Maximizing the sustainability of our supply chain and raw materials 

By improving our supply chain, we tackle these primary challenges of the aquaculture ecosystem:

Reducing the Forage Fish Dependency Ratio (FFDR) 

The FFDR evaluates aquaculture’s direct dependency on a pelagic fishery (e.g., anchoveta) or a fishery where the catch is directly reduced (such as krill).  

Two factors influence the FFDR: 

  • the inclusion of forage fish versus the total marine ingredient in the formula: the lower the inclusion of forage fish, the lower the FFDR 
  • Feed Conversion Rate (FCR): the lower the FCR (feed efficiency), the lower the FFDR 

According to Aquaculture Stewardship Council (ASC) standards for farms, “Fishmeal and fish oil derived from fisheries’ by-products (e.g., trimmings and offal) should not be included in the calculation.” 

Because 100% of our production comes from co-product raw materials, our products help reduce FFRD in fish and shrimp feed formulas. 

Ensuring responsible supply  

  • Vendors commit to respecting the Symrise Responsible Sourcing Policy and Supplier Code of Conduct

  • We conduct due diligence throughout our supply chain to identify and mitigate risks to human rights and the environment

Giving our guarantee of sustainable supply 

  • Evaluation of fish resources for each new supplier listing 

  • Evaluation of suppliers’ level of certification 

  • Our ambition for the coming years: to reach 100% of co-product from aquaculture or certified wild catch
