Pethia manipurensis is an endemic and endangered freshwater fish of Loktak Lake, Manipur, with recognised local food, medicinal, cultural and potential ornamental value. The species is perceived by local communities to be declining, but community-based documentation of its traditional uses, perceived threats and conservation needs remains limited. This study documented local ecological knowledge of P. manipurensis through a questionnaire-based survey conducted during 2024-2025 at multiple sites around Loktak Lake. A total of 100 respondents, including fishers, fish vendors, farmers, women involved in fish processing and community elders, were interviewed using a semi-structured questionnaire. Data were analysed using descriptive statistics and presented as frequencies and percentages. Most respondents were aged 20-70 years (60%), and women constituted 70% of the sample. All respondents perceived a decline in the abundance of P. manipurensis, while 70% reported that the species had formerly been available in large quantities but is now found only in very small quantities. Ecosystem changes (50%) and pollution (40%) were identified as the main perceived causes of decline. The species was reported as a traditional food fish, commonly prepared by boiling and frying, and drying was the main preservation method. Respondents also reported ethno-medicinal use for laryngitis and dysentery, along with cultural importance. Conservation support was high, with respondents emphasising awareness programmes, government plans and scientific research. The findings indicate that community knowledge can provide useful baseline information for future ecological studies and conservation planning. Further field-based population assessment, habitat evaluation and validation of reported medicinal uses are required to support evidence-based conservation of P. manipurensis.
