Distinguishing Features: Endemic to the Euphrates and Tigris river basins.
Conservation Status:
Data Deficient (DD)

Information regarding a specific IUCN redlist status is difficult to locate, but it is known to be under local protection.
The Tigris Trout (Salmo tigridis), a unique and recently identified species, is native to the Çatak Stream in the Tigris River drainage of Turkey. Known for its striking greenish body coloration and small, ocellated black and red spots, this trout stands out due to its deeper and stouter caudal peduncle, as well as a greater number of scale rows compared to other trout species in the region. Its short head and maxillary structure further distinguish it, making it a fascinating subject for researchers and conservationists alike.
Salmo tigridis thrives in the clear, fast-flowing waters of the Çatak Stream, where stone and pebble substrates create an ideal habitat. However, its survival is increasingly threatened. Despite this, reports and catches have declined sharply in recent decades, suggesting that overfishing and environmental changes are taking a toll on its populations. This alarming trend highlights the urgent need for further research and conservation measures to protect this unique trout.
As both a natural treasure and an indicator of the health of its environment, the Tigris Trout highlights the need for a balanced approach to conservation and recreation. If you eager to experience its habitat firsthand, this unique fish continues to captivate those who encounter it in the heart of Türkiye’s historic rivers.
Regulations and Ban
Regulations may exist due to overfishing concerns.
The discovery of Salmo tigridis underscores the rich biodiversity of Türkiye’s freshwater ecosystems, but it also serves as a reminder of the fragility of these habitats. As human activities and environmental changes continue to impact rivers and streams, protecting species like the Tigris Trout becomes essential for maintaining ecological balance.
Despite its distinct characteristics, the Tigris Trout faces significant challenges, as its populations are believed to be declining due to overfishing and habitat pressures.
