In my experience around here, Herrin's, herrin's......and more herrin's
Luuuuuv dem Herrin's. I dead float em whole, chunk em, live line em. Luv em. For the rivers, 'specially in the marsh, herring spells C A T C H. Mackerel will get this many hits in 6 hours of fishing in the marsh --------> 0. Macks seems to work better for me offshore from the boat. Clams work well off the jetties and in the surf. Live eels work GREAT for me in the bays and at the mouths of the rivers/creeks. Pretty much have a different presentation for different spots.
