Aanvullend advies

Divide the “Feed quantity per day” over at least two feeding moments per day.
Feed at least three different species of fish (herring, smelt, mackerel or capelin).
The supplements should be given according to the appropriate dosage that is mentioned on the labelling.
During the winter, the daily food intake increases and they should be fed accordingly.
Stimulate foraging behaviour by using ice cubes with frozen fish, large fish heads and feed balls stuffed with fish (read more about feed enrichment and foraging behaviour).
