Advances in culture techniques and introduction of new species have contributed to the rapid growth of the aquaculture industry. Indeed this rapid growth has led to the awareness that fishmeal and fish oil are reaching their maximum exploitation levels are key factors driving research focus towards development of new aquafeeds that ensure fish are of highest quality whilst reducing the use of these limited commodities. It is widely accepted that nutrition has major health implications in fish and so the interaction of amino acids, vitamins and minerals are required in cell division and the synthesis of important proteins by immune cells. Thus it is important that dietary formulations meet known nutritional requirements, in a cost effective manner because aquafeeds often represent the largest component of production costs in aquaculture and ornamental industry. Subsequently the main focus of the PhD was to determine the effect of feeding alternative protein sources on fish health status and growth performance, for potential use in a commercial aquafeed formulation. My PhD has provided preliminary data to confirm that some of the tested novel protein sources gave rise to increased health status and growth performance of C. carpio (a model ornamental species), when compared to fishmeal. This has provided a platform for further work investigating the use of novel protein sources on the humoral and cellular immunological response of cyprinids at the intestinal and systemic level Show less
