Aquaculture is one of the fastest growing animal production activities in the world and it plays a vital role in many countries by providing economic, social and nutritional opportunities. However, the production of several culture species heavily depend on feed produced from resources of wild fisheries, namely fish meal and oil, that aquafeed manufacturing is a major contributor to several of the impact categories. In reality, the increased focus on growing few high value culture species at large quantities will accelerate the demand for fish meal and oil, a concern that is threatening the global capture of fish currently in decline due to overfishing and environmental changes. Therefore, continued growth of aquaculture production dictates that substitutes must be utilised without compromising fish health and product quality. In response, several investigators have successfully observed that partial or complete substitution of fishmeal by alternate protein sources, such as soybean meal and rapeseed meal, is possible.
