| Abstract | ||||
| The genus Hemiscyllium, commonly known as “Hiu Berjalan” (walking sharks), comprises nine species which are mostly endemic to Indonesia and Papua New Guinea, with a restricted geographic distribution. This study evaluated the status, limitations, and challenges of Hemiscyllium research in Indonesia through a bibliometric approach, based on 88 Scopus-indexed publications (1993–2024) analyzed using Biblioshiny (bibliometrix v4.3.0) and VOSviewer 1.6.19. Results indicate a moderate annual publication growth rate of 3.61%, with 46.59% involving international collaboration, but relatively low participation of Indonesian researchers. Temporal and thematic mapping showed that research was concentrated in the period 2015–2023, predominantly focusing on physiological adaptations to hypoxia in H. ocellatum, while ecological, population, and conservation studies remained limited. Geographical analyses highlighted a strong concentration of research in eastern Indonesia (Halmahera, Raja Ampat, and Cenderawasih Bay), with western and central regions underrepresented. Taxonomic and disciplinary analyses revealed a predominance of single-species physiological studies, with limited integration into ecosystem or management contexts. Keyword mapping identified three main research clusters: stress physiology, habitat ecology, and species conservation. Current conservation mechanisms largely rely on marine protected areas and CITES listings, yet lack species-specific management strategies. These findings underscore the need to address research gaps, strengthen national scientific contributions, foster local–international collaborations, and integrate scientific evidence into targeted conservation policies for Hemiscyllium spp. in Indonesia. | ||||
