Thanks for the video. It is somehow reassuring to know that those fish are out there moving nutrients through the ecosystem in Quebec. I can only hope that Atlantic salmon stocks in the East continue to expand in the US and Canada. I have eaten fresh A. salmon in Ireland and it was really good.
I worked in Alaska often doing water quality monitoring around salmon streams. It is really impressive to be around salmon all day. There are 4 runs of Pacific salmon and after awhile they are easy to tell apart. In that country, salmon runs mean bears, all the time. They are amazing to watch. I have seen hundreds of salmon herded with the prop wash on a helicopter. Fish with large claw marks. All of the biggest fish I have ever caught have been spawning salmon by hand in shallow water wearing waders.
