A new research project to formulate low-impact, money-saving fish feed has been formed by industry players.
Fish need proteins for growth, but optimum growth of fish cannot be obtained by simply adding more proteins to the feed. The fish must be able to digest the proteins and even small differences in the composition and structure of the proteins have considerable effects on their digestibility. If the digestibility of the proteins is optimal the fish growth will improve and the load of nitrogen in the fish faeces will be reduced, leading to a reduction of the environmental impact on the surroundings.
