Is halibut fish a scavenger

A scavenger is an animal that feeds on dead and/or decaying organisms. A halibut fish, however, typically feeds on plankton during its first year of life, whereas at two or three years of age, they begin to feed on euphausiids (small shrimp-like organisms) and small fish. As halibut grow, fish make up a larger part of their diet. Besides pollock, sablefish, cod, and rockfish, large halibut also eat octopus, herring, crabs, clams, and smaller halibut.

Therefore, the answer is no. A halibut is not a scavenger.
