Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2015-07) Majhi, Uday Singh; Upadhyay, A.K.ThesisItem Open Access Haematological and biochemical changes in Cirrhinus mrigala (Nain) in relation to season, sex and reproductive status(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Ratnakar, Sneha; Singh, I.J.Some haematological and biochemical parameters of the fish Nain, Cirrhinus mrigala, collected from Instructional Fish Farm, College of Fisheries, G. B. Pant University of Agriculture and Technology, Pantnagar India were studied from October 2015 to June 2016. Variations in haematological parameters such as haemoglobin, Total Erythrocyte Count, Total Leucocytes Count, haematocrit, Mean Corpuscular Volume (MCV) and Mean Corpuscular Haemoglobin Concentration (MCHC), and Biochemical parameters total protein, albumin and globulin of this fish were compared in relation to season, sex and reproductive status. Observations showed that there was significant difference between these parameters and the season. The results indicated that the blood parameter levels of most of the parameters were significantly different in both the sexes in summer (pre-spawning season) than other seasons except Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Volume in males (MCV) value (P <0.05). The number of total leukocyte was found to be higher in female fish especially in pre spawning season (summer) but the levels of Total Erythrocyte Count, haemoglobin, haematocrit MCV and MCH values were high in male fish during over all study period. However, there was no difference in MCH and MCHC values between the sexes and seasons throughout the study period. This might be due to the reason that seasons of sampling and physiological cycles were changing during these months. No significant difference was found in haematological parameters in both male and female fishes (P˃0.05). In conclusion, the present study showed that the haematological and biochemical parameters in blood of Cirrhinus mrigala were correlated with the seasons and reproductive status but despite there being contrary differences in the values of these parameters studied in both the sexes of this but the differences remained insignificant.ThesisItem Open Access Studies on selected heavy metals in fish, sediments and water of Kosi and Sharda rivers of Uttarakhand(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-07) Manish Kumar; Saxena, AmitaThesisItem Open Access Study of biodiversity and microbial load in rivers Kosi and Sharda(G.B.

Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-05) Joshi, Deepak; Ram, R.N.The present study was conducted to investigate the level of polymorphism and genetic diversity in natural population of Labeo rohita collected from selected zones of River Ganga (from Haridwar and Kanpur region) and also in the cultured population (from Instructional Fish Farm of College of Fisheries, Pantnagar) using microsatellite DNA markers. 5 primers out of 10 produced amplicons and were selected for primary screening and further genetic analysis of the population. On the basis of the values of Average Nei’s Genetic Diversity, observed and expected heterozygosity, fixation index, Shannon’s information index and cluster analysis obtained by microsatellite marker technique, the present study is the indicative of the fact that the stock of L. rohita of Haridwar region of River Ganga is more genetically diverse and genetically differentiated as compared to the stock of Kanpur region as these sites are distantly located and having negligible chance of exchange of gene pool with each other which is responsible for weak sub-structuring of stocks. Genetic variation observed between the two riverine sites may also be caused due to high level of anthropogenic activities in Kanpur region thereby causing blockage of fish movement as well destruction of breeding grounds thus hampering the proper mating within the population and also reducing effective population size. The present finding also indicates that L rohita samples collected from riverine system showed very high level of genetic diversity and negligible inbreeding in comparison to the population present in captivity. The lesser value of heterozygosity and increased inbreeding in population of L rohita from culture as compared to wild might be due increase in incidents of repeated breeding in successive generations owing to lack of regular germplasm exchange of appropriate genetic diversity. Genetic diversity analysis also revealed substantial changes in genetic variation and significant genetic distance between the wild and farm-produced populations of L. rohita.ThesisItem Open Access Evaluation of biological efficacy of natural antioxidants (Vitamin C and E) in common carp(G.B.

Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2016-08) Ruwali, Khimesh; Tewari, HemaBhimtal lake is a shoe shaped lake with an altitude of about 1370m above sea level. It is one of the famous tourist places of Central Himalaya. Lake has an island near the centre which has been converted into beautiful aquarium by lake authorities. Lake Sattal is an interconnected group of seven fresh water lakes situated at Lower Himalaya near Bhimtal, a town of the Nainital district in Uttarakhand. Lake is located at an elevation of 4000 feet approximately situated in Nainital district. Physico-chemical parameters and heavy metal concentration of Lake Bhimtal and Sattal was studied for a period of five months i.e. January 2016 to May 2016 to assess the water quality and level of heavy metal pollution in the water. Two sites from each lake were selected for sampling. The two sampling sites at Lake Sattal were S1 and S2 and from Bhimtal B1 and B2 were considered as sampling site. Site S2 is 150 meters horizontally far from site S1 and in Bhimtal site B1 is near the boat area and site B2 is also 150 meters away from site B1. Average values of physical parameters like Temperature, Electrical Conductivity and Total Dissolved Solids were 15.7˚C, 239.3 µS/cm and 87.7 mg/L, respectively in Lake Bhimtal whereas 15.6˚C, 204.9 µs/cm and 122.6 mg/L, respectively was found in Lake Sattal during study period. Average value of chemical parameters, pH, Dissolved Oxygen, Free CO2 and Alkalinity, was 7.7, 7.9 mg/L, 0.2 mg/L and 90.2mg/L, respectively in Lake Bhimtal and 7.8, 7 mg/L, 0.3 mg/L and 92.8 mg/L, respectively in Lake Sattal during study period. Average concentration of Lead (Pb), Copper (Cu), Zinc (Zn), Cadmium (Cd) and Iron (Fe) was 0.19 mg/L, 0.0078 mg/L, 0.05 mg/L, 0.0044 mg/L and 1.20 mg/L, respectively in lake Bhimtal whereas 0.01 mg/L, 0.0127 mg/L, 0.049 mg/L, 0.0035 mg/L and 0.065 mg/L ,respectively in lake Sattal. Highest average concentration of Lead, Zinc, Cadmium and Iron was always found in site B2 and Copper in site B1 in Lake Bhimtal whereas in lake Sattal highest value of Copper, Zinc and Cadmium were found in site S1 and Iron and Lead in site S2. Variation in concentration of heavy metals like Lead, Copper, Zinc and Cadmium was not in wide range but the average value of Iron in Lake Bhimtal was 1.2 mg/L and in Sattal was 0.065 mg/L. By the investigation it is concluded that Heavy metal contamination in lake Bhimtal is more than in lake Sattal. Presenlty, lake water is not lethal for aquatic organisms but if the concentration of heavy metals goes beyond the range of permissible limit then it can become harmful for both aquatic organisms and human beings.
