Restoring Ecological Harmony: The Transition From African Magur to Indigenous Fish Farming in Kheyadaha Wetland, India

The Kheyadaha Wetland, located in the eastern suburbs of Kolkata, West Bengal, India, known for its rich biodiversity, has faced severe threats from invasive alien fish species (IAFS) such as Clarias gariepinus, disrupting the ecosystem and impacting local livelihoods. A comprehensive survey from April 2022 to September 2023 identified ten main IAFS, highlighting their detrimental effects on native species through competition and predation. This study addressed these challenges by promoting sustainable aquaculture practices, transitioning farmers from cultivating invasive species to indigenous fish like Indian major carps. The project incorporated low-cost fish feed production, value-added products, and market linkages, significantly increasing farmers' annual income. Community engagement through training, awareness programs, and capacity-building initiatives fostered a shift towards indigenous species cultivation, enhancing biodiversity conservation and economic resilience. The project's success underscores the importance of interdisciplinary collaborations and evidence-based policy formulation in invasive species management. By empowering local communities and promoting sustainable practices, the project serves as a model for effective biodiversity conservation and sustainable livelihoods in wetland ecosystems. Continued investment in such initiatives is crucial for safeguarding ecological integrity and economic sustainability, ensuring long-term resilience and environmental harmony in wetland regions.
