Day 3 Cohen Inquiry Disease Hearings
By Alexandre Morton
Dr. Kristi Miller took the stand today to finally explain what she knows about the health of the Fraser sockeye. The court room was filled to over-flowing. It is first time she has been able to speak to the public about what she knows about our fish.
Since 1995, so many Fraser sockeye are reaching the river but failing to spawn that today DFO has to figure out how many are going to die, before they can open a fishery. So in 2005 they tasked their scientist Dr. Miller to use genomic profiling to read the sockeye salmon cells to try and figure out why they are dying. Genomic profiling reads 10,000s of switches that turn on/off in cells in response to starvation, toxic blooms, high water temperature, good feeding etc. When Miller read the cells of the Fraser sockeye she found all the ones that were dying had very similar genomic signatures. This suggested they were dying of the same thing. The cellular switches that were turned on and off were ones that respond to viruses. No one expected this.
All this is going to be very interesting to follow..............
