I have been patiently scouting a local river that is new to me and have visited several hot spots that do have evidence of fishing pressure. Unfortunately, it wasn't the day that I was going to update my profile with a pic of a lunker. However, over the 3 hours that I was there, seven or eight steelies were landed, all of them were boyz!

Stats... Sunny morning just below freezing, temps / barometer were on the rise as well as streamflow as thaws were slightly in motion.

Is this a fluke that only bucks were on the bite or do the prevailing conditions have any affect on this behavior ?

I've never seen that many bucks landed in a row. So I would say it was a fluke. Probably just more bucks than hens in the hole.

If there was quite a bit of pressure on the river it could be that no one was releasing hens if caught. Here in Oregon with many streams having a two fish limit, some will release bucks in hopes of catching a hen to retain so they have eggs to cure. Not exactly what the department of fish and wildlife wants but it happens.

No 'Ladies Night' signs posted at the hole, all bucks on the bite and nothing but dudes fishing. I could've merely chalked it up to a massive deluge of testosterone.

I thought there may have been some scientific reason, but you both summed it up deductively.

Thanks for the input men!
