Researchers at the University of the South Pacific (USP) have made a significant discovery, identifying a new species of ray called the Fiji maskray (Neotrygon romeoi), which is found exclusively in the waters surrounding Fiji. This research, led by Dr. Kerstin Glaus and published in the Journal of Fish Biology on June 9, 2025, highlights the unique biodiversity that exists within the region.
The Fiji maskray is part of the blue-spotted maskray complex and had previously been mistaken for closely related species. Dr. Glaus’s research team utilized detailed morphological measurements, vertebral counts, and DNA barcoding techniques—similar to product barcodes—to confirm the ray’s distinct identity. Dr. Glaus noted the ray’s distinctive features, such as its broad snout, elongated claspers in adult males, and its characteristic thorn-like spines running along its body.
Moreover, the Fiji maskray plays a crucial role in local fisheries and is often traded in markets across the islands. Dr. Glaus emphasized the importance of conservation, advocating for the species’ inclusion in Fiji’s Endangered and Protected Species Act to regulate trade and protect this unique ray as it is among the many marine organisms that face threats, including overfishing and habitat destruction.
The discovery of the Fiji maskray underscores Fiji’s rich natural heritage and stresses the urgent need for conservation efforts to protect marine species. Lavenie Tawake, a USP project team leader, reflected on the significance of this finding, noting the necessity of safeguarding Fiji’s marine biodiversity.
This new identification aligns with ongoing conservation efforts and workshops aimed at addressing the challenges facing marine life, including those targeting sharks and rays held recently at USP. Such initiatives, made possible through collaborations like the Pacific-European Union Marine Partnership (PEUMP), are crucial for enhancing awareness and building capacity for marine conservation.
The dedication and research of the USP team, coupled with community involvement, offer hope for the sustainable management of marine resources in Fiji. By prioritizing conservation, Fiji can continue to protect its unique marine ecosystems for future generations.
