Here are the main ingredients typically found in koi fish feed: wheat flour, soybean meal, cornmeal, fish meal, bran, yeast, and fish oil. Wheat flour is the most abundant component, primarily providing energy to the fish to maintain vital functions and promote growth. Soybean meal supplies protein and amino acids to aid in the synthesis of essential body substances. Cornmeal offers carbohydrates and fiber to support life functions. Fish meal provides highquality protein and fat to enhance the fish's resistance. Bran supplies fat and undigested carbohydrates to aid in digestion and growth. Yeast offers a variety of vitamins and trace elements, contributing to the fish's immunity. Fish oil provides unsaturated fatty acids and vitamins to strengthen the koi's resistance.

The common ratio of these ingredients in koi feed is approximately 30% wheat flour, 20% fish meal, 30% soybean meal, 10% cornmeal, 6% bran, 2% fish oil, and 2% yeast. However, different types of koi feed, such as flavored or premixed varieties, may have varying ratios.
