Application of laboratory methods for understanding fish responses to black soldier fly (Hermetia illucens) based diets
Zarantoniello, Matteo; Randazzo, Basilio; Secci, Giulia; Notarstefano, Valentina; Giorgini, Elisabetta; Lock, Erik Jan Robert; Parisi, Giuliana; Olivotto, Ike (Journal article; Peer reviewed, 2022)A major challenge for development of sustainable aquafeeds is its dependence on fish meal and fish oil. Replacement with more sustainable, nutritious and safe ingredients is now a priority. Over the last years, among several ... -
Assessing amino acid solubility of black soldier fly larvae meal in Atlantic salmon (Salmo salar) in vivo and in vitro
Radhakrishnan, Gopika; Silva, Marta Sofia; Lock, Erik Jan Robert; Belghit, Ikram; Philip, Antony Jesu Prabhu (Journal article; Peer reviewed, 2022)In vitro and in vivo methods were used to evaluate amino acids solubility of black soldier fly (BSF) larvae meal and two experimental diets (reference and test diets) for Atlantic salmon. The current study used in vitro ... -
Assessing mineral availability in fish feeds using complementary methods demonstrated with the example of zinc in atlantic salmon
Silva, Marta Sofia; Stewart, Thea; Amlund, Heidi; Sloth, Jens Jørgen; Araujo, Pedro; Lock, Erik Jan Robert; Hogstrand, Christer; Ørnsrud, Robin; Waagbø, Rune; Prabhu, P. Antony Jesu (Journal article; Peer reviewed, 2021)Assessing the availability of dietary micro-minerals is a major challenge in mineral nutrition of fish species. The present article aims to describe a systematic approach combining different methodologies to assess the ... -
Blue mussel (Mytilus edulis) silage, a possible low trophic marine protein source for Atlantic salmon (Salmo salar L.)
Sartipiyarahmadi, Sahar; Philip, Antony Jesu Prabhu; Forshei, Aksel N.; Sveier, Harald; Steinsund, Silje; Kleppe, Malin; Lock, Erik Jan Robert; Madaro, Angelico; Hansen, Tom Johnny; Strand, Øivind; Wiech, Martin; Jakobsen, Jan Vidar; Remø, Sofie C. (Journal article; Peer reviewed, 2024)Blue mussel (Mytilus edulis) could be a promising marine protein source in fish feeds and is of great interest since it can be cultivated along the Norwegian coastline. However, the use of blue mussels in feeds is dependent ... -
Dietary zinc, selenium and water temperature during early seawater phase influences the development of vertebral deformities and cataract in adult Atlantic salmon
Philip, Antony Jesu Prabhu; Fjelldal, Per Gunnar; Remø, Sofie C.; Silva, Marta Sofia; Holme, May-Helen; Lock, Erik Jan Robert; Waagbø, Rune (Journal article; Peer reviewed, 2023)The impact of dietary trace minerals (TM; zinc and selenium) and water temperature during early seawater phase on the development of vertebral deformities and cataracts in adult Atlantic salmon was studied. Two experimental ... -
Evaluation of black soldier fly larvae meal as a functional feed ingredient in Atlantic salmon (Salmo salar) under farm-like conditions
Radhakrishnan, Gopika; Liland, Nina Sylvia; Koch, Marianne Wethe; Lock, Erik Jan Robert; Philip, Antony Jesu Prabhu; Belghit, Ikram (Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) were fed diets containing black soldier fly larvae (BSFL) meal at two inclusion levels for 13 months in open sea-cages. BSFL meal replaced plant-based ingredients and dietary insect meal ... -
Growth Performance, Nutrient Digestibility, and Retention in Atlantic Salmon, Salmo salar L., Fed Diets with Fermented Sugar Kelp, Saccharina latissima
Sartipiyarahmadi, Sahar; Philip, Antony Jesu Prabhu; Sveier, Harald; Steinsund, Silje; Lock, Erik Jan Robert; Madaro, Angelico; Hansen, Tom Johnny; Wiech, Martin; Strand, Øivind; Jakobsen, Jan Vidar; Van Der Heide, Marleen E.; Nørgaard, Jan Værum; Remø, Sofie C. (Journal article; Peer reviewed, 2023)Using low trophic marine resources such as sugar kelp (Saccharina latissimi) is of great interest to increase the circular food production in the ocean. Sugar kelp does, however, contain high levels of carbohydrates and ... -
In vitro assessment of protein digestibility and mineral solubility of black soldier fly larvae meals for monogastric animals
Silva, Marta Sofia; Matos, Rita; Araujo, Pedro; Lock, Erik Jan Robert; Radhakrishnan, Gopika; Prabhu, P. Antony Jesu; Belghit, Ikram (Journal article; Peer reviewed, 2022)Animal farming is a fast-growing sector which demands a large supply of feed materials and the search for novel feed ingredients with a smaller impact on the global environment has been intensified. However, before the ... -
