Tuna vs. Tunas: Which one to use?
The English language provides two options for the plural form of this popular fish. Understanding when to use each will help you sound more natural and precise in your writing.
The “Zero Plural” Rule for Fish
In English, many names for fish follow the “zero plural” or “invariant plural” rule. This means the singular and plural forms are identical. Just as we say “one sheep” and “ten sheep,” we typically say “one tuna” and “a school of tuna.”
| Singular | Plural (Standard) | Context |
|---|---|---|
| Tuna | Tuna | A group of the same fish or the food product. |
| Salmon | Salmon | Standard plural for most fish. |
| Cod | Cod | Standard plural for most fish. |

While “tuna” is the most common plural form, tunas is frequently used by marine biologists, fishermen, and researchers. This specifically happens when they are discussing various types of tuna species collectively.
