When it gets dark so early in the Fall, does this change how the Bass feed at night? During the Summer when it gets dark around 10pm I usually have real good luck fishing from dusk through the first couple hours of dark. Now when it's getting dark around 7pm I can't seem to catch any Bass at night.  >

This biggest thing I noticed was that you can't even hear any Bass feeding at night now. During the Summer nights you would hear a few of them jumping and splashing near the shoreline and now it's just dead calm without a Bass so much as making a ripple on the water.  

The first night I went out from 6:30pm to 8pm

The second night I tried from 8pm till 10pm

the last night I went out from 8pm till Midnight and only had one strike for the three nights and never heard one Bass surface?

I did catch a lot more than normal during the early morning hours so I was wondering if they quit feeding at night and start feeding during the day?

The only other thing that I think could have affected them this past weekend was that there wasn't any Moonlight and it was dark as heck.   :-X

During the Summer the Moonlight is so bright sometimes that you don't even need a flashlight.  8-)

Our night bite dies also as the cold air arrives.   I don't know if there is a special temp that triggers this but once they start their cold water preparation, we don't even start fishing till the sun has had a chance to heat up the rocks that their food is still relating to.  

I caught a 20" smallie just after dark on a Pop-R last weekend. Wow was that a fun fish. Hope to get out tomorrow, not many good days left up here in Michigan. Oh ya, I also caught a 19"and 20" largemouth that same evening, both on a Sweet Beaver on a 1/8 oz jig head. Great day of fishing for me!!!

I have fished at night for smallies and it seems that they shut off after it starts to cool off.  I have been luck about the first two hours of dark.

I no longer have the cojones for cold nights.
