December 20, 2017 — ELLSWORTH, Maine — For such a small fish, herring play a critical role in the ecosystem of the Gulf of Maine. Only a few inches long, the plankton-eating fish are an important prey species, providing food for top marine predators, and are an important source of bait for Maine’s $547 million lobster industry.
In the Gulf of Maine, besides feeding whales, seals, harbor porpoises and dolphins, herring, particularly juvenile herring, provide a principal source of food for sea birds such as Atlantic puffins, razorbills, common terns and Arctic terns. Much of their catch is fed to young birds still in the nest.
In the water itself, top predators such as bluefin tuna, bluefish and striped bass, as well as cod, hake, pollock, dogfish and many species of shark, feed on herring.
Man is another top predator that relies on herring. In 2016, fishermen landed more than 77 million pounds of herring in Maine, most of it to be used as lobster bait, and most of it caught by trawlers fishing far offshore. That number is down from 103.5 million pounds just three years ago.
Not surprisingly, the price of lobster bait has climbed significantly. According to the Department of Marine Resources, the price of herring increased 57 percent between 2014 and 2016, and lobstermen saw the price of herring increase by a third or more, according to Maine Lobstermen’s Association President David Cousens.
