A Shelburne Harbour fish farm has been ordered to kill all of its salmon because a virus previously found there has spread. Fisheries Minister Sterling Belliveau says the Canadian Food Inspection Agency gave the order to Cooke Aquaculture's fish farm in Shelburne. In February, the federal agency ordered the company to kill fish in two pens and quarantine its site after an outbreak of infectious salmon anemia was detected during routine testing. Belliveau says the latest order will result in the deaths of thousands of fish in up to 24 pens. However, Belliveau doesn't believe the virus has spread beyond the site, adding that it hasn't shaken his confidence in the farmed salmon industry.
