Our advice is to feed from 5°C water temperature, with an appropriate amount of feed. If the water gets colder than 8 °C, the feeding behaviour of the fish decreases significantly. Around 5 °C, metabolism will also have slowed down so much and the action of digestive enzymes will have decreased so much that the food in the intestines is no longer digested. Eating feed will then be counterproductive. Calculate the daily quantity of koi feed using the total weight of koi and water temperature, according to the table below. Example calculation: If the water temperature is 8 °C and you have 10 kg of koi in your pond, the daily quantity of koi food is:10.0 kg koi x 0.5 % = 10,000 grams /100 x 0.5 = 50 grams of koi food.
