How much to feed?

This morning a Mr Mohan (did not ask his full name) bought 2 koi to bring his koi collection to 9 as two died after a recent rain. He also asked about how much to feed his koi. Here is our recommendation - 3% of koi food for the total weight of koi in his pond. As a guide, a 12-inch koi (or 3 pcs of 8-inch koi) weighs about 600 gm, so at 3%, the food for this one koi is 18 gm per day. How much is 18 gm? Again as a guide if you use an adult bare hand to grab some koi food and hold them at half- grip - it's about 18 gm. Have fun feeding your koi!
