What is the scientific name of a yellow fish perch?

There isn't a single fish species universally recognized as a "yellow fish perch". This name could refer to several different species depending on the location.

To accurately identify the specific fish, you need to provide more information, such as:

* Location: Where was the fish found (country, lake, river)?

* Appearance: What is the fish's size, shape, and any other distinguishing features?

* Habitat: Where was the fish found (freshwater, saltwater, etc.)?

Once you provide more details, I can help you narrow down the possibilities and find the correct scientific name.
