Sardine Industry

For millennia, Wabanaki peoples have harvested Atlantic herring, once an abundant food source along the coast of Maine. When canning technology made preserving mass quantities of food cheap and effective, Maine, with its robust working waterfront infrastructure, was uniquely suited to become the center of the canned sardine industry.

From the nineteenth century through the mid-1900s, cans of Maine sardines – young Atlantic herring caught off the coast – were a staple of the American diet, found on dinner tables, in lunchboxes, in school cafeterias, at logging and sporting camps, and as military rations.

Many coastal communities had at least one cannery, and some, like Eastport, had dozens. But as tastes changed, the inexpensive cans of sardines that fed working families for generations became less popular. With demand dropping and management of the fishery tightening, the sardine canning factories began closing. The last sardine cannery in the United States – in Prospect Harbor – closed in 2010.

Throughout its history in Maine, the industry employed thousands, especially women, whose work at the canneries often complemented the labor of their male relatives in the fishing industry. While the shift-change whistles and the chatter of the factory machinery are silent now, the voices of some of those cannery workers have been preserved in oral histories.
