In March, the Government of Canada announced research support for a $4.7 Million Complex Gill Health Initiative that will focus on Complex Gill Disease (CGD), a growing health challenge for salmon farming operations in both the Pacific and North Atlantic. This project, co-led by Genome Atlantic and Genome BC, will validate biomarkers of healthy and compromised gills of Atlantic salmon and use these to develop an early warning system for the development of gill disease on Atlantic salmon production sites across Canada. The resulting genomics-enabled tools for fish health will guide the management and intervention strategies for complex gill disease in Atlantic salmon.
