Carp Breeding Techniques Bring High Profits

Carp is one of the popular freshwater fish species, raised in many places with many different environmental conditions. Therefore, the current model of commercial carp farming is constantly developing in many parts of the country and bringing great profits. We invite you to refer to the article below for more useful information about carp farming techniques Please.

Preparing the fish pond

Before raising fish, the pond must be prepared according to the following steps:

Repairing pond banks, checking culverts, clearing banks.

Slapping or draining the pond, clearing the duckweed, grass, dredging mud (if the amount of mud is too much), leveling the bottom, filling all the holes along the pond bank.

Remove lime all over the pond bottom, to kill trash fish and pathogens, by evenly spreading 8-10 kg of lime powder for 100m2 of pond bottom. If in the pond in the previous crop, fish and shrimp are sick or the pond is acidic, the amount of lime will increase 2 times (from 15-20kg/100m2).

Dry the pond for about 3 days, fertilize by spreading evenly throughout the pond 30-40 kg of well-composted manure and 40-50 kg of green leaves (soft stem leaves to make green manure) for 100 m2. Green leaves are chopped and spread evenly throughout the pond bottom. Use buffalo to harrow the pond bottom 1-2 times to mix green manure and leaves into the mud and flatten the pond bottom.

Filter water into the pond about 0.5 m, soak the pond for 5-7 days, the pond water will be banana green (the color of plankton), filter the water into the pond to reach a depth of 1 m before releasing the fish. Filter the water with a net or a net to prevent bad fish and trash fish from entering the fish pond.

Treatment of fingerlings before stocking

Use fish to test the water: plug the stage or basket into the pond, drop 10-15 fingerlings in it. Monitoring fish from 20-30 minutes to see that the fish is working normally, if it is found that the fish is weak or dead, then the fish must be temporarily stopped to release the water that has been taken into the pond. Before releasing the fish back into the pond, the fish must also be used to test the water.

Bathing for fingerlings to prevent disease: When the fingerlings are transported back, before stocking, they should be bathed in salt water (NaCl) with a concentration of 3%. How to bathe: Use a basin containing 10 liters of clean water, dissolve 300g of table salt in water, use a fishing net to bathe for 10-15 minutes.

Avoid letting fish be “shocked” by the temperature difference between the pond water and the water containing the fish: when releasing fish into the pond, to ensure the safety of the fish, it is necessary to pay attention to balance the water temperature between the two environments, especially fingerlings are transported long distances during high temperature summers. Method: soak the fish bag in the pond for 5-10 minutes before releasing. Release the fish: open the bag tie, push half of the bag’s mouth into the water, put the water in the pond slowly into the bag, when the fish is healthy, swim against the current, release the fish into the pond. Pay attention to drop fish in the wind so that the fish disperse quickly into the pond.

Care and management

Feeding according to the principle of 4 determination (quantitative, qualitative, positioning, timing). The ration feeds 2-3% of the total fish in the pond. The ration decreased as the fish grew larger. Feed twice a day (morning and afternoon), when it is not raining, the water is rich in oxygen.

Carp when raised in high density of food and environmental conditions are not like in nature, so the resistance of fish is lower, more susceptible to diseases, especially digestive diseases. To help fish digest, absorb nutrients better, increase resistance, stimulate immunity, add BioBactil to the feed 3-5g/kg of feed once a day.

Periodically or when the weather is unfavorable, it is recommended to add vitamin C and dissolved ions to help fish enhance mineral exchange – C vitan with a dose of 1kg for 1500-2000m3 of water.

Check the dining floor, monitor and periodically check the weight of fish as well as control pathogens to change the amount of food and appropriate diet.

To keep the appropriate amount of water, check the pond banks and drains every day. Change the water periodically (weekly, monthly…) depending on the pollution level of the pond. Each time change 20-30% of the water in the pond. Increase the water level according to the growth of the fish. Observe the fish’s activities: floating head, swimming, eating power, … to promptly handle when there are abnormal signs. Protect fish from loss in flood season (repair pond banks, net fences, etc.).

Monitor the water color regularly to increase or decrease the amount of food, pay attention to the fluctuations of DO, pH, toxic gases… in the pond so that the fish are not shocked when suddenly changing the above factors. Use ZEO ramin to absorb toxic gases (if any), stabilize the environment and increase the solubility of oxygen in water, use 15-20kg every 2-3 days for 1000-2000m3 of water.

Harvest

Usually after about 6-8 months of culture, it can be harvested. It is possible to prune those that meet the standards of meat fish. 1 day before harvest must stop feeding. When harvesting, the water must be withdrawn. Statistics of yield by number of animals and weight to draw lessons from next year’s farming.
