I'm not sure where those data are coming from, to be honest. We've done a five-year tracking study of Chilko Lake salmon and their out-migration. The first thing is that we're only measuring the survivors that have been lake reared for one to two years. They normally rear for one year or two years in this very high elevation lake, Chilko.
Over the five years, between 30% and 50% of the fish didn't make it even to the ocean, but most of those died before they got to the Fraser River coming down the Chilcotin system, so that was particularly bad. We saw very little mortality in the lower Fraser from the confluence of the Chilcotin to there.
There have actually been very few studies with a rise, measuring the survival of salmon in the Strait of Georgia. One study recently published—and I can send this to you if you're interested—actually looked at the amount of time that was was spent by sockeye salmon migrating past salmon farms. The first thing was that two-thirds of sockeye went straight up the Johnstone Strait and avoided the Discovery Islands and the farms located there. The ones that actually had receivers that ping.... It's the same sort of little transmitters that ping if you're trying to steal stuff going out of a store. It's the same sort of technology, so you know how long they are around pinging on a salmon farm. They have a range of 200 to 800 metres. It's a matter of minutes. One-third of the fish are passing by salmon farms and they are spending a matter of minutes in association with a salmon farm. That's the period of contact. So whatever contact and impact you're imagining as a risk have to happen within that contact time. That study came out in 2021. That's how limited the knowledge we have is.
I'm not sure about the data you've heard. I haven't listened to all of your committees. You're a very patient committee, trust me. There is a lot of information out there, and I'm not on top of all of it, but I hope that helps a little bit.
