Kvantitativ testing av mineraler i nyre for påvisning av nefrokalsinose i fisk

Offentlig prosjektsammendrag

STIM has established a unique assay that measures the mineralized calcium content of kidney tissue, shown to be increased in salmon and trout in a pathological process called nephrocalcinosis. Nephrocalcinosis damages kidney function in fish due to the accumulation of mineralized calcium salts within the kidney tubules and supporting tissues. As recognized by the Norwegian Veterinary Institute in its Fish Health Report published in 2024, fish nephrocalcinosis is ranked as the second most important health challenge in hatcheries and is a significant animal welfare problem. Despite its importance, quantitative assay measurements of nephrocalcinosis in fish have been either expensive or not widely available. STIM plans to use this new assay method in combination with its existing fish health services and commercial products for salmon hatcheries to provide further improvements in fish feeds, hatchery practices and smoltification methods.
