Taxonomical Status of Endemic Fishes of Northeast India: A Fish Biodiversity Hotspot in the World

Nestled amidst the grandeur of the mighty Himalayas, Northeast India emerges as a realm of unique biodiversity in its flora and fauna. This study presents findings encompassing 414 species across 99 genera and 25 families, denoting a remarkable diversity within the region. Notably, the report excludes widely distributed species, concentrating instead on those exclusive to specific basins, highlighting the region's distinctiveness. Emphasizing the significance of integrative taxonomy, the report underscores the limitations of relying solely on morphology, as it sometimes fails to capture the distinguishing characteristics among different species. The notion that species can differ in identity while sharing strong similarities poses challenges within morpho-taxonomy. However, these enigmatic situations have often found resolution through molecular studies. Additionally, recognizing the importance of investigating the histology and biology of specific cultivable species is crucial. Undoubtedly, a collaborative approach involving biologists and taxonomists holds the potential to significantly enhance our understanding of the region's diversity. The report also provides the IUCN statuses of certain fish species, further contributing to the comprehensive understanding of the area's ecological landscape.
