Sea Lice From Farms Found on Fraser Sockeye

In a publication out this week. Canadian researchers have for the first time shown that sealice from salmon farms transfer to Fraser River Sockeye and that Sockeye which migrate past salmon farms have an order of magnitude higher rate of infection than fish from non-farming regions. While the role of sea lice in the decline is still not fully understood, salmon farming operations are thought to be among the most likely causes of recent the declines in marine survival for Fraser Sockeye.
