Magur Fish (Clarias Batrachus) Found in Koshi River, Supaul: A Comprehensive Research Study

Country India
Abstract Magur fish (Clarias batrachus), an economically vital air-breathing catfish species, represents a cornerstone of freshwater aquaculture in Bihar, particularly in the Koshi River watershed region of Supaul district. This comprehensive research paper synthesizes current scientific evidence regarding the distribution, biology, aquaculture potential, and conservation challenges of Magur fish in this critical ecosystem. The study integrates field investigations of Koshi River ichthyofaunal diversity, breeding and reproduction protocols validated in Bihar hatcheries, nutritional requirements, and ecosystem-level considerations. The Koshi River at Supaul supports diverse fish fauna comprising 25 species across 8 families, with demonstrated potential for integrated fish farming systems combining Magur with rice cultivation and livestock production. Current hatchery infrastructure in Bihar operates at 700 million annual seed production capacity, driven by government investment through the Pradhan Mantri Matsya Sampada Yojani (PMMSY) and Prime Minister Special Package schemes. However, wild Magur populations face critical conservation challenges including genetic erosion from hybridization with exotic African catfish (Clarias gariepinus), declining genetic diversity, and habitat degradation from pollution and wanton fishing practices. This paper presents evidence-based recommendations for sustainable Magur aquaculture in the Koshi River region, emphasizing conservation of wild populations, optimization of hatchery protocols, nutritional management aligned with regional feed availability, and integrated farming approaches supporting rural livelihoods and food security. Implementation of these science-based strategies will strengthen Bihar's aquaculture sector while ensuring long-term viability of this culturally and economically significant species.
