They play a significant role in the ecological food web because they feed on small fish. Subsequently, the large fish feed on herring as a cycle of the food web.

That said, herring enjoy feeding on various small fish and crustaceans. Dive into their diet to learn more about “what do herring eat?”

Insects, Animals, and Fish

Cruising with their schools in the shallow water, herring prey on fish that pass by them. Exhibiting the ram feeding behavior, the school of herrings feeds on minuscule fish with their mouths wide open.

Herring eat copepods, amphipods, tiny fish, mysids, shrimp, krill, and other small aquatic creatures. Plus, herring eat fish eggs, fish larvae, molluscan larvae, pteropods, menhaden larvae, and snail larvae.

When they dive deep at the bottom, herring can adapt to filter-feeding behavior. Hence, herring eat zooplankton available in abundant amounts in the water.

Along with consuming fish, herring eat insects if the opportunity presents itself. Hence, the staple food of herring includes various microorganisms.

Fruit, Vegetables, and Plants

While these fish stick to consuming other small fish, herring forage on plants as well. However, they do so in moderation because they aren’t fond of feeding on plants specifically.

But as schooling herring cruise with their mouth open in the open water, they feed on whatever crosses their path. That said, herring eat plants, algae, seaweed, and phytoplankton. Herrings also consume diatoms and other microscopic plant-based diets if other food items are scarce items.

What herring don’t eat?

Herrings can’t feed shellfish, but they do prey on their larvae and eggs occasionally. Herrings don’t eat sea urchins, crabs, or sharks no matter how appetizing they may seem.
