    Ichthyofaunal diversity along with socio-economic status of farmers in Hisar District of Haryana
    (CCSHAU, Hisar, 2022-07) Yadav, Shankar Lal; Dahiya, Tejpal
    The study was carried out in the Hisar District, which is located in Haryana, India. Ichthyofaunal diversity along with socio-economic status of farmers in Hisar District of Haryana were monitored from October 2021 to March 2022. The recorded fish diversity revealed 12 fish species have been recorded from Hisar District which belongs to 4 orders, 7 families and 12 genera. In present investigation it is observed that 37.7% of fish farmers have fisheries as primary occupation and 52% farmers had an annual income between Rs. 3 to 4.5 lakh. The present study gives enlightening information on Ichthyofaunal diversity and socio-economic conditions of fish farmers of Hisar District.

    Assessment of plankton diversity and hydro biological parameters at selected sites of Yamuna river
    (CCSHAU, Hisar, 2023-07) Ambrish Singh; Ravikant
    The study was conducted to assess the plankton diversity and hydrobiological parameters at selected sites of Yamuna river. The plankton diversity and hydrobiological parameters were observed from June to November, 2022. The 96 genera of planktons recorded. Out of this 76 genera of phytoplankton recorded belonging to class Bacillariophyceae, Chlorophyceae, Cyanophyceae, Euglenophyceae, Dianophyceae and 20 genera of zooplankton were recorded belonging to Protozoa, Copepoda, Cladocera, and Rotifera have been identified in all the sampling sites during the study period. Shannon and Weaver diversity index for plankton was reported maximum in Tajewala barrage (1.984) followed by Wazirabad barrage (1.972) and Okhla barrage (1.871). The maximum temperature value recorded during pre-monsoon and minimum in the post-monsoon season was recorded in all the locations. The pH values of water in Tajewala, Wazirabad, and Okhla barrages were recorded from 7.3 to 8.4. The highest electrical conductivity values were observed in the Okhla barrage (1,527.25 μs/cm), followed by the Wazirabad barrage (1,227.75 μs/cm) and the Tajewala barrage (323.75 μs/cm). The DO levels ranged from 5.33 to 6.57 mg/L, 4.13 to 5.25 mg/L, and 1.7 to 3.6 mg/L. Salinity, free carbon dioxide, ammonia, TDS, Bicarbonates, nitrate, nitrite, chloride, calcium and magniseum varied at Tajewala, Wazirabad, and Okhla barrages at different times during the study period. The present investigation shows that the maximum level of presumptive coliform count recorded at Tajewala barrage maximum in November 2022 and lowest in September 2022. At Wazirabad, the barrage was recorded maximum in June and November, months. At Okhla barrage it was maximum recorded in November and lowest in July, August and September. This study revealed that the Tajewala barrage had the highest plankton diversity compared to Wazirabad and Okhla barrages. The water quality parameters measured, including temperature, pH, electrical conductivity, and dissolved oxygen levels, varied across the three barrages, indicating the potential influence of various factors such as industrial and municipal waste disposal and sewerage effluents.

    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.
