The wild stock used to have a female to male ratio of 1.5 to 1.

Keep in mind there is some bias in retention fisheries - e.g. anglers might be more inclined to retain females for their roe, or larger bucks for trophies.

Love these old reports, younger people get to see what this river once was, and it appears the sex ratios have changed radically since hatchery production began.

[CohoJake]

Looking at the past few years of Fred's derby records, it does seem like this year is on the extreme end for number of females, and other years look close to 1.5:1

Yes the previous year there was more males, Comparing these values to the old report I dont no if they are statistically that different that you could come to the conclusion that they have changed as a result of the hatchery.

"For 1958-1975...timing of the run found the best month to be December, and Dec 23-21 the best week..."

What a change!

[wildmanyeah]

I found this comment interesting "during the month of january the higher portion of males may indicate the start of the late run"

Its hard to tell from the paper but it almost seems like the late run is stronger then it once was. Altho talking to old timers one said that the March run of fish was always there but not predominantly fished.

in 1950 the caught sex ration was as high as 2.5 to 1.  However the sample size of that year was only 35 fish. With freds numbers were dealing with a sample size for last year at 155. If you look at 1952 that has a large sample size of almost 400 fish its around 1.6 to 1. That is pretty close to what 70/30 number that AA said.

[Steelhawk]

Looking at the derby results on Feb 7 especially Feb 8 (6 fish) and comparing the report of poor water clarity of about 1 ft on those days for the lower river, it makes one wonder if water clarity at 1 ft or so is good enough for good catches as on those 2 days. The river was very high too in those 2 days at about 2.5 in river level chart, not a favourable level to dig out fish in flooded runs. Perhaps the presence of more fish on those days is more important than perfect water condition. PS. I fished yesterday afternoon strictly pocket water in mid river from Tamihi and down at 1 ft visibility and didn't have any hook up. Disappointing considering the high water should bring in fish and 1 ft visibility should be good enough for fish in pocket water to see.

The fish have always been there and I highly doubt it is stronger now than back then. 
There were other places to fish come March and April. Even now after a long winter angling pressure drops off in March and not very many in April, mind you it is growing.
All the guys I fish and did fish with quit fishing the Vedder/Chilliwack by March and spent time going elsewhere.
Vancouver Island rivers really turned on in February and March and then there was the Squamish system, Nahatlach, Bella Coola & Chilcotin that are all virtually no longer viable or just plain closed.

Spot on redside1..  back in the late 60's and early 70's is when I fished the most, and the lack of angling pressure in March and April made some stellar fishing days. The winter run was strong but the late run was phenomenal  I could mention numbers but that would only piss off some people, lol!

[chris gadsden]

River was better looking today but too colored for me but maybe just looking for an excuse to be lazy.

[Wiseguy]

Any updates on the number of brood stock fish captured so far?

[chris gadsden]

Any updates on the number of brood stock fish captured so far?

I saw a post they had reached their 60, someone else can confirm.

[Wiseguy]

Oh wow. That’s pretty good. So they done for the season then?

[avid angler]

30 does and 22 bucks. 8 more males to go.

[Rodney]

Sorry, never got around to create a new thread for this so splitting it up from the fall salmon thread now.

River conditions have been good. Fishing has also been good, for other people. Both COs and DFO officers have been regularly checking anglers, good to see.
