Menhaden, also known as mossbunker, and bunker, are forage fish of the genera Brevoortia and Ethmidium, two genera of marine fish in the family Clupeidae. Menhaden is a blend of poghaden (pogy for short) and an Algonquian word akin to Narragansett munnawhatteaûg, derived from munnohquohteau ‘he fertilizes’, referring to the fish's use as fertilizer.[1] It is generally thought that Pilgrims were advised by Tisquantum (also known as Squanto) to plant menhaden with their crops.[1]


Menhaden are flat, have soft flesh, and a deeply forked tail. They rarely exceed 15 inches (38 cm) in length, and have a varied weight range. Gulf menhaden and Atlantic menhaden are small oily-fleshed fish, bright silver and characterized by a series of smaller spots behind the main, Humeral spot. They tend to have larger scales than Yellowfin menhaden and Finescale menhaden. In addition, Yellowfin menhaden tail rays are a bright yellow in contrast to those of the Atlantic menhaden.

Recent taxonomic work using DNA comparisons have organized the North American menhadens into large-scaled (Gulf and Atlantic menhaden) and small-scaled (Finescale and Yellowfin menhaden) designations.[2]

The menhaden consist of two genera and seven species:


  • The various species of menhaden occur anywhere from estuarine waters outwards to the continental shelf. Menhaden grow in less saline waters of estuaries and can be found in bays, lagoons, as well as river mouths. Adults appear to prefer water temperatures near 18 °C.


Menhaden travel in large, slow-moving, and tightly packed schools with open mouths. Filter feeders typically take into their open mouths "materials in the same proportions as they occur in ambient waters".[3] Menhaden have two main sources of food: phytoplankton and zooplankton. A menhaden’s diet varies considerably over the course of its lifetime, and is directly related to its size. The smallest menhaden, typically those under one year old, eat primarily phytoplankton. After that age, adult menhaden gradually shift to a diet comprised almost exclusively of zooplankton.[4]

Menhaden are omnivorous filter feeders, feeding by straining plankton and algae from water. Along with oysters, which filter water on the sea bed, menhaden play a key role in the food chain in estuaries and bays.[5] Atlantic menhaden are an important link between plankton and upper level predators. Because of their filter feeding abilities, "menhaden consume and redistribute a significant amount of energy within and between Chesapeake Bay and other estuaries, and the coastal ocean."[6] Because they play this role, and their abundance, menhaden are an invaluable prey species for many predatory fish, such as striped bass, bluefish, mackerel, flounder, tuna, Drum (fish), and sharks. They are also a very important food source for many birds, including egrets, ospreys, seagulls, northern gannets, pelicans, and herons.

In 2012 the Atlantic States Marine Fisheries Commission declared that the Atlantic menhaden was depleted due to overfishing. The decision was driven by issues with water quality in the Chesapeake Bay and failing efforts to re-introduce predator species, due to lack of menhaden on which they could feed.[1]

Human intake[edit]

Menhaden are not used directly for food. They are processed into fish oil and fish meal that are used as food ingredients, animal feed, and dietary supplements.[5] Fish oil made from menhaden is also used as a raw material for products such as lipstick.[7]

According to James Kirkley of the Virginia Institute of Marine Science (VIMS), there are two established commercial fisheries for menhaden. The first is known as a reduction fishery. The second is known as a bait fishery, which harvests menhaden for the use of both commercial and recreational fishermen. Commercial fishermen, especially crabbers in the Chesapeake Bay area, use menhaden to bait their traps or hooks. The recreational fisherman use ground menhaden chum as a fish attractant, and whole fish as bait. The total harvest is approximately 500 million fish per year.[7] Atlantic menhaden are harvested using purse seines.

Omega Protein Inc., Houston, Texas, with operations in Virginia, Louisiana, and Mississippi takes 90% of the national total menhaden harvest.[7] In December 2012, in the face of the depletion of Atlantic menhaden, the Atlantic States Marine Fisheries Commission imposed a limit on Omega's operations, "capping the total annual commercial catch at 170,800 metric tons, about 80 percent of the average harvest from the last three years."[9]
