Are Rio Grande Perch good to eat?

Answers:
"Guinea perch," one of the bass anglers called them. "Because they're speckled like the feathers of guinea fowl." Other nicknames include Texas cichlid, Texas bluespot and blue-spotted perch.
To my Mexican guide, they were mojarra de Norte. He took them home for his family to eat, proclaiming them "the best eating feesh in the lake."
Sounds like the Mexicans think they are grat. Try one!
