What is it when you eat meat but not fish?

However, you could describe them as:

* A meat-eater who avoids fish: This is a straightforward and accurate description.

* A non-pescatarian: This is a bit more technical, as "pescatarian" specifically describes someone who eats fish but not other meat.

* Someone who follows a diet that excludes fish: This is a broader description that could encompass various dietary reasons.

It's important to note that people may have various reasons for not eating fish, including ethical, religious, environmental, or health reasons.
