Various methods such as sun-drying, smoking and refrigeration as currently used to prevent such loses are either costly, unavailable to the intended users or ineffective. In addition, the anti-oxidants available in the market to mitigate loses occasioned by oxidation to the fish are mainly artificial and yet to be optimized for Oreochromis niloticus. This study quantified the interactive effects between the storage temperature and ambient humidity and the effectiveness of Citric acid, Vitamin E (tocopherol), Rosemarinic acid, Propyl gallate and Vitamin C in arresting fish tissue oxidation. This study observed the fish, starts to rot from the head and this spoilage could only be controlled by temperature at low to medium humidity (< ca. 35 %) values. At high humidity, ca. 65%, the rate of spoilage was purely humidity controlled. The effectiveness order of Vitamin E & Copyright@ International Science Community Association
