It is best to dry out the pond through irrigation and catch monster fish and unwanted fish. Pond Banks and Bottom Development – ​​If there is excessive mud, garbage, and decaying organic matter at the bottom of the pond, it should be removed.

At the bottom of the pond, there may be various diseases, germs, and toxic gases. These can be removed by applying lime. Moreover, it is possible to keep the pH of pond water normal by applying lime. 1 kg of Kalichun is applied per percent in the pond.

Manure application method

A type of plant cell is produced naturally by producing food in the process of photosynthesis with the help of sunlight in pond water. These plant cells are known as primary producers. These are the food of cotton fish. Animals are also the favorite food of this fish. Therefore, fertilizers have to be applied to produce plants and animals naturally.

Fertilizer has to be used percent of the pond. Fertilizer levels may vary depending on soil and water depth in the pond. New ponds require more organic fertilizers than old ponds. Chemical fertilizers should be applied at least 5-7 days after the application of lime. TSP fertilizer should not be used immediately after lime application.

As TSP does not dissolve easily in water, it should be soaked in water for 10-12 hours before use. Water should be supplied to the pond immediately after fertilization. Otherwise, the effectiveness of nitrogen, an important component of organic fertilizers, decreases. If there is water in the pond, organic and inorganic fertilizers should be sprinkled throughout the pond.

Fish food in different layers in the pond

Generally, the fish live in 3 layers in the pond and feed separately. In the upper layer Catla, silver carp, and bighead feed on the upper layer of the reservoir. In the upper layers, these fish feed on green plant matter (phytoplankton) and animal matter (zooplankton). Mid-level roe fish live in this layer and feed on small animals, micro-insects, algae, and low-level carp, black carp, mirror carp, or carp, black carp mostly roam the lower level of the water body.

Stocking density and subsequent management

The stocking density in ponds depends on the farming system. High stocking of fry can be achieved if food is available, pond water changes are provided, and agitators are provided to oxygenate the water. Supplemental feeding The pond should be fed regularly from the time the fry is stocked. Mustard Kheil, rice bran, wheat bran, and fishmeal are supplementary food for fish. Good results are obtained if 20% non-vegetarian food is added to the fish supplement.

Food of grass carp

Grass carp are herbivorous fish. So grass carp should be supplied with green soft grass daily. One grass carp’s droppings can feed 5 carp.

Supplementary feeding management

The level of supplementary feeding depends on the abundance of natural food in the pond. However, in stocked ponds, 3-5 percent of fish weight per day gives good results. Fish’s biological digestion slows down in winter, thus reducing their food intake. For this reason, it is enough to give food at the rate of 1-2 percent of the weight of the fish in winter.

Mustard leaves should be soaked in a container with an equal amount of water for 12-15 hours if used with food. The average weight of 10% of the stocked fish should be drawn at least twice a month to check the growth of fish in the pond or the prevalence of disease and to determine the quantity of fish stocked in the pond.

Other maintenance

The success of fish farming depends largely on maintaining the water environment in the pond. Care should be taken to ensure that no decomposition occurs. Falling leaves in the pond can sometimes spoil the water environment.

To remedy this, the branches of the trees along the pond should be cut. Arrangements should be made to prevent the toxic water from drains from entering the pond. Water from any other source, nets, or other utensils should not be washed in pond water.

Partial accretion

The physical growth of fish does not accelerate after they reach adulthood. As a result, there is no need to breed in ponds after a certain age. So keeping big fish in the pond does not get much profit. Therefore, marketable fish should be caught. Besides, the physical growth of small fish is disrupted if the fish are stocked more than the maximum capacity in the pond.

Therefore, the small fish should be given a chance to grow by regularly catching big fish from the pond. If the big fish are caught, the small fish will have a chance to grow as there is more space in the pond. According to experts, the capacity of a carp fish pond is 224 kg per bigha. Therefore, more than 224 kg of fish per bigha should be extracted and sold. Generally, it is better to harvest the larger fish in the pond and give the smaller fish a chance to grow up when overfishing.

However, the number of fish that will be harvested in a month, the same number of fish fry of that species should be stocked in the pond. In this way, fish farming through extraction and stocking can produce much more. Catching larger fish through regular partial harvesting will allow smaller fish to grow.


After harvesting, it is expected that the remaining fish will grow and weigh more. The fish can be harvested after 6 months depending on the growth rate and market condition.
