This study was conducted to determine the effect of storage conditions on the quality of feed and the aftermath effect of feeding fish with such feeds. Three commercial diets used for this study included Coppens®, Multifeed® and Vital feed®. Feed was stored either by opening the bag to the atmosphere (WO), the bag opened with neck tied using a rubber ring to prevent exposure to the atmosphere (OT) or sealed (SC) until the start of the feeding trials. The feed was stored under these conditions for six months. Nutrient analyses revealed significant changes in feeds held under the WO condition when compared with other storage conditions. Nutritive changes also varied with commercial feed type. Mould infestation of the feed was noticeable more in the WO condition of storage compared to the SC condition. After feeding
