Alright Bass guru's.... solve this one:

Three weeks ago, the big bass bite was on. I scored a couple over 5#s, which ain't bad, but fishing buddies of mine were using jig'n pigs on a different pond and caught fish over 8#s and one in the 10# class. In the last two weeks, the big fish seemed to have just shut off.

Fish still aren't on the beds. We are catching tons of males, I think I caught in the neighborhood of 30 in about 4 hours this afternoon, biggest fish was around 2.5#s, typical pre-spawn male, healthy and aggressive. Caught all my fish either on spinnerbaits or crankbaits.

Now, a few weeks ago the weather was pretty warm and the water temp started coming up. Today it was a bit cooler, the nights are getting down into the 40s again (I'm in central/eastern VA and fishing farm ponds). Water temp is still just a touch under 60, and we had a bit of a weather system moving through today, cloudy and windy and cooler. The big fish bite seems to have shut down, but the smaller fish are still feeding. Today the weather had them a bit sluggish and some of the hits were sluggish... the trailer hook saves the day again.

I'm thinking perhaps the colder weather has their metabolism slowed down a bit? Maybe they are movnig to and from shallow to deep water to feed and I just missed the cycle/window of opportunity? I couldn't buy a bite on a worm today..... not even a pick up on the black worm or the senko. Usually they are good for at least a fish or two, and usually are the most consistant producers of big fish for me.

What do you think is going on?
