Biology & Habitat

Appearance

Butterfish are dull blue on the top, with pale sides and a silvery belly. Numerous irregular dark spots fade after they are harvested. Very thin and deep-bodied, like a flounder set upright, and somewhat circular or rounded. Small mouths with weak teeth and blunt noses. 6 to 9 inches in length, though some individuals can reach 12 inches. Up to 1.25 pounds in weight.

Biology

Butterfish are short-lived and grow rapidly. Few live to more than 3 years of age, and most are sexually mature at age 1. Spawning occurs during June and July. They are semi-pelagic, and form loose schools that feed upon small invertebrates. They have a high natural mortality rate and are preyed upon by many species of fish, marine mammals, and seabirds.

Where They Live

Range Butterfish are found from Florida to Newfoundland, but they are primarily found from Cape Hatteras to the Gulf of Maine. Habitat Butterfish shift their distribution in response to changing bottom water temperatures. During summer, they move northward and inshore to feed and spawn. During winter, they move southward and offshore to avoid cold waters.

How to Buy & Source

Availability

Year-round.

Source

U.S. wild-caught from Maine to South Carolina.

Commercial Fishery & Harvest

In 2024, commercial landings of butterfish totaled approximately 4 million pounds and were valued at $3 million, according to the NOAA Fisheries commercial fishing landings database. Butterfish are primarily landed in Point Judith and North Kingstown, Rhode Island; Montauk, New York; and New Bedford, Massachusetts. They are generally exported to Japan, where they are a popular menu item. Otter trawls are used to catch butterfish. Otter trawls can incidentally catch other fish and marine mammals as bycatch, and can impact habitat, depending on where they are used. Gear restrictions (minimum mesh size) when fishing with otter trawls are used to reduce bycatch.

Sustainability Story

Not Overfished Stocks Stable Smart Choice

U.S. wild-caught butterfish is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.

Stock Structure

According to the 2024 stock assessment, butterfish is not overfished and not subject to overfishing. Summary stock assessment information can be found on Stock SMART. Scientists at NOAA’s Northeast Fisheries Science Center survey the abundance of butterfish off the East Coast.

Population

The stock is not overfished.

Fishing Rate

Not subject to overfishing.

Habitat Impacts

Fishing gears used to harvest butterfish have minimal impacts on habitat.

Bycatch

Regulations limit possession of bycatch species and require modified fishing gear to reduce bycatch.

Management

NOAA Fisheries and the Mid-Atlantic Fishery Management Council manage the butterfish fishery. Managed under the Atlantic Mackerel, Squid, and Butterfish Fishery Management Plan : Fishermen must have a permit to harvest butterfish. Managers limit the amount of available permits to control harvests. Annual catch limits are in place to prevent overfishing.
