If you are cat fishing you can stay in one spot and catch all you want sometimes.

But if you are bass fishing and if you haven't had any strikes in the last 15 minutes or so , there are two possibilities- they are not biting or they are not there.
It's time to move and try to locate some. The only time that it is in your best interest to stay in one spot when bass fishing, is when you locate a school of bass.

You normally have to hunt the bass down- one or two at a time-bass like the edges of things - the edge of a shoreline, the sides of standing timber in the water, the edge of a log laying in the water, the edge of a stump in the water , the edge of a weed line in the water, the edge of an under water drop-off etc.

The more targets you have in the water, the better your odds at catching a bass. Here's my philosophy on moving or stationary for bass- if I haven't caught a bass in 5 minutes, the bass are not biting there or there is no bass there.
