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.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-12) Sable, Monica Rajkumar; Trakroo, M. Das
    Assessment of Phytoplankton and Zooplankton of four lakes namely Nainital, Bhimtal, Naukuchiatal and Sattal was made from November 2020 to April 2021 in the present investigation to evaluate plankton diversity of the lakes. Three sites viz., S1, S2 and S3 were selected in each lakes on the basis of human interference and fortnightly sampling was done. The important physico-chemical parameters such as temperature, transparency, TDS, electrical conductivity, pH, DO, alkalinity, hardness, nitrate and phosphate of the lakes varied from each other. The phytoplankton mainly consists of Bacillariophyceae, Chlorophyceae, Cynophyceae, Euglenophyceae and Dinophyceae whereas zooplankton mainly consists of Rotifera, Copepoda, Cladocera and Ostracoda. A total of 46 species of phytoplankton were recorded in lake Nainital, Bhimtal, Naukuchiatal which comprises of members of Bacillariophyceae (21 species), Chlorophyceae (17 species), Cyanophyceae (5 species) Euglenophyceae (2 species) and Dinophyceae (1 species). In sattal lake, a total of 44 species of phytoplankton were recorded which comprises of members of Bacillariophyceae (21 species), Chlorophyceae (17 species), Cyanophyceae (5 species) and Dinophyceae (1 species). Euglenophyceae was not found in lake Sattal during the study period. 25 genera of zooplankton were recorded in the selected lakes, out of which 10 genera belong to Rotifera, 7 genera to Copepoda, 6 genera to Cladocera and 2 genera to Ostracoda. The average density of phytoplankton and zooplankton at Nainital lake was 60750±10471 cells L-1 and 4215±505 ind. L-1 respectively. Phytoplankton and zooplankton population 64583±8712 cells L-1 and 4439±623 ind. L-1 respectively at Bhimtal lake. The average density of phytoplankton and zooplankton at Naukuchiatal lake was 68722±5688 cells L-1 and 4404±137 ind. L-1 respectively, in Sattal lake it was 65833±9976 cells L-1 and 4529±308 ind. L-1 respectively. The study concludes that Naukuchiatal lake is more diverse than the other lakes in terms of planktonic diversity due to less pollution and better hydrological regime and constant aeration. Also, the limnological parameters of all the selected lakes revealed that the environmental conditions are good from fisheries point of view.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-12) Bisht, Diksha; Tiwari, Hema
    The present research was done to study nutrient dynamics of water and growth parameters of Labeo rohita grown in aquaponic system with selected medicinal plants. The small plants, Tulsi (Ocimum tenuiflorum), Aloe vera and Mint (Mentha spicata) and fingerlings of Rohu (Labeo rohita) was collected from the hatchery of College of Fisheries, Pantnagar. Small plants of was grown in polyhouse in a FRP rectangular size trough of size of 176 × 44 × 17 cm. The trough was filled with stone gravels of size 8 – 20 mm. The average length and weight of rohu fingerlings were 6±1cm and 4±0.5g. The present study was carried out in rectangular cement tank filled with 8000 litre water and stocked with 400 numbers of fingerlings in each tank designated as T1 (Tulsi), T2 (Mint) and T3 (Aloe vera) respectively. A control without any plant but 400 rohu fingerlings was run simultaneously for comparison. Experiment was run with three replications for a duration of 6 months from October 2019 to march 2020. All water quality parameters were analysed weekly. Monthly sampling of length and weight of fishes was done. Initial and final biomassLwere taken at starting and ending point of an experiment. The fingerlings of different groups were fed with 1% respective medicinal plant extract incorporated floating commercial 28% protein based pelleted feed prepared by using different ingredients viz. groundnut oil cake, rice bran, maize, fish meal etc.. Every day 2.5% i.e 200L of water from fish tank removed and given to the plants in aquaponic unit. Approximately half an hour of time will be taken by each trough. The result of the present study showed that aquaponic system having integration with medicinal plants are capable of utilizing waste of one system for another biological system. Aquaponics with Aloe vera showed better growth of Rohu along with better productivity of Aloe vera as compared to other treatment tanks. Aquaponics with Tulsi showed better BCR as compared to other treatment tanks.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Saikia, Antareepa; Saxena, Amita
    The incorporation of geospatial technology with multi criteria decision-making method using Analytical Hierarchy Process (AHP) in this study has made it possible for the identification of the potential sites in the selected lakes for the development of coldwater fisheries in the district of Tawang, Arunachal Pradesh. The highly suitable areas of 6.24 ha (33.50 %), 1.14 ha (33.26 %), 2.19 ha (26.89 %), 0.27 ha (29.99 %) and 1.58 ha (16.90 %); moderately suitable areas of 1.45 ha (7.76 %), 0.63 ha (18.53 %), 5.61 ha (68.95 %), 0.40 ha (44.02 %) and 2.18 ha (23.27 %) were recorded for Sela, Nagula, Panga Teng Tso, an un-named lake and Sangestar, respectively. The physico-chemical parameters ,i.e., temperature ( 4.9±0.05°C to 8.2±0.05°C), electrical conductivity (3.1±0.00 μS/cm to 52.35±2.35 μS/cm), total dissolved solids (2.0±0.0 mg/L to 33.5±1.5 mg/L), dissolved oxygen (6.77±0.010 mg/L to 8.33±0.100 mg/L), carbon dioxide (2.00±0.000 mg/L to 2.50±0.09 mg/L), pH (6.7±0.15 to 7.9±0.05), phosphate (0.010±0.000 mg/L to 0.270±0.010 mg/L), nitrite (0.003±0.000 mg/L to 0.0085±0.0005 mg/L), iron (0.07±0.020 mg/L to 0.265±0.015 mg/L) and ammonium (0.010±0.000 mg/L to 0.020±0.001mg/L) were found to be quite conducive for coldwater fisheries development in the selected lake resources. The biological parameters, i.e., phytoplankton and zooplankton numbers were comparatively greater in the highly and moderately suitable areas than that in the unsuitable areas of the lakes. However, 10.94 ha (58.73 %), 1.65 ha (48.21 %), 0.34 ha (4.15 %), 0.24 ha (25.99 %) and 5.60 ha (59.83 %) were accounted as the unsuitable areas in Sela, Nagula, Panga Teng Tso, un-named lake and Sangestar lakes, respectively which are, therefore, deemed inapt for any fisheries development. Overall, it was found that coldwater and sports fisheries development can be taken up in the selected lake resources of the district.

    Assessment of Azolla efficacy on growth and survival of grass carp (Ctenopharyngodon idella)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-12) Arya, Diksha; Khati, Akansha
    A feeding trial of 90 days was conducted to examine the efficacy of Azolla on growth and survival of grass carp (Ctenopharyngodon idella) fingerling. Azolla microphylla was selected for the experimentation due to the suitability of this species to grow in the cold climate. Cultivation of azolla, cooking treatment to reduce the anti nutritional elements from fresh azolla, proximate composition of azolla, preparation and proximate composition of test diets, data observation on length and weight, L-W relationship, condition factor, FCR, survival rate, growth assessment by RNA:DNA ratio and recording of physio- chemical parameters of pond water were the major work elements of the study. Azolla can be incorporated upto 40%, which is favourable for better growth and also reduce the high priced protein ingredients in the feeding of grass carp fingerlings. Cooked azolla at 1000C for 15min is more useful for growth of fingerlings rather than use of fresh azolla. Azolla seems to be good replacer of protein from expensive sources such as mustard oil cake, soybean cake depending on feeding habits of the species. Also, the dietary Azolla supplementation shows to have a positive effect on growth and survival of fish without deteriorating the water quality. Use of cooked azolla rather than fresh azolla would be helpful for the aquaculture of grass carp in mid hill conditions. Findings of the study are directly applicable for the coldwater aquaculture practice.
