Forage Fish

Forage fish, also known as bait fish or prey fish, are small pelagic fish which are preyed on by larger predatory fish, marine mammals, and birds. They are in turn key predators of zooplankton and smaller benthic species.

Pronunciation

Forage fish: /ˈfɔːrɪdʒ fɪʃ/

Etymology

The term "forage fish" is derived from the act of "foraging" or searching for food, which these fish are known for. The term "bait fish" comes from their use as bait in fishing.
