UNAIR NEWS – Dr. Veryl Hasan SPi MP, a lecturer from the Faculty of Fisheries and Marine Sciences (FPK) Universitas Airlangga (UNAIR), has contributed to the discovery of a new fish species on the island of Kalimantan. Together with an international research team, Dr. Hasan identified Kapuasia falaris, a previously unknown fish species, in the Barito River in Central Kalimantan.
Cross-national collaboration
The study, which led to the discovery of this unique fish, was conducted in collaboration with Maurice Kottelat from Switzerland and Lee Kong Chian of the National University of Singapore. The team dedicated approximately a year to research and species identification.
Dr. Hasan shared with UNAIR NEWS the critical involvement of local communities in the project. “This collaboration involved researchers from Singapore and Switzerland. Moreover, the assistance of local residents was crucial in acquiring the fish. During our expedition, local communities helped guide us,” he explained.
Kapuasia falaris discovery
Dr. Hasan further elaborated that the fish was previously unclassified and grouped with similar species. “Upon observation and analysis, we found distinct characteristics that set this fish apart, particularly the prominent white marking on its snout. This feature necessitated its reclassification,” he stated.

The fish was officially named Kapuasia falaris on December 2, 2024. Its name derives from Greek, meaning ‘white nose,’ referencing its most distinctive feature. “This species stands out because of its solid white snout, unlike related species with patterned noses,” said Dr. Hasan, who is also listed among the World’s Top 2% Scientist 2024 by Stanford University and Elsevier.
Impact of discovery
Kapuasia falaris is found only in specific water systems in Kalimantan, underscoring the ecological uniqueness of its habitat. “This discovery highlights the critical importance of preserving such ecosystems. The habitat is irreplaceable, and the justification for its protection is strong,” emphasized the aquaculture expert.
Dr. Hasan emphasized that this discovery not only enhances biodiversity but also has the potential to influence policies for species protection.
“This fish has already been part of the ornamental fish trade, albeit unnamed. Now that it has been formally identified—essentially given an ‘ID’—we can establish regulations. For instance, it might be prohibited from commercial trade. This formal recognition has broader systemic impacts,” he explained.
Dr. Hasan concluded by emphasizing the broader impact of the discovery, which highlights the need for further research and action. “This finding underscores the importance of legitimizing the existence of certain species to facilitate conservation, captive breeding, and sustainable management,” he concluded.
