Welcome to Maine:
Alewives Need Not Apply


If you were a native animal which has lived in the fresh and salt waters of Maine for 9,000 years; fed countless generations of people, fish, bear, mink, otter, osprey and bald eagles; been driven to extinction by dams and pollution but still maintains a slender hold on survival in a few Maine rivers today ...

If you were that animal, you would be surprised to find many Maine people don't want you back.

If you were that animal, your name would be the alewife (Alosa pseudoharengus).

The alewife is an animal once as familiar to the people of New England as the chickadee, the cod, the monarch butterfly or the white-tailed deer. The arrival of tens of millions of alewives to the rivers of New England was long known by all as a sure-fire sign of spring. Alewives were caught by the millions from our rivers and streams, some to be smoked or pickled, others to fertilize fields of corn, others to be used as bait for cod, striped bass and halibut.

To survive, alewives must migrate from the ocean to their spawning grounds in freshwater ponds. Alewives have been doing this in New England for 9,000 years.

In 1735 the Great and General Court of the Massachusetts Bay Colony passed the first law in North America to protect a native fish in freshwater. The fish they chose to protect was not the Atlantic salmon, the brook trout or the sturgeon, but the alewife. The law reads in part:

"An Act to Prevent the Destruction of the Fish called Alewives.

"Notwithstanding the provision of law already made for removing incumbrances obstructing the natural or usual course of fish, in their season, in brooks and rivers, yet no sufficient remedy is provided where such obstruction is occasioned by dams erected for mills, &c. which is to the grievous damage of his Majesty's good subjects in diverse parts of this province, more especially where such dams have been made across rivers through which alewives or other fish have been wont to pass, in great plenty, into ponds, there to cast their spawns; wherefore, to prevent the like inconvenience and damage for the future --"

Despite this 1735 law, which required all dam owners to let alewives pass through their dams or face heavy fines, and countless more laws with the same intent passed during the next two centuries, one by one the rivers and streams of New England were closed off to the spring migrations of the alewife.

By 1970, alewives were extinct from more than 95 percent of their homes in Maine and New England. By 1970, for the first time in 9,000 years, most people living in New England had never seen an alewife in their lives, nor had their parents or grandparents.

Thirty four years later, the situation has not improved significantly. Alewives remain shut out of most of their native homes in New England's rivers, as are Atlantic salmon, American shad, Atlantic sturgeon and striped bass.

With the passage of the federal Clean Water Act and removal of gross pollution from our rivers and lakes, efforts to restore alewives to Maine have escalated. So quickly that many Maine people have been caught off guard, having lived so long without even the memory of sea-run fish swimming in the rivers and ponds near their homes.

The absence of sea-run fish from Maine rivers and ponds has been so long that some Maine people are now opposed to letting these native fish come back and have stopped the restoration of sea-run fish, including alewives, to their native habitat in many Maine rivers, streams, lakes and ponds.

Maine is the only place in the United States or Canada where citizens and state fisheries biologists have opposed the restoration of alewives to their native homes in the state's coastal watersheds. Despite their refusal to provide any scientific evidence to support their claims -- and the refutation of their claims by innumerable scientific studies -- many Maine citizens and state fisheries biologists continue to oppose allowing alewives to return to their native homes in Maine's rivers, lakes and ponds.

Because of this opposition, decades-long efforts to restore the native sea-run fisheries of two of New England's largest river systems -- the St. Croix and Androscoggin -- have severely faltered; and this opposition is now threatening 100 years of efforts to restore the sea-run fisheries of the Kennebec and Penobscot Rivers.

Below is a wide range of information about our friend the alewife.
