Throughout August into September in fact right up to yesterday most of my grilse and salmon have been cock fish. Is this pure chance or have any other forum members encountered this, any gillies out there who have handled more fish than anglers have might provide the most accurate picture.

I've had 17 cocks and 5 hens this year, a few others that I have spoken to have had similar results

Most of my fish off the conwy in September have been cocks, only a few hens.

I think the last 10 of so of our fish from the Avon last week were all cock fish. Are the ladies lying low, or will there be a bit more of argy-bargy on the redds this year?

Hello bogyoch, what I am wondering is: are the cock fish more aggressive and likely to take a fly or lure? Or are there in fact the ratio of cock fish to hens in the river as is reflected in anglers catches? ? Tweedsider

There is generally a higher proportion of hens to cocks in the earlier part of the year and this is normally reversed at the back end, obviously being a higher proportion of cocks. However, it isn't always the case and sometimes I have been astonished to catch almost entirely hens or cocks in particular years or seasons of the year.
A higher proportion of the cock's will die and very few will survive to spawn a second time, the hens have a lower mortaility rate and a higher proportion will spawn again. Fortunately, any mismatching of numbers between cocks and hens are balanced out for the salmon because there are extra fertilising males in the form of sexually mature parr.

Just spoke to a friend who works in the Tweed netting industry and sends regular scale samples for scientific evaluation or words to that effect. He, like fruity, spoke of different sexes and different sizes entering the river apart, also that up until the end of the netting season he was recording very few hen fish for this purpose. If there are any gillies on this forum perhaps they could keep us up to date on what the ratio is .

We had fish-counters on two burns on Deeside that consistantly returned an average ratio of about 5 cocks: 1 hen in the autumn months. This was counting several thousand fish over several years. Not sure exactly why, but backs up other comments on here.
