According to the press release of Skretting, the researchers Wolfgang Koppe and Ramon Fontanillas has made remarkable contribution to the scientific article “Dietary histidine supplementation prevents cataract development in adultAtlantic salmon, Salmo salar L., in seawater” which is published in British Journal of Nutrition.
The main purpose of the study was to investigate the cataract preventive effect of dietary histidine regimes in adult Atlantic salmon in seawater, both through manipulating the dietary histidine level and feeding period. Three fishmeal and fish oil-based extruded diets, differing only in histidine content (low, high and medium) were fed to duplicate net pens in seawater.
The study shows the risk for cataract development for adult Atlantic salmon, 1 year after the transfer of salmon smolts from freshwater to seawater, which to a major extent can be prevented by histidine supplementation just before and during the early phase of cataract development.
