FIFO measures the amounts of fishmeal and fish oil used to produce one weight equivalent of farmed fish back to wild fish weight equivalents, while the forage fish dependency ratio (FFDR) is the amount of wild-caught fish used to produce the amounts of fishmeal and fish oil required.
Skretting recognises difference between FIFO and FFDR and how they are used by different stakeholders in different situations. That said, with a finite supply of fishmeal and fish oil, further growth of the aquaculture feed production will automatically require even further reduction of the inclusion of marine resources in the diets.
“We believe it is more important to communicate to the media and the consumers the need for sustainable sourced marine ingredients for fish feed, as applicable for any other ingredient used in aquafeeds. These should be expected to be subjected to the same level of scrutiny applied to marine-source materials whilst also of stressing the need of reduction of FIFO within the aquaculture sector.” – Trygve Berg Lea, Skretting Sustainability Manager.
