Pond Selection & Management

It will be better if the selected pond is in open area where adequate sunshine is available. Clean the bush around the pond shore. Cut the branches if there are any big trees in the shore, and ensure at least 8 hours sunlight every day.

Especially smaller sized pond is very suitable for Thai koi fish farming business. The perfect size of the pond is 20-30 cent (8500 to 13000 square feet).

The main advantage of small pond is easy of maintain. Because, the smaller sized ponds are easily maintained. Ideal depth of the pond is 5-6 feet.

For preparing the pond, remove water from it and let it dry. Remove the excessive clay from the pond, because excessive clay creates harmful gases.

You can use some sand for minimizing the amount of clay. Sand keeps the water clean and environment of the pond fresh.

Using Lime & Fertilizer

After making the pond dry, you have to prepare it for koi fish farming by using both chemical and organic fertilizers.

Using lime is very important. Use lime at the rate of 100 kg per acre. Use 500 kg dung per acre after applying lime. Fill the pond with water, after using organic fertilizers.

And then spray 20 kg urea and 20 kg TSP (triple super phosphate) per acre by mixing with water. You can also apply directly instead of spraying with water.

You can stock the minnow of Thai koi after 5-7 days of applying organic and chemical fertilizers.

If it’s not possible for you to make the pond dry, then ensure there are no harmful animals or cannibalistic fish species available in the pond.

Then apply 100 kg lime per acre. And after 3-5 days of that use, apply 500 kg dung, 20 kg urea and 20 kg TSP per acre.

And you can stock minnow 5-7 days after applying the fertilizer. Water of the pond will become slightly green, after 5-7 days of applying fertilizers.

In this system, you can use snail or oyster flesh, toad minnow, tripe or fishmeal (not regularly), rice bran, mustardcake etc.

Using at least one from the above mentioned feed ingredients and using others occasionally can bring good result.

High quality rough feed can be made for Thai koi fish by mixing 25% fishmeal, 30% rice bran, 25% mustard or coconut cake, 20% roughage together.

Commercial Feed

For regular and commercial koi fish farming, you have to provide them sufficient amount of high quality pelleted feed to get maximum production.
