Résumé :
|
The Iranian part of the Caspian Basin, a vital habitat for 87 native fish species, faces various anthropogenic threats. To effectively conserve its fish biodiversity, understanding the current conservation status of these species is crucial, especially since the last assessment occurred 25 years ago and identified 12 species as threatened. This study updates the conservation status of these fishes using the IUCN Red List Criterion A thresholds at regional, national, and local levels. The results indicate that 20 fish species in the region are now threatened, with 10% Critically Endangered, 7% Endangered, and 6% Vulnerable. This represents a significant increase compared to the previous assessment and highlights the urgent need for conservation action. Many of the threatened species are migratory or economically valuable, making them particularly vulnerable. The key threats include unsustainable fishing practices, pollution, habitat degradation, and climate change. By taking proactive and ecosystem-based steps to mitigate these threats based on the updated data of the fish species’ status and prioritizing the conservation of threatened species, the future of these fish fauna can be secured.
