I don't know about some of these posts. "Back in the days, back in the days," I really get tired of hearing about how good we had it in the old days. It all trivializes what fishers did way back when. Maybe there is something above that I don't understand; I prefer to think that.
Rag, I don't know the difference because I have no experience with sea herring. I only know that they get larger than alewives, are high in protein and are not the same fish. Herring used as a colloquial name for alewives is just not accurate.
