Feeding by growth stage

General starting ranges, as a share of the fish's body weight each day. Adjust to appetite, water temperature and oxygen, and ask your advisor for your own pond.

Floating and sinking feed together

Common carp forage on the bottom and do best on a sinking feed. They will take floating pellets too, but in a polyculture pond the surface feeders get there first, so make sure enough sinking feed reaches the carp.

Good practice

  • Make a sinking feed the main diet.
  • Feed in the cooler hours, early morning and evening.
  • Reduce the ration in winter, when the fish slow down.
  • Keep the pond bottom in good condition so the fish keep feeding on it.

Mistakes to avoid

  • Relying only on floating feed in a polyculture pond.
  • Feeding the summer ration in cold months.
  • Neglecting the pond bottom, where carp feed.
  • Using a low-protein feed for the whole culture period.
  • Not grading, so a few large fish take most of the feed.
