Lower Sea Lice Levels in Broughton Archipeligo in 2009

Good news for salmon populations in the Broughton Archipeligo. Like many populations of salmon in the Georgia Strait, Fraser region outmigrant salmon are forced to pass countless salmon farms during their outmigration. One of the biggest problems with the salmon farming industry is the high consentration of parasitic copepods known to the public as sea lice. Normally not found in high concentrations on smolts, they are capable of killing the young fish when their numbers are unnaturally high.

Research done this year by Marty Krkosek and DFO researcher Brent Hargreaves indicates sea lice concentrations for the season were down in the Broughton Archipeligo, an important salmon producing region which has been plauged by sealice outbreaks in the past. The lower levels of sea lice are being attributed to CAMP or the Coordinted Area Management Plan where a number of salmon farming operations were fallowed prior to the spring juvenile migration. By strategically fallowing certain farming operations scientists hope they can minimize the impacts of Atlantic Salmon farming on wild Pacific Salmon in the region. See the press release at the Georgia Strait Alliance.

Also see information and a video at their website about the effort to force the fallowing of five salmon farming operations to protect outmigrating Fraser River Sockeye.
