NEWS FEED & ADDITIVE MAGAZINE November 2024 83 Melanin spots in Atlantic salmon fillets are a growing concern in the salmon farming industry, leading to product downgrades, reduced yields, and increased processing costs. According to Aker BioMarine, QRILL Aqua, a krill-based ingredient rich in essential fatty acids, significantly reduced these dark spots – improving fillet quality and helping farmers maximize returns. Melanin spots in Atlantic salmon fillets, also known as melanosis, are a common quality issue affecting up to 30% of fish in some regions, the company explains. These spots are the result of the fish’s immune response to inflammation caused by stress or tissue damage. Research shows that including Antarctic krill-based QRILL Aqua in the feed, with its high levels of omega-3 fatty acids, can effectively prevent accumulation of melanin pigments and improve fillet quality. When the fish is subject to injury or stress, such as hypoxia or trauma, dark melanin pigments appear on the fillet, according to the press release. Dealing with these spots requires the removal of affected areas, which increases labor costs and at times can lead to the complete discarding of fillets. This translates to economic losses for farmers. In Norway alone, as much as 20% of harvested salmon is impacted, while in Chile, melanin spots are responsible for nearly 30% of downgrades, according to Aquabench.
