I filmed this today on the Fraser River. I have had many different options what they are when I posted the video on FB, your thoughts.

yes

Definite yes. Matter of fact just bought some from Super Store. Going to fry them up for supper. Delicious.
-
I went down and caught one, they are sticklebacks, pictures on my FB page.
-
So they are. I didn't know they migrated like that, learn something new every day!

Going by in the thousands too.

"These are the anadromous (sea-running) form of the Threespine Stickleback (Gasterosteus aculeatus). The anadromous form is known as "trachurus". Like a sea-going salmon they are dark on the back, white on the bottom, and silvery on the sides. The non-anadromous form of this group is known as "leiurus" and is found in the ditches and sloughs around Chilliwack (as well as elsewhere). https://www.nrcresearchpress.com/doi/abs/10.1139/f67-138... Threespine Stickleback are found circumglobal north of 30 degN. You can find them in Great Britain, and other parts of Europe, for example. https://en.wikipedia.org/wiki/Three-spined_stickleback

Thanks Chris! Cool video. I never realized there was an anadromous version of stickleback that called the Fraser home.
-
x2 Nor I! Very cool to learn that. Pretty amazing that a little fish like that has a spawning migration so far upstream.
Anyone know where their spawning grounds are?
All the more reason to protect the Heart of the Fraser. Those stickleback are an important part of the food chain of inshore marine areas.
This pot bellied jack coho was caught in Sept off a saltwater beach

was plugged with these stickleback.

I counted 25 intact stickleback and a mass of digested ones.

Really cool to see that

Stickleback-the new Oolichan :o
I never knew about this run of fish either.
Very cool to see.
I seen something similar in a local river but it was a mass of Red sided shiners in a full on spawning mass.
They were about the same size as Oolichans as well.
-
I went down this morning 3 days later after the video and pictures I shot and I observed them still going by by the thousands. One could maybe say the millions now.
-
Chris, you just might be the first to document this migration 8) , very well done!
Marvin could probably suggest a few people at UBC who would be very interested in this.

Yes Marvin asked me to send to UBC which I have done. Rodney and I going tomorrow and see if he can get some underwater shots if they are still going by. One can only imagine how many have gone by in such a wide stretch of the Fraser. Now over 6.1 K views when I last looked on the video I put up my FB page and more on the link when I posted to youtube too.
-
Photo journalism at it's best :) Again, great job.
-
Today Rodney and I went down to do some filming of the anadromous (sea-running) form of the Threespine Sticklbacks that I filmed last Saturday. We were wondering if they would still be there but they were.
Rodney shot a lot of pictures and video footage including some underwater shots. He will be putting a video together of them.
Also we did another video about illegal dumping beside a pile of drywall someone dumped a few weeks ago at the Bert Brink Game Reserve.
Rodney may have them up as early as today so watch for them.

:) Interested to learn more about them

So this is whats been happening with all the Salmon disapearing. ::)
-
Quite an enjoyable morning without wetting a line!

These fish are tiny, but the scale of this migration is absolutely amazing.
-
I remember seeing those little guys going up the shallows, back when the Fraser was open for Chinook in May. I remember asking a few of the others on the bar fishing what they were, and no one knew. Good to know what they are after all these years!

How long ago was that blueback? The more info about these guys, the better.
-
the population must of really increased in the last few years.
Shared this video with Bugs, a uvic researcher who has been sampling chinook stomach contents for the last few years. This migration corresponds with the timing he has documented three spined sticklebacks in chinooks stomach caught in the ocean off the fraser river.

also the new herring!
-
Sounds like it's just a rare massive return which no one has seen before. I've been getting lots of messages from people who have had similar observations further upstream and in the tributaries like the Sumas.
-
"How long ago was that blueback? The more info about these guys, the better."
I guess it must've been in the later 90's. I remember seeing them during several years.
-
shared the video with a few bio's, There response : "That is extremely cool. Thank you for sharing it. I knew that these guys were anadromous, but had no idea that migration occurred on that kind of scale"
thanks again Rod for bring awareness to this
-
At 4:30, look at the size of, and how predominant, their eyes are.
Now I realize why some baitfish fly patterns use stick-on eyes.
-
The scale of the migration is most likely a rare occurrence. The key questions then would be, is this a regular peak cycle that occurs once every few years? Or is it happening due to changes in the ecological balance in the ocean (less predation, more primary productivity, etc)? Still many unknowns out there.

'like'
FWIW-I cross the North Arm twice every AM for work and just noticed how the freshet has grown/was wondering what changes were happening but had no idea about this amazing event.
Thanks for your efforts.
