Understanding Koi Fish Koi is part of a wide variety of carp species and belongs to the Cyprinid family. Koi Fish have been selectively bred for color, pattern, and scale type.

How to Start Hybrid Koi fish farming?

The good news is that it is much easier than you think. All you need to start hybrid koi fish farming is a good koi breeder and some pots.

The next step will be to hatch some eggs (you can buy them or start with your own). After hatching, the stage of fry will begin.

You can either let the young fry grow in their natural environment and market them or care for them yourself until the Fish reach 1 inch (2.5 cm) in length. After they come 1 inch (2.5 cm), it’s time to set up the fish ponds.

Classification of Koi Fish

The scientific name and classification of koi fish are listed below.

1. Scientific name

Cyprinus carpio Linnaeus, 1758

10. In Haryana, Kohi fish are raised in the rivers like Rohtas, Kurukshetra, Panipat, and Yamuna (shown above).

Pond Selection & Management

Hybrid Koi fish farming can be done on any pond. The size of the pond should be about 1/4 to 1/2 of the total area.

The pond should have high clarity and good lighting. You can also use a natural light source such as fluorescent lamps if possible.

It would help if you started with some small ponds to observe how your koi fish react to them and observe the eggs being hatched from them.

Using Lime & Fertilizer

Along with the mixtures of water and fish food, you should use a variety containing calcium sulfate and phosphate to control algae and provide some minerals (phosphorus, potassium, iron, etc…) to the pond.

You can also use mixtures of lime, cottonseed meal, and fish fertilizer. The best way to know that your Fish are healthy is by checking the color of their fins when you look at them from different sides.

The pH level in the water should be between 5.5 – 6.5. You should check the water quality every day and feed your koi fish with different nutritional supplements as per their needs from time to time.

Feed Management

It is essential to know the diet of your Fish. Try to provide them with different types of food from many various sources. In the beginning, you can feed them with pellets and flakes containing protein, vitamins, and fats.

You should also add supplements to your diet to get adequate sunlight and water. You can provide them with pellets and flakes containing dry organic materials such as wheat flour, rice bran oil, etc.

Rough Feed Management

You should check the ratio in a day and feed your Fish as per their diet. Your fish food should be at least half of the total water volume (2.5 gallons/10 liters).

If you see that your koi fish is getting bored with the food, you can add some live or frozen food to make it more interesting. It is also good to provide them with spirulina flakes, blue-green algae, etc.

Commercial Feed Feed Applying Rate

It would be best if you feed your koi fish once a day. You should always check their diet at least twice a day and remove any expired food.

You should not be feeding them the same food most of the time. It is good to provide them with different types of water plants and seeds to keep them healthy and happy.

Feeding Guidelines

You can supplement your koi feed with blood worms, pieces of fish meat, fish scraps, etc…

For 1 kg/2.2 pound of koi fish food, you can use:

1. 100g/3.5oz blood worms

2. 100g/3.5oz fish scraps

3. 100g/3.5oz protein powder

4. 100g/3.5oz wheat flour

5. 200g/7oz bran-based pellets (non-medicated).

6. 200g/7oz soybean flakes or oil cakes (non-medicated). 

7. 200g/7oz rice bran oil or organic compost.

8. 200g/7oz wheat flour and bran oils.

9. 200-300g/7-10 oz fish meal (non-medicated).

Koi Fish Growth Stages

There are four stages in hybrid koi fish farming:  eggs, fry, fingerlings, and adults.  Please note that the eggs can be hatched naturally or artificially, depending on the breeder’s experience or purpose.

Breeding, Caring & Other Management

You should feed your koi fish twice a day. You should provide them with the same amount of water in a day and about 100-200 gallons per acre. The temperature in a pond should be between 15-18 degrees Celsius.

If you see that your koi fish is blind, deaf, or has slime on their bodies, you can immediately take them to a veterinarian.

Harvesting & Marketing

Koi Fish are usually marketed as fingerlings at the size of 3-4 inches. Koi Matsuri is a Japanese festival celebrated around November when koi prices go up due to a demand for Fish in seasonal cuisine and food preparation.

The price of Koi fish is determined by the color, pattern, and quality of its scales. Koi Fish are available in various colors, with white being the most expensive.
