Creole Perch vs Puye: common questions
Which fish has the more unusual distribution?
The puye does, found not only in southern South America but also in New Zealand and Australia, an extraordinary range for such a small fish, while the creole perch is native specifically to Patagonia.
Which fish is more threatened by introduced species?
The creole perch is, increasingly displaced in parts of its range by introduced trout and salmon stocked for sport fishing, a pressure not significantly documented for the puye.
Do both fish migrate between rivers and the sea?
No, only the puye does, moving between freshwater rivers and the ocean at different life stages, while the creole perch remains in freshwater throughout its life.
