What do cod fish eat?

Cod fish are opportunistic predators, meaning they eat whatever is available and most appealing to them. Their diet varies depending on their size and location but generally includes:

Smaller cod:

* Zooplankton: Tiny crustaceans and other small organisms in the water column.

* Crustaceans: Shrimp, crabs, and other small invertebrates.

* Small fish: Sandeels, herring, and other small fish species.

Larger cod:

* Larger fish: Haddock, pollock, and other larger fish species.

* Squid: A common prey for larger cod.

* Other invertebrates: Worms, jellyfish, and other benthic organisms (those living on the seafloor).

They also eat:

* Echinoderms: Starfish, sea urchins, and other spiny-skinned animals.

* Mollusks: Clams, mussels, and other soft-bodied invertebrates.

Cod are known to hunt in groups, especially when pursuing larger prey like herring or squid. They also exhibit cannibalistic behavior, occasionally eating smaller cod.

Overall, cod are versatile eaters and play an important role in the marine ecosystem.
