Koi Food Digestion Explained
In Koi carp, food is efficiently broken down into what is advantageous and what isn't. Nutritious goodness is digested and absorbed. Anything that isn't useful is expelled through its vent (anus).
This mechanical and physical process is aided by numerous food receptors that are highly sensitive to the presence of food. Koi are equipped with extremely good eye sight, a fantastic sense of smell and excellent hearing.
These highly tuned senses help the Koi to easily discern if they are about to receive a meal. You may have noticed that Koi appear to be excited and rise to the surface when they see a human presence, near the pond. They believe they are about to be fed.
