Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Comparative assessment of performance of cryopreserved sperm of common carp to Amur carp
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-08) Sharma, Adita; Ram, R.N.
    The present study was conducted for comparing the performance of cryopreserved sperm of Common carp (Cyprinus carpio) with its Amur strain (Cyprinus carpio haematopterus) under tarai condition of Uttarakhand. The parameters used for milt quality analysis are sperm motility percentage and motility duration. Fertilization rate, hatching rate and embryonic development were also recorded in normal and late breeding season. Approximately hundred specimens of common carp and Amur carp were obtained from Instructional Fish Farm of College of Fisheries, Pantnagar. 40 specimens of mature common carp and Amur carp (1-1.5 kg body weight) in separate ponds were stocked. Carp were fed with conventional feed (rice bran: oil cake in 1:1 ratio) in wet form @ 1.5% body weight/day. Fishes were checked for milt availability by pressing the belly and those fishes oozed milt were taken for milt cryopreservation experiments. Water quality parameters (i.e. temperature, pH, dissolved oxygen, carbon di-oxide) had been recorded for the duration of the experimentation period in both ponds. Temperature and pH were recorded every day at morning and evening hours (7 am and 6 pm). Dissolved oxygen was determined by Winkler‘s method and free CO2 was determined by titration method once every week. Observations of I experiment are indicative of a successful cryopreservation of Amur carp and common carp sperm using either one of TRIS, RPMI1640 and PBS as extender with the addition of DMSO and Glucose collectively as cryoprotectant. The use of TRIS diluent with DMSO and Glucose was rated as the best combination for freezing common carp and Amur carp sperm. The formation of sperm agglutination in sperm is probable affected by extender composition, type of cryoprotectant and cooling conditions. For this reason, the use of TRIS, RPMI1640 and PBS with DMSO and Glucose for freezing Amur carp and common carp sperm in the liquid nitrogen vapour may additionally have paramount significance being a feasible protocol for captive breeding programme. In case of embryonic development, TRIS+DMSO+Glucose and PBS+DMSO gave satisfactory results. Observations of II experimentation indicate that successful cryopreservation of common carp and Amur carp sperm may be accomplished by using either TRIS, RPMI and PBS as extender and DMSO and Glucose as cryoprotectants. Among the different diluents, maximum motility percentage, motility duration, total sperm count, motile and non-motile sperm, fertilization rate and hatching rate were obtained in Amur carp with RPMI+DMSO in both the seasons. In case of common carp, the higher percentages of viability and fertilization rate were observed in PBS+ DMSO with respect to NBS and TRIS+DMSO+Glucose with respect to LBS. Therefore, the use of these dilutors for freezing in liquid nitrogen vapour may additionally have ideally suited significance being a viable protocol for captive breeding programme. Results of experiment III are indicative of successful cryopreservation of common carp and Amur carp sperms either by using TRIS+DMSO+Glucose or RPMI+DMSO or PBS+DMSO. In Amur carp comparison of three diluent combinations, maximum motility, fertilization rate and hatching rate were obtained with TRIS+DMSO+Glucose in both the seasons. In case of common carp, the higher percentages of viability and fertilization rate were observed in PBS+ DMSO during NBS and LBS. On the premise of this test, it can be concluded that TRIS+DMSO+Glucose is the best suited combination for freezing Amur carp sperm. On the other hand, PBS+DMSO is quality combination for freezing of common carp sperm. On the basis of investigated findings of this study it can be concluded that Amur carp shows good sperm motility percentage and duration as well as sperm count and motile sperm and less non-motile sperm. Fertilization and hatching rate and embryonic development are also higher than common carp in normal and late breeding season. The overall result of the present study revealed that in comparison between Amur carp and common carp, best embryonic development were found in Amur carp indicating that Amur carp performed well than common carp. It shows that there was significant difference being better in Amur carp. It indicating that reproduction capacity of Amur carp is higher than common carp. So, if Amur carp is cultured on large scale, a high profit will be obtained which will augment fish production. In this way food security may be ensured across the globe by reducing food crisis. These observations indicate that Amur strain of common carp is suitable for replacing the common carp. Presently being used under composite culture by virtue of its better growth potential.

    Fish landing patterns and gonadal cyclicity of Notopterus notopterus (Pallas) in Baigul reservoir of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-05) Mondal, Anandamoy; Singh, I.J.
    The present study was undertaken to investigate fish landing and the reproductive cycle of the fish Notopterus notopterus in the Baigul reservoir located in the Uttarakhand state during the year 2006-07. Fish available in Baigul reservoir are grouped in to five categories i.e. A, B, C, D and E. Total fish landing was 2124.9 and 2044.61 quintal for the year 2006 and 2007 with the production of 70.93 kg/ha/yr and 68.27 kg/ha/yr respectively. Group C was dominant (38.68% in 2006 and 34.28% in 2007) followed by group D fishes (30.0% in 2006 and 30.44% in 2007). Landing of group A and B fishes has increased from 11.55 to 17.11% and from 6.64 to 8.35% respectively. In group A fishes highest contribution was by L. rohita followed by C. mirgala. Severe decline was recorded in landing of C. carpio from 22.33% in 2006 to 5.01% in 2007. Total fish catch was highest in June in both the years followed by in May and November to December in 2006 and November to January in 2007 indicating that some pattern in fish landing in Baigul reservoir was apparent which seems to be correlated with the fishing pattern and water depth or both. The range of water quality parameters noted for the year 2006 and 2007 from Baigul reservoir were pH (7.1- 7.8 and 7- 8.2); conductivity (120- 190 µ/cm and 115- 190 µ/cm); total dissolved solid (80- 137 mg/l and 80- 150 mg/ l); transparency (65- 180 cm and 61- 260 cm); dissolved oxygen (5.2- 7.6 ppm and 5.8- 7.5 ppm); CO2 (0- 6 ppm and 0- 8 ppm) and total alkalinity (78- 126 ppm and 85- 120.35 ppm) respectively. The r2 values were ranged from 0.57 to 0.89 for the year 2006 and 0.34 to 0.83 for the year 2007 and almost all the regressions were found significant (p< 0.001). Besides that the b values obtained for the species N. notopterus for the year 2006 was ranged between 0.058 to 3.075 and for 2007 between 0.950 to 2.794. The condition factor (CF) had shown positive significant correlation with gonadal development in male and female at different stages. Changes in CF might be correlated differently with the advancement of oocytes in ovary and spermatocytes in testis in same group or in fish of different size or age groups. Condition factor (CF) and somatic condition factor (SCF) being positively correlated in both the sexes of N. notopterus was indicative of increase of somatic component also along with rising gonadal weight. Pronounced negative correlation was observed between SCF and GSI in female N. notopterus, but was insignificant in their males. Condition factor and somatic condition factor being positively correlated in both the sexes N. notopterus was indicative was of increase of somatic component also along with rising gonadal weight. Pronounced negative correlation was observed between SCF and GSI in female N. notopterus but insignificant in males. Changes in GSI in both sexes of N. notopterus exhibited similar increasing pattern and seasonal cyclicity during both the years. Gondal development was more rapid during June, July & August to attain maturity for spawning. Lipid concentration in testis was much lower than in ovary of N. notopterus during spawning period and this could be due to fast ovarian growth and accumulation of yolk material in oocytes. The increased protein values in gonads during active reproductive phase compared to liver and muscle of N. notopterus are indicative of role of protein in gonadal development.

    Population genetic analyses of Labeo gonius (Hamilton,1822) in different reservoirs of Uttarakhand by using allozyme and RAPD markers
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-08) Tewari, Grishma; Singh, I.J.
    The present population genetic study was carried out to identify basic genetic structure of Labeo gonius from three different sized reservoirs of Uttarakhand viz., Dhaura, Baigul and Nanak Sagar reservoir by applying allozyme and random amplified polymorphic DNA (RAPD) markers. Allozyme analysis revealed total 19 loci out of which 11 were polymorphic (57.89%). RAPD-PCR produced total 11487 bands in overall populations by using 15 decamer operon series primers (OPA, OPB, OPC and OPY) with 32 individuals in each population. Out of total 11487 bands, 8344 bands were found to be polymorphic with a polymorphic band percentage of 72.63%. Other genetic diversity parameters were estimated by using software GENEPOP Ver.3.4 and POPGENE Ver. 3.1 for allozyme and RAPD analysis, respectively. Observed heterozygosity (Ho= 0.49-0.53), Nei’s genetic diversity (H= 0.39), Shannon’s information index (I= 0.57), total genetic diversity (Ht= 0.37) indicated most heterozygous structure in Nanak sagar population followed by Baigul and Dhaura reservoir. Values of Fst (0.106) and Gst (0.131) showed moderate genetic differentiation among the populations indicated little gene exchange with Nm value of 1.344. The allozyme and RAPD analysis in L. gonius concluded that these populations are not greatly differentiated from each other and presence of optimum level of genetic variation in Nanak sagar population in comparison to Dhaura and Baigul reservoir.
