Sometimes it's getting back to basics. Eels or drifting sandworms in a tidal river will pretty much guarantee a fish, betcha I just put the curse on that.
It also sound like you have been trying too many spots, sometimes a few good spots are better than chasing fish someone caught yesterday.

I fished 21 nights this month. it was slow, i got fish, but it was slow. Every one gets skunks. Keep at it, eels and bucktails and put in your time to places you know. Youll get fish, May aint over
