Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Effect of different salinity on growth, survival and hematology of Amur carp
    (CCSHAU, Hisar, 2021-07) Nikki; Ahalavat, Shikha
    Effect of different salinity on growth, survival and hematology of Amur carp, Cyprinus carpio haematopterus (Linnaeus, 1758) was evaluated in a 60 days experiment. Three hundred fingerlings having average weight 8.38 ± 0.04 g, were equally distributed in 5 treatment groups: Control (0 ppt), T1 (3 ppt), T2 (6 ppt), T3 (9 ppt) and T4 (12 ppt) with 3 replicates in 500 L FRP tanks followed by complete randomized design (CRD) after acclimatization. The behavioural changes like swimming activity and appetite changes were observed in 9 ppt and 12 ppt during the experiment. The maximum survival rate was recorded in control with 100 % survivability while minimum in 9 and 12 ppt. There were no significant differences observed in water parameters like pH, Temperature and Dissolved Oxygen (DO) while parameters like ammonia, nitrite, TDS (Total Dissolved Solute) and conductivity increase significantly with increase in salinity of water. Fish growth (ADG, SGR and TWG) decline significantly (P≤0.05) from control to T4 respectively while FCR increase significantly with increase in salinity. Due to salinity stress there was significantly increase in haematological parameters including RBC, WBC, PCV and Hb. Significant changes in biochemical parameters of blood also occurs under different salinity. There was significantly decline in serum glucose level (P≤0.05) while significantly increase in Alkaline phosphatase (ALP), Aspartate amino Transferase (AST) and Alanine amino Transferase (ALT) level. The results suggested that Amur carp (Cyprinus carpio haematopterus) can be cultured ≤ 6 ppt most probably upto 5 ppt.
