  • Abstract:
  • Dhurde Tal Wetland, located in the Saran district of Bihar, is an important seasonal floodplain ecosystem that supports a diverse ichthyofaunal community vital for sustaining local fisheries and ecological balance. A comprehensive field survey conducted in 2023 documented 21 fish species from this wetland, representing a wide range of ecological and economic significance. The major species recorded included Labeo rohita (Rohu), Catla catla (Catla), Clarias batrachus (Garayi), Puntius sophore (Pothiya), Mystus tengara (Tangra), Heteropneustes fossilis (Singhi), Anabas testudineus (Patya), Parambassis ranga (Glass fish), Glossogobius giuris (Brigade), Xenentodon cancila (Golden fish), Notopterus notopterus (Barari), Wallago attu (Dara), Cirrhinus reba (Rewa), Gudusia chapra (Nayani), Macrognathus aral (Kevyi), Mystus cavasius (Bangur), Salmostoma bacaila (Dhalo), Rasbora daniconius (Kholsa), Chanda nama (Nekti), Macrobrachium rosenbergii (Jhinga - freshwater prawn), and Ompok bimaculatus (Tangusi). These species encompass commercially valuable carps, catfishes, small indigenous species (SIS), and predatory fishes, highlighting the ecological richness and trophic complexity of Dhurde Tal. Economically important species such as Catla catla, Labeo rohita, and Wallago attu dominate the commercial fisheries, while smaller species like Puntius sophore, Parambassis ranga, and Macrognathus aral maintain the ecological stability of the wetland. However, habitat degradation due to siltation, overfishing, and agricultural runoff poses serious threats to this biodiversity. Immediate conservation efforts including wetland restoration, community-based fishery management, and sustainable utilization strategies are urgently required to protect the ichthyofaunal diversity of Dhurde Tal Wetland. The data generated in this study provide an essential baseline for future biodiversity monitoring and sustainable fisheries development in floodplain ecosystems (Jayaram, 2010; Talwar & Jhingran, 1991; Lakra et al., 2010; Sarkar et al., 2017; Dahanukar et al., 2012).
