Forage fish may be small, but they help hold the ocean food web together. Species like sardines, anchovies, herring, capelin, and sand lance feed whales, seabirds, salmon, cod, tuna, and many other predators.

In this episode of  How to Protect the Ocean , Andrew Lewin explains why fishing these small fish for fishmeal, fish oil, aquaculture feed, livestock feed, pet food, and supplements can create major ripple effects across marine ecosystems.

The big question is not only whether forage fish populations can survive fishing pressure. It is whether the ocean can survive losing too much of the food that keeps predators alive.
