I've been casting to gills on the beds the last two times out ( over the past week) with many different patterns:

Wb, damsel nymphs, PT , GRHE, scuds, generic nymphs & soft hackles ( all dark colors) , wooly worm ....

I get very little action.. maybe one hit and then nothing. I'm at least 30 to 40 ft away with a 8 ft leader. I'm not looking for a new killer pattern but trying to learn something about this behavior. I expected very aggressive male attacks in the bed area. I know they are in the beds because I have crept up on the bed area from the shore and can see them.

Is it possible that the eggs have not been layed yet so the males are not protective..... The most aggresive takes have been in non-bedding areas and the fishing there has been as expected.
