I did also specify coastal societies. Evidence suggests that while there was some light agriculture that was no where near the bulk of their calories. Those primarily came from marine sources.
Everything I know about Native American coastal societies in the southeast, which admittedly is nowhere near my specialization or main field of interest, refers to them in context as agricultural and maize-oriented. Only a few societies along the the Caribbean were both sedentary and predominantly dependent on the sea for their sustenance, and the largest I know of, the Calusa, practiced aquaculture, which is more comparable to pastoralists than hunter-gatherers.
