Small indigenous fish species are rich in essential micro-nutrients that can help tackle micronutrient deficiencies globally. They are the key regulator of Kaptai Lake fishery, the largest man-made lake in Bangladesh. Though small indigenous fish species are indispensable for meeting the animal protein demand and livelihoods of small-scale fisheries of Kaptai Lake, detailed studies about this sector are lacking. This chapter investigates the biodiversity and conservation status of small indigenous fish species and their threats and subsequent impacts on small-scale fisheries. A total of 49 small indigenous fish species were recorded from the lake, and the majority of them (61%) fall under ‘least concerned’ category according to the IUCN Red list. However, pollution, habitat destruction, siltation, climate change, overexploitation, and extreme fishing pressure were identified as major causes that lower fish production capacity and pose threats to the biodiversity of the small indigenous fish species in the lake. Better management strategies such as protection of natural breeding grounds, controlled pollution, proper implementation of fishing laws, scientific fishing policies, and integrative research could ensure sustainable management and conservation of these fish in the Kaptai Lake. These findings will be helpful in planning and accomplishing proper lake management strategies for the wellbeing of the ecosystem and connected small-scale fishers.
