Research & Reports: 2007

2007 – Salmon lice or suboptimal water quality – Reasons for reduced postsmolt survival?
 Rivers in Norway have been impacted by acidity; however, little is known about the interactive effects of water quality and louse infection on juvenile salmon survival. In this study, Atlantic salmon smolts were exposed to various levels of acidic freshwater then infected with larval sea lice in sea water. This is the first study showing that the combined effect of suboptimal water quality and salmon lice can significantly increase mortality in Atlantic salmon post-smolts.

2007, December – Salmon Farms Drive Wild Salmon Towards Extinction.
A study appearing in the December 14 issue of the journal Science shows, for the first time, that parasitic sea lice infestations caused by salmon farms are driving nearby populations of wild salmon toward extinction. Read the research summary.

2007, November 29 – Encouraging Innovative Solutions for Sustainable Salmon Aquaculture. Speaking for the Salmon Series, Simon Fraser University.
The purpose of this dialogue-based workshop is to examine and suggest innovative ways for the BC salmon aquaculture industry to move forward in a sustainable fashion, with minimal impacts on the existing wild stocks and coastal ecosystems.
