ORBIT differs from current feed for young fish in many areas. Improved protein digestibility reduces nitrogen emissions into the aquatic environment.
Our experiments show an 11% reduction in nitrogen emissions in the form of ammonia via the fishes' gills (see figure). In theoretical terms, this means that existing biofilter capacity can handle an increase in feeding of around 10% when ORBIT is used.
Comprehensive research programme
It all started in Denmark with the farming of freshwater trout, where the key thing is good growth and extensive production without increasing emissions to other freshwater recipients. The concept has been further developed and is now thoroughly documented for salmon in the North Sea and Americas. ORBIT is supported by a comprehensive research programme with experiments that have been carried out over the last 3 years. All these research results have now been implemented in ORBIT.
A range of raw material combinations have been tested to find the optimum raw materials for the desired effect on faecal structure (see figure).
Provides equally good growth as the best standard feed for young fish
Provides a lower FCR than the best standard feed for young fish
Provides the best water quality
Provides fewer nitrogen emissions and organic matter
Reduces biofilter load
Provides better intestinal health
