Live Food: An Essential For Koi Fry?

In issue 7 (October 2021) of Koi Talk magazine we published an article by Sam Norley, General Manager at Cuttlebrook Koi Farm focussing on feeding live food to Koi fry.

The purpose of feeding live food to Koi fry is to match as closely as possible the food the larvae will be eating in their natural environment. This involves culturing billions of microscopic algae (phytoplankton) to feed millions of zooplankton which are subsequently fed to thousands of fish larvae. This is a naturally occurring relationship that keeps populations healthy and in balance, known as a food web.

If you’ve not yet seen the article, don’t miss out! Issue 7 is available to purchase in the back issues section of our website.
