Gene editing could boost sea lice resistance in Atlantic salmon: study

Researchers from the University of Stirling’s Institute of Aquaculture have contributed to a groundbreaking study that could enhance the resistance of Atlantic salmon to sea lice, a major challenge in aquaculture. The study, published in BMC Biology, reveals that keratinocytes in the skin of coho salmon, which naturally resist sea lice, play a crucial role in initiating a defence response. By understanding these cellular mechanisms, scientists suggest that gene editing techniques could be used to improve sea lice resistance in Atlantic salmon, potentially reducing the reliance on costly and environmentally harmful treatments. This research offers a promising avenue for sustainable aquaculture practices. (The Fish Site)
