Hercules Opti feed has been developed for the final stage of salmon farming to ensure the optimal amount of the healthy EPA and DHA fatty acids naturally found in oily fish.
Sustainable farming of healthy salmon
Salmon feeding can made more plant-based without reducing the nutritional values of the fish. With this invention, both the profitability and ecological sustainability of salmon farming will improve as the use of expensive fish oil produced from wild fish can be significantly reduced. Raisioagro has been a key partner for the Finnish Game and Fisheries Research Institute in the development process of the new fish feed.
The concept of Hercules OPTI combines new invention and environmental issues
Hercules Opti belongs to the Raisioagro's environmentally friendly Hercules product line. Hercules was launched in 2009 and it was the first in the world to use phytase enzyme in feed for big rainbow trout. Due to the enzyme, the phosphorus load of waterways was reduced by 26%. Raisioagro has been a key partner for the Finnish Game and Fisheries Research Institute in the development process of the new fish feed.
Vegetable oil replacing the fish oil from wild fish
In recent years, vegetable oils have been increasingly used in salmon feeding globally, since the production chain and profitability of fish farming can be significantly improved with the use of more affordable vegetable oil instead of much more expensive fish oil. High price of fish oil is a sign of the volume shortage in relation to demand.
Rainbow trout and whitefish farmed in Finland has been added on the WWF's green list
With higher use of vegetable oil, the amount of healthy fatty acids in salmon will decrease because the fish mainly gets these fatty acids from fish oil. Raisioagro uses rapeseed oil to replace fish oil. With Hercules Opti, it is possible to have the levels of EPA and DHA fatty acids in salmon back on the levels recommended in dietary guidelines as the feed for the final stage of farming includes a high amount of fish oil.
Thanks to Hercules Opti, Finnish rainbow trout remains an important source of EPA and DHA fatty acids. Rainbow trout fed Raisioagro's Opti contain the amount of fatty acids, good for the heart and blood vessels, recommended by The National Institute for Health and Welfare (200 grams of fish per week) and lowers the environmental impact of fish farming.
Several Raisio’s fish feed innovations have reduced the environmental impacts of fish farming. WWF Finland added Finnish farmed rainbow trout on the green list of its Seafood Guide in 2014 and Finnish farmed whitefish in 2016.
