\n

Quick answer:<\/strong> Good fish meal combines high protein with freshness. Check crude protein, TVB-N (a freshness indicator, lower is better), histamine, fat oxidation, salt and sand (acid-insoluble ash). Store bags dry, ventilated and off the floor, and make sure the meal contains an antioxidant, because fish oil oxidises and can self-heat in hot climates.<\/p>\n
