Forage fish are small fish species that serve as a crucial food source for larger predators, including tuna, seabirds, and marine mammals. Common examples of forage fish include anchovies, sardines, and herring. They typically inhabit coastal waters and are known for their high reproductive rates, which help sustain their populations despite heavy predation. These fish play an essential role in marine ecosystems by transferring energy from primary producers, like plankton, to larger fish and wildlife. Forage fish are also important for commercial fishing industries, as they are often harvested for use in fishmeal and as bait for larger fish species.
