The role of aquaculture in the supply of fish in the future is undeniable . The consumption of fish products has several benefits for human health due to the quality of its protein, fatty acid profiles and supply of minerals and vitamins. Aquaculture is the fastest growing animal industry but because it uses natural resources, it causes environmental changes. Fish farming has evolved throughout many decades but the search for environmentally friendly and sustainable solutions are one of the current concerns. There are several paths towards sustainability either by a) feed formulation , which is important in terms of fish meal replacement and optimisation according to fish nutritional requirements, b) the adoption of environmentally friendly farming such as Integrated Multitrophic Aquaculture (IMTA) and c) increasing fish welfare and consequently reduce stress. The three paths have an i mportant impact on both fish quality and environment, with the first path being the centre of much research and the latter still giving its first steps. This presentation will focus on the development of feed formulation, the adaptation of already existent models to embrace IMTA, leading to better fish quality and better environment and explain why we should pay more attention to fish welfare.
