Menhaden play a crucial role in the marine ecosystem, serving as a primary food source for larger fish, birds, and marine mammals. These fish are also significant for commercial purposes. They are harvested for their oil and meal, which are used in animal feed, dietary supplements, and various industrial products. The fishing of menhaden is regulated to ensure sustainable populations, reflecting their importance in both ecology and economy.
