Researchers Find Sea-lice Transmit Disease

Preliminary results from researchers at DFO's Pacific Biological Station have confirmed what many have long suspected: sealice can act as disease vectors carrying pathogens between salmon farms and wild populations. While the impact of the parasites has long been established the new study adds another layer of concern. In recent years populations of wild salmon in the Georgia Basin have collapsed prompting a wave of research and a judicial commission to investigate the factors associated with the decline of Fraser Sockeye and other nearby stocks. While scientists long ago established a link between juvenile mortality and sea lice parasitism, mounting evidence suggests disease is likely a major factor in the decline of salmon from Vancouver Island to the Puget Sound.
