Percichthys melanops, also known as the black perch, is a special type of fish found only in Chile. It lives in streams that flow down from the Andes mountains. This fish can grow up to about 20 centimeters (almost 8 inches) long. It was first described by a scientist named Charles Frédéric Girard in 1855.

About the Black Perch
The black perch is a fascinating fish that belongs to a group called temperate perches. It's known for its unique appearance and its specific home in the cool, clear waters of Chilean streams.
What Does It Look Like?
The Percichthys melanops gets its common name, black perch, from its often dark coloring. While its exact shades can vary, it usually has a somewhat dark body, helping it blend in with the rocky bottoms of its stream habitat. It has fins typical of a perch, designed for swimming in flowing water. Its size, up to 20 centimeters, makes it a medium-sized freshwater fish.
Where Does It Live?
This fish is an endemic species, which means it naturally lives only in one specific place in the world. For the black perch, that place is Chile. It prefers the pre-Andean streams, which are rivers and creeks that come from the Andes mountains. These streams usually have clear, cool water and rocky or gravelly bottoms, providing good places for the fish to hide and find food.
What Does It Eat?
Like many freshwater fish, the black perch is likely a predator. It probably eats smaller aquatic insects, their larvae, and possibly other tiny creatures found in the streams. Its diet helps keep the stream ecosystem balanced.
Life Cycle and Reproduction
Fish like the black perch have interesting life cycles. They usually lay eggs, which hatch into tiny fish called fry. These fry then grow into juvenile fish and eventually into adults. The specific details of the black perch's reproduction, like when and where it lays eggs, are still being studied by scientists.
Conservation Status
The Percichthys melanops is listed as "Data Deficient" (DD) by the IUCN. This means that there isn't enough information available about the fish's population or threats to its survival. Scientists need more research to understand how many black perch are left and what might be affecting them.
Why is "Data Deficient" Important?
When a species is "Data Deficient," it doesn't mean it's safe. It means we don't know if it's in danger or not. This lack of information makes it hard to create plans to protect the fish and its habitat. It's important for scientists to study these species so we can make sure they continue to thrive in their natural homes. Protecting their stream habitats is key to their survival.
