Abstract: Osteobrama belangeri, a minor carp locally known as "Pengba?, is an endemic and highly esteemed fish species in Manipur, India. While once a significant component of the state's natural fisheries, its wild population has faced a severe decline, leading to its designation as "extinct in the wild" in Manipur. This has spurred a considerable effort to promote its aquaculture, particularly in the valley areas of Imphal. The success of these rearing efforts is intrinsically linked to the region's agro-climatic conditions. This review paper synthesizes existing literature to analyze the multifaceted impact of agro-climatic factors, including temperature, rainfall, and water quality, on the growth, breeding, and overall productivity of Pengba culture. It explores how seasonal variations and a changing climate influence the species' feeding habits, breeding cycles, and susceptibility to diseases. The paper also discusses the challenges and opportunities presented by these factors, highlighting the need for climate-resilient aquaculture practices to ensure the sustainable conservation and commercialization of this culturally and economically important species.
