I have found that silvers are very unpredictable as to when they go on the bite. I have tried looking at my logs and charting tides, day light, depth, etc... and can't find a real pattern.
The only thing is you want to have lines in the water when the bite turns on because when it turns on it is usually fast and furious action. Put in your time and you will get fish! moose
