    Assessment of fish species and migratory aquatic birds’ biodiversity in Yamuna river (Haryana)
    (CCSHAU Hisar, 2022-07) Yadav, Shri Ram; Ravikant
    The study was conducted to assess the fish diversity and migratory aquatic birds in the Yamuna river at selected sites. The fish and migratory aquatic birds were monitored from September 2021 to April 2022. The 64 fish species belonging to seven orders and 17 families and 59 bird species belonging to eight orders and fourteen families were recorded in the present investigation. Cypriniformes order and Cyprinidae family were found to be the most dominant. Indian major carp, along with exotic carps and Wallago attu, contribute a significant portion of the fish catch of the Yamuna river in the studied sites. The Order Charadriiformes was dominant, containing 31 per cent of bird species. The family Anatidae was found to be dominant, including 25 per cent of bird species. Out of 59 bird species, 33 species were winter migrants, 16 species were residents, and ten species were local migrants. The twenty-four bird species were very common; 20 were common, eight were rare, and seven were less common in the study area, and out of total bird species, 50% were found to be Least concern (LC). The 17 genera of phytoplankton belonging to four major groups were recorded. Out of 19 genera of zooplankton population, nine genera belonged to (Copepoda), two genera (Rotifera), four genera (Cladocera), and two genera (Protozoa ) recorded. The physicochemical water quality parameters during the present investigation were recorded at the poorest level in April in the Faridabad riverine system. The present study gives enlightening information on fish bio-diversity and assists in understanding the water nature of the Yamuna river. Fish –biodiversity is an indicator of ecosystem health, conservation status and human food resources. The fish biodiversity of the Yamuna river was poor, indicating its water quality. There is a need of the hour to conserve the vulnerable and endangered fauna of the Yamuna river through suitable conservation strategies.
