• Increased growth
  • Reduced feed conversion ratio
  • Reduced emissions of phosphorus and zinc

At Skretting, we believe that feed raw materials are key to good growth and fish health. The fish do not need specific raw materials, but rather the nutrients in them. Increased use of new feed raw materials and optimising existing ones help ensure sustainable growth in the aquaculture industry.

Nutra Terra is our innovation in growth feed for juvenile fish and has been developed through careful testing of various raw materials and feed formulations. With Nutra Terra, we have reduced the use of limited raw materials compared to conventional hatchery feed. The enzyme phytase is added to the feed, making phosphorus and zinc more accessible to the fish. This enables us to reduce the total amount of phosphorus and zinc in the feed.

Trial results show better growth and reduced feed conversion ratio. At the same time, we see reduced emissions of phosphorus and zink in faeces.

Nutra Terra – a better choice for the fish and the environment.


Nutra Terra is currently available in Norway.

Symbol for better performance with Nutra Terra
Better performance

Validation trials at our research station at Lerang, Norway show that fish fed with Nutra Terra gain a higher weight and lower feed  conversion ratio than the control group.

Reduced emissions

To fulfil feed performance needs while reducing emissions, the enzyme phytase -making phosphorus and zinc more accessible - has been added to Nutra Terra. Trials show a reduced amount of phosphorus and zinc in faeces.

Resource utilisation with Nutra Terra
Better resource utilisation

A lower feed conversion ratio means less kilograms of feed per kilo of fish produced. This helps to reduce pressure on vulnerable feed raw materials. By using insect meal and phytase, we are able to utilise the raw materials in a better way.
