The project aims to develop and implement new methods for sustainable industrial production of new healthy live feed for juvenile fish, thereby making fish production more sustainable and ensuring better survival of the juvenile fish. The project will use two dwarf worms (E. albidus and L. rivalis) that will be able to replace traditional live feed for marine fish. The project also aims to carry out innovative research to develop cheap and effective cryopreservation of live worms at an industrial level. The project is a collaboration between Aarhus University and the company Fishlab and is conducted by PhD student Mathias Holmstrup.
