Menhaden: Key Species in Atlantic Fisheries and Marine Ecosystems

Menhaden, sometimes referred to as "pogy," "bunker," or "mossbunker," are a group of four species of fish found in the Western Atlantic, from Nova Scotia to Brazil. These fish belong to the genera Brevoortia and Ethmidium within the Clupeidae family, which includes other well-known fish like herring. Menhaden play a crucial role in the marine ecosystem as they feed on microscopic plants and animals, filtering the water as they swim in large schools near the ocean's surface.

Menhaden are primarily harvested using purse seines, a method ideal for capturing large schools of fish near the surface. Once caught, these fish are either stored in non-refrigerated holds, requiring them to be brought to port within 24 hours, or kept in refrigerated holds, allowing vessels to remain at sea for several days. Despite their abundance, menhaden are not consumed directly by humans. Instead, they are processed into fish meal and oil, much like herring. These by-products are essential for various industries, particularly in agriculture, where fish meal serves as a high-protein feed for livestock and aquaculture, and fish oil is used in supplements and industrial applications.

In the United States, menhaden are the most heavily harvested fish, with annual catches amounting to several hundred thousand metric tons. This makes them one of the most significant fisheries by volume in the country. The sustainability of menhaden fisheries is closely monitored due to their ecological importance. These fish are a vital food source for larger predators like striped bass, bluefish, and marine mammals, and their filtration activity helps maintain the health of coastal waters. Consequently, maintaining balanced harvest levels is crucial to preserving both the menhaden population and the broader marine ecosystem they support.

Menhaden
Four species of menhaden, sometimes called “pogy,” “bunker,” or “mossbunker,” are found in the Western Atlantic. They are fish of the genera Brevoortia and Ethmidium, two genera of marine fish in the family of Clupeidae.

They range from Nova Scotia to Brazil. Menhaden feed on microscopic plants and animals.

They are caught with purse seines when schooling near the surface of the water and removed to the hold of the power boat or carrier vessel. Aboard the boat, they may be held without refrigeration, in which case they will be brought to port within a period of 24 hrs after catching. Boats that keep these fish in refrigerated holds may remain at sea for several days prior landing the catch.

Menhaden are not used for human food. They are processed to produce fish meal and oil in the manner described for herring. In the United States, larger quantities of menhaden are caught (several hundred thousands metric tones) than that of any other fish or shellfish.
