THE PURPOSE OF DIFFERENT NUTRIENTS
The food must contain a well-balanced composition of nutrients, vitamins, minerals and trace elements to provide nutrition according to the natural requirements of the individual fish.

Carbohydrates and fats
These are the most important energy sources in the food. However, if an over supply occurs, especially fat, this can lead to organ damages. Therefore good food should have less than 6%, rearing young fish it can contain up to 8%.

Protein
Consists of long chains of connected amino acids. The fish absorbs the amino acids for building up muscles. Rich in protein is real “power nutrition” for every fish. Animal protein is faster and easer to digest than vegetable protein.

Trace Elements
They are regarded as the “tools” of the organism. Trace Elements as the name implies are only required in very small amounts.

Minerals
For example calcium are important for building the skeleton and therefore the healthy growth of fish.

Ballast Substances
While having no direct nutritional value yet they have a very important part to play as they act as an effective defence against inertia of the bowels, which will otherwise cause complications.

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.
