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), 2019-08) Rathor, Prerna; Sharma, A.P.
    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.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-06) Laxmi; Upadhyay, A.K.
    Comparative study was conducted to find out the efficacy of model carp hatchery with best performance of Chinese circular hatchery for seed production of carp fish. Experiment was conducted at College of Fisheries, Pantnagar with comparative study of different Physico-chemical parameters and breeding parameters in both the hatchery systems, during the same breeding season and with same brood stock. Functioning of model carp hatchery has also being optimized for water flow rate, stocking density and hatching period, which has been found as 8 l/min, 80 thousand and 24 hrs respectively. The suitable range of water temperature as 250C to 270C and dissolved oxygen content as 9.0-11.5 ppm with almost constant pH around 7 has been recorded for best recovery. Low level of free Co2 and increasing trend of alkalinity, after hatching of eggs with highest value of alkalinity as 72 ppm was found in model carp hatchery. Increasing trend of nitrate and phosphate was found after the hatching of eggs with maximum values as 16.123 μg/l and 0.205 μg/l, respectively. Indian major carps experienced better for all breeding parameters and finally spawn recovery as compare to Chinese carps with both the systems. Comparatively model carp hatchery was found to exist the most optimal levels of different Physico-chemical parameters with slightly higher recovery than the Chinese circular hatchery, indicating the suitability of the model carp hatchery for rural and resource poor aqua farmers.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Roy, Samar; Upadhyay, A.K.
    The present study was conducted to asses the growth performance of golden mahseer fry under different temperature regime and with different concentrated protein diet. An attempt has also been made to standardize and asses the extreme lethal temperature for survival of mahseer fry. In order to find the extreme lethal temperature limit an experiment was conducted in laboratory condition in glass aquarium maintaining temperature 9, 10, 11, 23, 30, 34, 36 and 370C for 96 hours and it was found that the temperature 90C and below or 370C and above are highly lethal for survival of fry. The assessment of growth performance of mahseer fry was conducted under different rearing temperature maintained at 20.82 ± 2.250C, 25.74 ± 2.790C, 30.86 ± 2.440C and room temperature (11.20 ± 2.840C) administrating the formulated diet of 38.79% protein in indoor condition. The result on basis of weight gain, survivality and SGR revealed that the suitable temperature for mahseer fry growth lies between 20-300C with 250C as optimum. The present study also encompasses the comparative performances of endangered cyprinid, Tor putitora at two geographical locations viz. Bhimtal and Pantnagar having different inhabitant temperature by maintaining 20.9%, 30.86% and 38.74% crude protein levels in diet. The finding of growth in terms of length gain, weight gain, SGR and survivality indicated the excellent performance at 38.74% of crude protein level in the diet. The whole body carcass composition from the experimental fry exhibited increasing levels of protein, lipid and decreasing levels of moisture fed with increasing dietary protein levels. In an attempt to correlate the growth performance of mahseer fry in varying temperature and dietary protein at molecular level, certain key enzymes viz. amylase, protease, GOT, LDH along with total DNA content were evaluated. The amylase and protease activity showed a significantly (P ≤ 0.05) positive relation with increasing temperature from 11 to 300C and total DNA showed positive relation up to 250C. Protease activity and total DNA content also showed positive relation with the increasing dietary protein levels, whereas amylase activity with increasing dietary carbohydrate levels. However GOT and LDH did not exhibited any particular correlation under the varying temperature and different protein regime in the diet.

    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.
