Is there a fish called poor cod?

There is no fish species known as "poor cod". However, there are several fish species that have names that sound similar, such as the Patagonian toothfish (sometimes referred to as "Chilean sea bass" or "poor man's lobster") or the cusk-eel (also known as "poor man's lobster"). These names are typically used in commercial settings or by fishermen, and may vary regionally.
