“Our results suggest that sea-louse counts reported by the salmon farming industry are lower than the true abundance of parasites on their fish. When the federal government audited a sea-louse count, the industry’s mean counts for that month increased by a factor of 1.18 for L. salmonis and by 1.95 for C. clemensi.” – Sean Godwin et al, Bias in self-reported parasite data from the salmon farming industry.
Dr Sean Godwin is the lead author of eight of the fifteen scientific papers listed on his website. The bulk of these explore interactions between wild and farmed salmon. One of the most troubling, published in the journal Ecological Application, is a survey that showed fish farms underreport sea lice when they are not audited by Fisheries and Oceans Canada.Continue reading Fish farms underreport sea lice when not being audited, study says
A marine archaeologist at SFU is launching an ambitious study to find evidence of how people first migrated to North America over 15,000 years ago.Continue reading How people migrated to North America
Scientists are just becoming cognizant of the environmental consequences. According to the Hakai Institute, which operates an ecological observatory on Quadra Island,10 million cubic metres of rock and earth plunged into Elliot Creek on November 28th. Andrew Schaeffer, a Pacific division seismologist with the Geological Survey of Canada, said the landslide “sent out low-frequency surface waves resembling those of a quake with an equivalent magnitude of 4.9.” The glacial lake outburst was about 100 metres high and to shot through Elliot Creek into the Southgate River and Bute Inlet.Continue reading environmental Consequences Continue: Bute Inlet landslide
