First Comprehensive Assessment of Fish Diversity in the Trang An Scenic Landscape Complex, Ninh Binh Province, Vietnam

A first-of-its-kind study documents 41 fish species—spanning 8 orders, 17 families, and 33 genera—in the UNESCO-listed Trang An Landscape Complex, Vietnam. Among them, 12 were previously unrecorded in the Red River’s ichthyofauna, while biodiversity metrics (Shannon-Wiener index H′: Fair to Very Good; species richness d) revealed a remarkably even distribution across four key areas. The research also flags marine/brackish-water intruders and exotic invaders with potential ecological consequences. Conducted via four 2024 surveys at 20 sites, this work establishes a critical baseline for monitoring, conservation planning, and sustainable ecotourism in the World Heritage Site.
