Craig Orr’s letter to the editor of the Vancouver Sun The relevance of sea lice, toxins and fish still debated
Watershed Watch Executive Director, Craig Orr, responds to Mary Ellen-Walling’s letter Industry disputes fish farm sea lice is harming wild salmon, Vancouver Sun
Letters, Feb. 17, in the letter to the editor The relevance of sea lice, toxins and fish still debated. One key point that Orr points out is that scales are not enough to protect salmon from sea lice. “Smolts with scales, and larger than juvenile sockeye, have been absolutely decimated by farm-source lice in Europe. Dozens of papers document this sad fact. Another paper on B.C. coho published before Christmas suggests lice have serious impacts on larger predatory fish (with scales no less).”
For more information on this topic, see Watershed Watch’s Salmon Farming page as well as the recent PLoS One paper Sea Louse Infection of Juvenile Sockeye Salmon in Relation to Marine Salmon Farms on Canada’s West Coast mentioned in both letters.
