CRISPR/Cas9-Mediated Gene Editing in Salmonids Cells and Efficient Establishment of Edited Clonal Cell Lines
Finfish production has seen over three-fold increase in the past 30 years (1990–2020), and Atlantic salmon (A. salmon; salmo salar ) accounted for approximately 32.6% of the total marine and coastal aquaculture of all finfish species in the year 2020, making it one of the most profitable farmed fish...
