Project to Protect Brown Trout Paying Dividends

The population of brown trout species, endemic to Haraz River in Mazandaran Province, was successfully protected against the invasive rainbow trout thanks to a project spearheaded by the Department of Environment.
As the first joint environmental pilot scheme, local NGOs namely Larkouh and Recreational Fishers Community assisted the DOE in a task that has so far produced favorable results, DOE's news portal reported.  
Years ago, the practice of rainbow trout farming initiated along the river, but accidentally, the species made its way into the river and rapidly started to reproduce. Grabbing bigger preys, the non-native fish made natural food less available for the endemic types, making them more vulnerable to extinction.  
To take control of the situation, the local environmental communities suggested the gradual elimination of the invasive species through adopting an eco-friendly strategy.
