Forage fish are small species such as herring, menhaden, and sardines that swim in big schools and feed on plankton. Though tiny, forage fish play a massive role in our ocean's ecosystem, serving as a critical food source for species ranging from sharks and whales to seals and seabirds.
Watch and learn how the littlest fish make a big difference, and how fisheries leaders can help protect populations from overfishing.
