Abstract
The current trend in aquaculture is moving towards the more intensive production of carnivorous fish Carnivorous fish have a dietary protein demand between 40% and 55%, higher than that of the herbivorous or omnivorous fish species with 25%-35%, (National Research Council, 2011). Considering this trend, and the predicted further increase in global aquaculture production (World Bank, 2013), an even higher demand on fishmeal for aquafeed can be expected. Despite the strict reduction of fishmeal in aquafeed over the past years, the change to full supplementation with alternative protein sources has shown to lead to reduced growth performance and health issues in fish
