Sustainable development of European fish farming is dependent on the availability, environmental sustainability of feeds relying less and less on capture fisheries derived fishmeal and fish oil. The European aquaculture industry has made a determined shift towards the use of feeds based on alternative ingredients which continue to ensure the health and welfare of fish and the nutritional value of farmed seafood. However, the long term effects of such interventions and over the full life cycle of the major species farmed in Europe need to be determined. To answer this challenge, ARRAINA will define and provide complete data on the quantitative nutrient requirements of the five major fish species and develop sustainable alternative aquaculture feeds tailored to the requirements of these species with reduced levels of fish meal and fish oil. By developing innovative vectors to deliver specific nutrients, ARRAINA will increase significantly the performance at all physiological stages thus improving overall efficiency of fish production. ARRAINA will apply targeted predictive tools to assess the long-term physiological and environmental consequences of these changes in the different species. This will provide flexibility in the use of various ingredients in the formulation of feeds which are cost-efficient, environmentally friendly and which ensure production of seafood of high nutritional value and quality. ARRAINA will design and deliver new pioneering training courses in fish nutrition to increase research capacities and expertise, particularly in countries of the enlarged EU. By developing applied tools and solutions of technological interest in collaborations with SMEs, ARRAINA will further strengthen the links between the scientific community and the EU feed industry and will contribute to increase the productivity and performance of the aquaculture sector leading to competitive advantage to the whole sector at a global level.

With the rapid growth of aquaculture seen in recent years, one major fundamental problem has arisen being the environmental pollution due to increased numbers of escapee fish interacting with wild populations. A greater public awareness, the need to protect natural resources and increase the food safety requires the development and implementation of new environmental regulations. There is therefore an urgent need to address this negative environmental impact of salmon farming. To date, two means are available 1) preventing fish escaping by improving cage design and containment or 2) produce sterile fish. Although considerable technological advances have been made in the design of cage systems, no system will be fully reliable as escapees through natural disasters are inevitable. Therefore, there is a clear need to revive the previously abandoned triploid concept as the only means, known to date, to address the environmental impact of escapees contributing to genetic pollution. Furthermore, the production of sterile fish would be very beneficial to salmon breeders as a way to protect their domesticated stocks which are the result of long and costly selection processes aiming to improve important traits such as disease resistance, growth performance and flesh quality. Triploidy would also alleviate early maturation problems and subsequent welfare associated infringements and decreased quality standards. However, prior to discussing the potential implementation of such a radical change within the salmon farming industry, previously based on equivocal results, a sounder understanding of triploid requirements and performances is needed at a commercial scale given the significant advancement in rearing protocols made throughout the production cycle over the last decades. It is only through the establishment of a strong trans-national collaboration supported by key players of the salmon industry that such a project can be undertaken.
