Trends in antimicrobial use in Marine Harvest Canada farmed salmon production in British Columbia (2003-2011).

Abstract

Marine Havest Canada has significantly reduced its antimicrobial usage in salmon farming over the last 8 years. Change has come about largely through improvements in production, health management, and livestock selection. However, antimicrobial treatments are still required for stomatitis and bacterial kidney disease. Lack of efficacious vaccines and the limited number of licensed antimicrobials available to the industry continue to be of concern.
