We propose a joint inter-sectorial training network to increase the mobility and visibility of scientists between aquaculture research and the biomedical sector using small fish models. The proposed ESR programs will provide career development to young researchers in the field of skeletal biology through international and multidisciplinary training on innovative molecular, histological, biochemical and cell culture methodologies relevant to both sectors. The network combines stakeholders from 7 European Universities, a US research hospital, and one Biological Institute. Commercial interests are represented by two Economy departments, one aquaculture and a major fish feed production company. This structure allows the flow of information and people between the biomedical and aquaculture sectors, and between academic and applied sectors, thus addressing several objectives of the Europe 2020 strategy and ensuring a direct route from knowledge to application.
