Researchers at Nofima are exploring the possibility of including cleaner fish, such as lumpfish, in the human food chain, as they are currently discarded after being used in salmon farming. This project aims to address the challenge of millions of cleaner fish dying in salmon cages annually and seek sustainable solutions. The research covers the entire value chain, from sorting and processing to market analysis, and includes experiments with gentle removal of cleaner fish from cages and improving anesthesia for slaughter. While it may be challenging to introduce small lumpfish on the Scandinavian market due to consumer preferences, potential markets in Asia are being considered for their approach to utilizing various seafood. The success of this venture depends on developing efficient production and transport methods that maintain quality and making the process profitable.
