Improved Production Strategies for Endangered Freshwater Species

Overfishing and anthropogenic activities have critically endangered the wild populations of iconic migratory fish species. A major problem of past stocking measures has been the high mortality of juvenile fish after their release. IMPRESS builds on the latest scientific advances to develop innovative production techniques and ensure the survival of migratory fish. Such a paradigm shift requires changes at all levels of the production cycle. New in vitro and -omics technologies are being developed to address current bottlenecks in the production cycle. In IMPRESS, researchers also consider the social dimension of this complex issue. All IMPRESS fellows are actively working to increase public awareness of the environmental importance of migratory fish species and the great social benefits of healthy fish populations.
