What makes top segment Marks Koi Food so healthy for koi?

We are not sitting still with the development of our koi food. With the steep price increases of raw materials worldwide, it is good that we cooperate with several suppliers from all over the world and several factories in Europe. This is how we keep quality high and prices low. In our search for raw materials by the end of 2022, we improved the recipe as follows:

  • The concentration of vitamins has been increased, allowing your koi to be even more resistant to infectious diseases.
  • The protein content has been increased from 40% to 42%, while the utilisability of protein has increased from 70% to 80%! We have achieved this through increased use of Tripple 9 fishmeal, pre-digested fishmeal and the protein-rich squid meal. These proteins benefit length and body growth. Furthermore, koi find a high protein content irresistibly tasty!
  • The fat percentage has been reduced to 10%, further reducing the risk of fattening.

Furthermore, Marks Koi food is characterized by:

  • Shield: this addition stimulates the mucous membrane so that parasites are repelled by the fish’s mucous membrane.
  • Means of binding feces. The feces are encapsulated so that they do not dissolve in the water, but can be sucked up in their entirety by the filter. This reduces algae growth and thus ensures beautifully clear water.

What makes our food even better?

Koi are my great love and have built myself a Japanese garden with a heated koi pond. During my travels in Japan, I buy high-quality koi aged 1 or 2 years, which I let grow on in my pond. I feed my koi several times a day. I can experience the positive effect of my koi food on a daily basis. When I put 1-year-old koi (40 to 45 cm in size) in my pond in April, most of them grow to a length of 56 to 65 cm in 6 months! The colors are intense and the scales shine beautifully. The fish are lively and resistant to fish diseases. It is a daily pleasure to see the koi eagerly eating floating and sinking Marks Koi food.
