Chinook travel patterns

[Dragginbait]

Does anyone actually know or has there been any study on the travel of Chinook? Say there is a report of good numbers of fish in Renfrew, how long does it take for them to start showing up in Sooke. Is it dependent on current, feed or moon phase or just how fat and lazy they feel on any given day.
What I'm curious about is the fish that you are getting into today, are they going to be hanging around for a few days or are they going to be down the coast with the daily tide changes???
Have there ever been any monitored fish tracked during there migration?


Lots of question marks, but could be interesting.

How long is a piece of string?

Well I guess that clears that all up. Thanks LR

It's an interesting question.. I would assume there's a combination of the factores you mention, and put an emphasis on the availability of food. But for a general timing of locations they'd be in, check 2011 threads to see how hot it was at the same time last yr.

Another question I have along this same line is: where do the salmon go, if they're too young to spawn; say 3yr Springs, between the slow Nov-April months?

Ask or send a letter to DFO asking as they are the expersts on managing our fishery and say they know the patterns to the day????
be intersting to what they say......

All kidding aside sometimes I dont think the same fish im renny come this way i think a lot do but not all as its been bad there sometimes (prior week ) and hot in sooke I do think that the fish hang here more and feed in the past few years..

I've found that fish migrating into the straits will show up in Sooke about 2 days after they show in Renni.

If they show at all..

Actually, DFO and the Pacific Salmon Commission have a very good idea of where the fish go. Radio Frequency tags have been put into smolts released from hatcheries for a number of years. On the sea bed there is a string of "listening pods" which remotely collect data including specific RF tags when schools of fish pass by with tagged members. This is a really cool system run by UCLA and other member groups as part of a very large research study on oceanics. Same system is on the East Coast. There they catch and tag and release Atlantic cod, and have tracked the deep water migration route up through a cravass to the area off Eastport, Nfld, where the Cod then spread out for their summer feeding grounds up and down the coast.

RF tags can be individually serialized, so the Bios know the date of tagging and the size and run location that is being tracked, and continually tracked as the fish continue on their travels.

I do not know if DFO has a website with the data available for the public, though I suspect that it could be accessed.

Thats very cool, it's worth looking into.

I would be interested to know how much tagging and monitoring is going on these days in Canada. And if the information is reviewed and studied.

I did catch a hatchery white spring on Friday. I will be sending that head in hoping for some information. Can't think of many hatchery whites I've caught.

This is the POST site that has the tracking info on it.

I think it's all about the food . No food for fish to eat.....no fish.

They go where the food is.

On their migratory path down the west coast V.I., if they come to a place that has a rich population of bait fish , they will hole up there for awhile. if they do not find any at that spot they will move on.

I think they have built in sensors/biological clock that tells them overall how long they can stay in one place before they have to move on.

But they aren't going to hang around for too long in a place that has little food.

If they do hang around in a place like that they will eat species that are generally low on their menu or whatevers available.

But Mother Nature's clock is always ticking for them....

Looks like these guys are closing down http://www.vanaqua.org/media/media-releases/2012/pacific-ocean-shelf-tracking-program-closes.

I think they only tracked juvies as the batteries powering the transmitters didn't pack enough juice to last a fish's lifetime.

After chinooks pass Sooke waters, they may enter Puget sound rivers. We found a few hatch chinooks in our waters.
