About this file
The document contains detailed food specifications for trout and salmon aquaculture feed, outlining precise nutritional and physical requirements for different pellet sizes. The specifications provide comprehensive details for feed manufacturers, including minimum protein and lipid percentages, maximum ash and fiber content, moisture levels, and specific requirements like probiotic/immunostimulant inclusion and astaxanthin content.
For trout feed, the specifications cover three size categories (Starter, #1, #2) ranging from 1.5 to 6.5 mm, with pellet sizes strictly defined between 0.6-1.2 mm and tolerances of +/- 0.5mm. Salmon feed specifications are even more granular, ranging from mash (0.25-0.4 mm) to 4.0 mm pellets, with varying protein (45-53%), lipid (18-24%), and energy content. Both specifications require pellets to maintain specific floating characteristics, with trout feed mandating slow-sinking properties and salmon feed including beta-glucans as an additional nutritional component.
