Background and research interests:
Feed remains the biggest cost and a foreseen impediment to sustainable aquaculture development worldwide. Raw material quality determines feeds palatability, digestibility, nutrient utilization and subsequent fish growth. Thus, my research explores lipid oxidation in raw materials and fish feeds as a quality aspect that can impair fish farming in Uganda. The use of natural antioxidants to control lipid oxidation in aqua-feeds and their effects on fish growth are examined. Insights about the possibility of replacing fishmeal with the less utilized protein sources in tilapia diets are given. I conclude by enumerating how aquaculture growth studies should be designed to achieve reliable results at minimum cost. Overall this work provides useful information to aquaculture scientists and managers.
