Pond Selection and Management
It would be better if the pond situated in open air and sunshine place. Clean the bush of pond shore. Cut the branches if there any big trees in the shore and ensure 8 hours sunlight every day. Especially small pond is very suitable for thai koi fish farming. The perfect size of the pond is 20-30 shotok. Small sized pond are easily maintained. Ideal depth of the pond is 5-6 feet. Firstly remove the water from the pond and make it dry. Remove the excessive clay from the pond because excessive clay creates harmful gas. Use some sand for minimizing the amount of clay. Sand keeps the water clean and environment of the pond fresh.

Using Lime and Fertilizer
After making the pond dry use lime at the rate of 1 kg per shotok. Use 5kg dung per shotok after applying lime. After using organic fertilizer enter water to the pond. And after that spray 200g urea and 200g TSP per shotok by mixing with water. Relese the minnow of thai koi after 5-7 days of applying organic and chemical fertilizer. If it become not possible to make the pond dry then make sure that the pond is free from all types of cannibalistic fish and other animal. For this reason using rotenon is very effective. After removing aquatic weeds and cannibalistic fishes from the pond use 1kg lime per shotok and after 3-5 days of that use 5kg dung, 200g urea and 200g TSP per shotok. 5-7 days after applying the fertilizer to the pond release minnow when the color of the water will be slightly green.

Feed Management
Thai koi is a very fast growing fish. For this reason ensure the sufficient supply of feed. Feed management can be done in two ways which are described below.

Rough Feed Management
For desired growth of koi fish the farmer must have the efficiency of rough feed management. This is the primary feed management system and mainly for poor fish farmer. In this system snail or oyster flesh, toad minnow, tripe or fishmeal (not regularly), rice dust, cake etc. can be used. Using at least one among the above mentioned feed and using other occasionally can bring good result. High quality rough feed can be made for thai fish by mixing 25% fishmeal, 30 rice dust, 25% cake, 20% roughage together.

Commercial Feed
For regular and commercial koi fish farming the farmer have to ensure sufficient supply of high quality pellet feed to get expected production. This pellet feed should contain 30-35% protein.
