Could this run of sockeye be last years fish being 5 years old?
-
Doubt it, I believe scales are like tree rings, you can use them to tell age...if a whole whack of fish for some odd reason cam back a year lete (ie 5 year olds) DFo could tell. I am fairly certain DFO does genetic testing and collects scale samples from the test fishers so I think they would have picked up on that if it were the case.

Interesting idea, would be good to hear from DFO on that one.

the pitt gets 5 and 6 year sockeye...but no I doubt the sockeye would have skipped last year and became 5 year fish.

What are the chances that they dont always return to their original river system?

If so then they would be bigger average size

DNA sampling has shown that the bulk of these 30 million fish are Shuswap stock.
The majority of the missing fish last year were early and mid summer runs. Last years Adams run was never supposed to be more than a million fish at best.
-
Yup...they were Chilko and Quesnel fish that didn't show last year, not Adams/Late Shuswap.
But if there weren't as many 2009 sockeye feeding out in the ocean, maybe there was more food around for the 2010 fish so they survived better....
-
Not sure of the source but I heard that some systems had as high as 22% of the run being 5year old fish. More than normal, but not enough to create the abundance of fish reported to date.

From what I've been told, the Pitt River sockeye generally are a larger fish.

They found Fraser River fish in Port Alberni this year, that's what I was told anyway.
