How Much Wild Fish is used in Skretting Feeds?
The use of fishmeal and fish oil in aquafeeds is one of, if not the most important issue for the feed industry. This is because feeds traditionally contained high levels of fishmeal and fish oil, sourced from finite supplies of wild-caught forage fish.
Forage fish can be classified as wild-caught, small bony fish, not usually desired by humans for eating, but are commonly converted into fishmeal and fish oil ingredients and used in other industries.
The main forage fish species that are caught for use as fishmeal and fish oil in Skretting Australia feeds are Anchovy from Peru. These fisheries are responsible for supplying a large proportion of the world’s supply of fishmeal and fish oil.
The Fish Forage Dependency Ratio (FFDR) is a calculation used in global certification standards such as the Aquaculture Stewardship Council (ASC) Salmon Standard. The ratios calculate the dependency on forage fisheries through an assessment of the quantity of live fish from small pelagic fisheries required to produce the amount of fishmeal and fish oil needed to produce a unit of farmed salmon. The calculations are used to satisfy limits stipulated in Criterion 4.2 ‘Use of wild fish for feed’ of the ASC salmon standard v.1.1. The graphics below show the FFDR values for Skretting Australia feeds from 2013-2016.
The figure above displays Skretting Australia's FFDR values for fishmeal between 2013-2016.

Skretting has achieved lower FFDR values through more efficient use of their marine raw materials and the identification of alternative raw materials to deliver optimal nutrional support for farmed fish.
