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.

    The present study was designed to evaluate the physico-chemical factors and their effect on primary productivity in fish ponds. The experiment was conducted in three ponds viz. duckhouse pond and broodstock pond and nursery pond; having area of 0.1 ha, 0.2 ha and 0.05 ha, respectively which were situated at coordinates 28o58’N, 79o25’ E and at an altitude of 252 m above mean sea level, in Uttarakhand. Three sites in all the three experimental ponds viz. duckhouse pond (S1, S2 and S3), broodstock pond (S1', S2' and S3') and nursery pond (S1'', S2'' and S3'') were randomly selected and sampling was done fortnightly for the duration of six months i.e. from December-18 to May-19. In physical parameters water temperature, water transparency, electrical conductivity and total dissolved solids were found in the range of 15.9 to 32.5 oC, 28.0 to 54.8 cm, 201.0 to 587.0 μScm-1, and 138.5 to 424.5 mgL-1, respectively. In chemical parameters pH, total alkalinity, dissolved oxygen, free carbon dioxide, nitratenitrogen, phosphate-phosphorus, ammonia-nitrogen and silicate were recorded in the range of 7.6 to 8.4, 114.3 to 177.3 mgL-1, 4.9 to 8.5 mgL-1, 0 to 2 mgL-1, 0.32 to 0.51 mgL-1, 0.018 to 0.057 mgL-1, 0.09 to 0.35 mgL-1 and 2.56 to 5.09 mgL-1, respectively. The mean values of GPP, NPP and CR in experimental ponds were in the range of 2701.44 to 9506.88 mgCm-3d-1, 1287.36 to 4042.56 mgCm-3d-1 and 972.00 to 7874.88 mgCm-3d-1, respectively. The net production efficiency and chlorophyll a concentration in the study ponds was recorded in the range of 10.3 to 31.7% and 1.12 to 9.12 mgm-3, respectively. Phytoplankton composition of the experimental ponds consisted a total number of 24 different taxa belonging to 4 different classes namely Bacillariophyceae (12), Chlorophyceae (6), Cyanophyceae (4) and Euglenophyceae (2). The phytoplankton density ranged from 19350 to 69170 cellsL-1. Group wise distribution of phytoplankton density revealed that Bacillariophyceae was most dominant group in the experimental ponds. The maximum diversity was found in the month of May followed by April and December.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Chandra, Deepshikha; Mishra, Ashutosh
    The present study was designed to evaluate the effect of mycofiltration in fish culture. The experiment consists of seven treatments in triplicates as per water filtration rate viz T0(control treatment), T1 (8000 litre/day water filtration through mushroom spent bags), T1´(8000 litre/day water filtration through RAS), T2 (4000 litre/day water filtration through mushroom spent bags), T2´(4000 litre/day water filtration through RAS), T3 (2000 litre/day water filtration through mushroom spent bags) and T3´(2000 litre/day water filtration through RAS). Healthy and disease free fingerlings, of three fish species viz. Ctenopharyngodon idella, Cyprinus carpio haematopterus and Labeo rohita weighing with average weight 10±0.5 gm, 10±0.3 gm, 20±0.5 gm were stocked at the rate of 100 fingerlings/tank (25 fingerlings/m3) in the ratio of 35:35:30, respectively in the treatment tanks. The fingerlings were fed with 28% protein dry pelleted feed @ 3-5 % body weight. Evaluation of different physico-chemical parameters, heavy metals and microbial load was done in all the treatment tanks. Weekly analysis of water quality parameters viz temperature, conductivity, total dissolved solids, dissolved oxygen, free carbon dioxide, pH, total alkalinity, ammonia, nitrate and phosphate was done to observe their variation in different treatment groups.During the experiment different range of physico-chemical parameters was obtained in all the experimental tanks viz Temperature (15.2-28.7°C), conductivity (312-594.75μS cm-1), total dissolved solids (156-391.75 mgL-1 ), dissolved oxygen (3.5-7.17 mgL-1), free carbon dioxide (1-5.4 mgL-1), pH (6.7-8.2), total alkalinity (66.5-259 mgL-1), ammonia (0.012-0.24 mgL-1), nitrate (0.1-5.2 mgL-1) and phosphate (0.01-0.62 mgL-1). The net weight gained during the investigation period by experimental fishes Labeo rohita, Ctenopharyngodon idella, Cyprinus carpio haematopterus, in the treatment groups was 116.59-133.13g, 103.42-123.28g, 51.37-59.36g respectively. Evaluation of heavy metals and microbial load done during the study period resulted in decrease in the concentration of heavy metals and microbial load at the end of the experiment. The above research revealed that mycofiltration technique is useful for the growth of fishes in the polluted water bodies with heavy metals and microbial load. This technique makes the suitable condition of the hydrographical parameters and does not cause stress in the environment for the fishes. It is an integrated technique with mushroom cum fish culture and is easy to be handled and very cost effective.

    Effect of herbal based micronutrients premix supplemented diet on growth and survival of post larvae of Cyprinus carpio haematopterus (Amur carp)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Tiwari, Abhishek; Khati, Akansha
    A feeding trial was conducted to evaluate the effect of herbal based micronutrients premix on growth and survival of post larvae of Cyprinus carpio haematopterus (Amur Carp) and to assess the impact of micronutrients premix on physiochemical properties of water. The experiment consisted of four treatments (T1 to T4) in triplicate. Fifty post larvae of Cyprinus carpio haematopterus of uniform size (1.75 ± 0.01cm length, 0.175g±0.005 weight) were stocked in 12 Aquariums (1.2 0.3 0.3). Three isonitrogenous diets containing 28 ± 0.5 crude protein were prepared using deoiled rice polish (50%) and deoiled groundnut cake (50%). The post larvae of treatment T1 were fed with diet D1 (no supplementation). The post larvae in treatment T2 and T3 were fed with diet D2 (1% premix supplemented) and D3 (2% premix supplemented) respectively. Post larvae of treatment T4 were fed with diet D1 and D3 on alternative days (i.e. 2% premix supplemented on alternative days). The larvae were fed @ 16% body weight divided into 3 equal portions. The water quality parameters were observed daily. The survival percentage of post larvae in T1, T2, T3 and T4 were recorded as 80, 94, 98 and 91.32% respectively. Rearing of post larvae with diet D3 (2% premix) achieved significantly enhanced SGR (1.45), FCR (2.64) and FCE (0.38). The above research revealed that herbal based micronutrients premix has very good growth promoting potential in raising post larvae of carp and its supplementation has no adverse impact on the water quality parameters as well as on fish feeding behavior. Based on the study it is recommended that herbal based micronutrients premix be incorporated @2% daily in fish feed for enhancing growth and survival of post larvae of carp fishes up to fry stage.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Asma Amin; Chauhan, R.S.
    The present study was carried from April to August 2018 to evaluate the effect of Withania somnifera (Ashwagadha) on the female brooders of Indian major carps (Labeo rohita). A total of 120 Labeo rohita female brooder fishes with average weight 830.455± 0.18g were dispersed randomly into four treatment groups T0 (control), T1, T2 and T3 @ 30 females/treatment. Experimental diets were prepared by mixing rice bran, deoiled mustard oil cake, deoiled soybean cake, maize and vitamin mineral mixture. The ashwagandha was incorporated into diet D1 @ 1.0%, D2 @ 1.5%, D3 @ 2.0%. In control diet D0, ashwagandha was not incorporated. T1 group fishes were fed with D1 diet, T2 with D2, T3 with D3 @ 3% body weight per day for 120 days. The water quality parameters were in optimum conditions and ashwagandha showed no detrimental effect on quality of the. Brooders fed with diet D3 achieved better GSI (22.41%), fecundity/gm ovary weight (1753.33) and ova diameter (0.77mm) as compared to other treatments. T3 group of fishes showed higher value of TLC (15.85×103/μl), TEC (1.67×106/μl), Hb concentration (7.84 g%), PCV (23.03%), MCV (137.64μm3), MCH (46.90pg), and MCHC (34.70g/dl), Total serum proteins (3.01 g/dl), Albumin(1.073 g/dl) and Globulin (2.04 g/dl) as compared to control and other treatments, thus showing better haematological and serological profile in treated fishes over control. HSI showed negative inverse relationship with the GSI and was recorded highest in all the control groups. Thus the obtained results indicated that the root powder of ashwagandha has prime importance in improving reproductive performance and immunostimulatory potential in Labeo rohita.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Rathod, Vishalbhai Jodhabhai; Rajesh
    The present study was carried out to elucidate the effect of different thermal regimes on growth and immuno-biochemical responses of golden mahseer (Tor putitora) fingerlings. Initially, around 200 golden mahseer fingerlings were collected and acclimatized at 20 °C for 10 days. Then 144 healthy fingerlings (9.0 ± 0.23 cm length and 8.36 ± 0.45 g weight) were randomly distributed into four experimental groups (Ambient temperature; ABT-control, ABT+3 C̊ , ABT+ 6 C̊ , ABT+ 9 ̊C) in triplicate rectangular FRP tanks. Fishes were fed with formulated pelleted feed twice daily (10.00 am and 5.00 pm) @ 2 % body weight. Growth and water quality parameters (temperature, pH, DO, free CO2, alkalinity) were analysed during the study period. At the end of the experiment, immunological parameters (i.e. glucose, haemoglobin and haemetocrit, lysozyme, myeloperoxidase) and stress biomarkers (i.e. growth hormone, lipid peroxidation, antioxidative potential, superoxide dismutase, catalase and glutathione s-transferase) were analysed. All the water quality parameters were suitable for golden mahseer fingerlings. Result showed significantly higher growth, specific growth rate and growth hormone levels observed at ABT+ 6 ̊C group compared to other group. Lower FCR was obtained at temperature 19.52 ± 0.71 °C. Hepato-somatic index was found maximum at ABT while viscera-somatic index was maximum in ABT+ 3 C̊ group. Result on length-weight relationship was shown allometric growth in golden mahseer fingerlings. Haemoglobin and haemetocrit values significantly decreased with increase in temperature. Myeloperoxidase activity was found higher upto temperature ABT+ 3 C̊ and its activity decreased in ABT+ 6 C̊ and ABT+ 9 C̊ groups. Highest lysozyme activity and TBARS levels were evident in ABT+3 C̊ group. Anti-oxidant potential was found highest at ABT group and decreased gradually with increase in temperature. The response of anti-oxidative enzymes was tissue specific and significantly different at different thermal regimes. Present study reveals different phenotypic and immuno-biochemical modulations of golden mahseer fingerlings in response to different temperature regimes which can be used for its better management and propagation.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Pathak, Yogesh; Sharma, A.P.
    The present study was done in an artificially aerated Lake Naukuchiatal to examine phytoplankton community structure and primary productivity along with various pyshico-chemical parameters of the lake. Three sampling sites named as S1 (Pump house), S2 (Midpoint) and S3 (Chanauti) were selected for the study. S1 was present in littoral zone whereas S2 and S3were located in the limnetic part of the lake. Samples were collected fortnightly from surface, 8m, 16m and 32m depths to evaluate the water quality and phytoplankton community for a period of 8 months from October 2017 to May 2018. A significant difference in some parameters of water quality viz. temperature, DO (S3), nitrate and phosphate vertically were recorded. Whereas differences in TDS, conductivity, DO (S2), CO2 and alkalinity were not significant and almost uniform limnological conditions were observed throughout the water column of the lake as consequence of aeration. A total of 28 species of phytoplankton were reported belonging to 3 groups viz, Bacillariophyceae (11 species), chlorophyceae (14 species) and cyanophyceae (3 species). Members of Bacillariophyceae and Chlorophyceae were found to be dominant during the study period. Phytoplankton population was recorded upto the bottom waters in contrast to the non-aerated water bodies as mixing of entire water column allows phytoplankton to be distributed across the whole water column. Gross primary productivity of the lake showedminimum value in February (5.21 ±0.52 mgC/m3/hr) and maximum in May (12.04 ±0.98 mgC/m3/hr)and the lake reflected mesotrophic conditions during the entire study period. Despite organic pollution, dissolved oxygen was available at each depth. The details of the findings of the investigation is presented in different chapters of the thesis

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Pandey, Tanuja; Rajesh
    The present study was conducted to observe the effect of stocking density on growth and survival of Pangus (Pangasianodon hypophthalmus) in circular FRP tanks for a period of 3 months having capacity of 4.9 m3. A total of 2160 fishes were randomly divided into four different stocking density 30, 40, 50, 60 fish/m3 and designated as treatment T1, T2, T3 and T4 respectively. Each treatment has three replicates and is maintained water volume 4000 litres in all experimental tanks. All the fishes were stocked in each tank having average length and weight 10.07􀁲0.009 cm and 22.07􀁲0.009g respectively. After one week of acclimatization period, the experimental fish were fed with a diet containing 30% protein. The feed was given twice a day (morning and evening) @ 10% of the total body weight for the first month and then reduced to 5% of the total body weight for the remaining two months of the rearing period. Growth parameters (feed conversion ratio, weight gain, specific growth rate, survival rate, condition factor) and water quality parameters (temperature, pH, dissolved oxygen, free carbon dioxide, total alkalinity, total dissolved solids) were analysed during the study period. The result of water parameters showed no significant difference (P>0.05). The study showed that fish in treatment T1 stocked at the rate of 30 fish/m3 indicate the best individual weight gain followed by T2, T3 and T4 respectively. The specific growth rate (SGR) ranged between 0.40 to 0.49 % per day, the food conversion ratio (FCR) values ranged between 1.78 to 1.84 with treatment T1 resulting the lowest FCR. The growth performance and survival was influenced by stocking density. A decreasing trend are found in final weight of fishes along with the increasing stocking density. The present study revealed that best individual growth and survival of Pangasianodon hypophthalmus were obtained at a stocking density of 30 fish/m3 but the highest total biomass production was found at a stocking density of 60 fish/m3 in circular FRP tanks.
