Our impact

Feed Conversion Ratio

Fish has a low feed conversion ratio compared to other animal proteins. We are continuously working to reduce our feed conversion ratio further.

Feed conversion ratio (FCR) measures the productivity of different protein production systems. A lower FCR represents a more efficient use of feed resources.

Efforts to improve our Feed Conversion Ratio (FCR)

Excess feed is a waste of resources, may pose a local environmental challenge and is costly. Avoiding excess feeding is important to reduce the FCR further. We are working to specialize feeding operations, amongst other things by centralizing feeding in one or a few operational centers in each region. More digital tools and cameras applied in the pens to help assess when the salmon is full, reduces excess feed.

We are also measuring the economic Feed Conversion Ratio (eFCR), which adds mortality to the measurement. The eFCR describes the amount of feed required to produce one kilo of farmed salmon. It is calculated as the total weight of feed divided by net production (harvested weight).

The biological feed conversion ratio describes the amount of feed required to produce one kilo of farmed salmon. It is calculated as the total weight of feed divided by gross growth (incl. mortality). The ratio is an indicator of feed efficiency, reflecting how effective a feed strategy can be. The bFCR ratio is impacted by the ability of the fish to utilize the nutrients in the feed for growth. The ratio is also impacted by over- or underfeeding, causing feed spill or reduced growth, respectively. The biological challenges we experienced in 2020 impacted fish appetite negatively and as such the bFCR increased. The measures we are implementing to tackle biological challenges will consequently reduce bFCR.
