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.

    Survey, isolation and identification of bacterial diseases of fresh water fishes in district Hisar, Haryana
    (CCSHAU, 2005) Dahiya, Tejpal; Sihag, R.C.;
    The present investigation was carried out to identify fish pathogens causing fish diseases in catla, rohu, mrigal, common carp, puthi and magur. A number of biochemical tests were carried out for identification of bacterial fish pathogens. The bacterial diseases were identified viz. epizootic ulcerative syndrome, fin and tail rot, hemorrhagic septicemia and vibriosis in three selected fish farms (Mirka, Satrod and SLR, Hansi) from July 2004 to March 2005. These diseases were reported in July, August, October and November. No disease was found in September, December, January, Febuary and March. Ten gram negative ( Aeromonas hydrophila, Enterobacter cloacae, E. gergoviae, Pseudomonas sp., P. pseudomallie, Klebsiella pneumoniae subsp. aerogenes, Providencia sp., Serratia marcescens, Vibrio anguillarum, V. alginolyticus) and two gram positive (Micrococcus roseus, Streptococcus gp Q1) bacterial pathogens were identified from infected fishes. In EUS, fungal hyphae were found penetrating deep into muscles in catla. In fish farm of Satrod, vibriosis was reported in magur. The bacterial pathogens (Vibrio anguillarum, V. alginolyticus) were isolated from the skin lesions. These bacteria are generally found in marine, brackish and rarely in fresh water. Deviation of optimal range of hydrobiological parameters led to infection in fishes resulting in to disease outbreaks.
