Publisher: 2016Dissertation note: Present study was planned to compare egg quality, hematology and reproductive traits in ring necked and green pheasants in captivity. Day-old chicks of both the pheasant species Phasianuscolchicusand P.versicolorwere tagged individually and maintained initially in a room for a period of 4 weeks. The chicks were then transferred to cages provided with separate feeding and drinking facilities to the individual bird. The birds were kept until the 16 weeks of life. The sex of the chicks was predicted at early stages by observing feathers and plumage and was confirmed later at adult ages.
Eggs (n = 100) of both the pheasant species i.e. Phasianuscolchicusand P.versicolorwere collected. Each egg was weighed and its length and breadth was taken. These eggs were divided into three weight groups and were classified as light, medium and heavy category. The length and breadth of each collected egg was taken and surface area, egg volume and shape index were calculated.The egg quality test was performed on freshly collected eggs in the egg quality testing laboratory periodically. The eggs were weighed carefully on electronic digital balance. The albumen and yolk height and width, yolk index, albumen and yolk pH and Haugh unit score were recorded.
During present study, chick weight in ring necked pheasants Phasianuscolchicusand green pheasant P. versicolorfrom day old chick to 6-month stage varied significantly. The average body weight in day old chick weight ranged from20.6±1.35g to 24.50±1.29g.Increase in chick weight in male ring necked pheasants was 24.50±1.29g to 1235.25±101.81g. Similarly increase in female ring necked pheasant was 22.47±1.79gto 1004.75±52.94g.The chick average weight was almost double during 2nd week. Body length was maximum in male green pheasant 5.00±0.81cm during 1st week. However significant (p<0.05) increase in body weight was observed during 1st to 4thweek.Higher increase in average body weight was observed during 6thweek. Significantly (p<0.05) increase in wing length and wing span was also recorded during 6th week. During 7thweek, non-significant differences in body weight were observed between male and female P. colchicus.Overall, minimum increase in chick weight was observed during 21st,22nd and 23rd week and maximum during 6th,7th and 8th week of chick age. The chick weight at hatching in light, medium and heavy egg groups were determined as 19.5g, 21.8g and 22.6g, respectively.
Lowest increase in chick body weight in green pheasants ranged from 20.6±1.35g during 1st week to 837.00±49.45g during 24thweek of its growth. During present study it was determined that hatched chick weight increases with increase in egg weight. After completion of the incubation, the infertile egg percentage was 48% in ring necked pheasant and 42% in green pheasant. Increase in wing length varied significantly in male and female and between both species from day old chick to 6-month stage. The lowest increase in chick’s wing length ranged from 5.37±1.10cm to 33.75±1.70cm in female P. versicolor. Overall minimum increase in wing length was observed during 12thweek and maximum during 2nd,3rd and 6th week of chick age.
During present study, significant differences in various hematological parameters were recorded during different ages of pheasants. RBCs values in P.cholchicusincreased with age, reached a maximum point then decreased. While in P. versicolorthe values decreasedat juvenile stage and then increased to young ages and decreased. However, maximum 4.04±0.6 values for RBCs were recorded in P. versicolorduring 3rd month. In young age,significant (p<0.05) differences in blood biochemical profile of both the pheasant species were observed.

Publisher: 2016Dissertation note:
Metallic and non-metallic pollutants originating from different industries are not treated before their final discharge into the environment. Consequently, environment is being degraded very rapidly and posing serious threats to all forms of life. For remediation of the said pollutants, a number of physico-chemical treatment methods have been practiced but couldn’t found suitable due to environmentally non-compatible natures and generation of secondary pollutants.
The present study was, therefore, designed to treat artificially prepared sulfate-rich wastewater jointly with the help of cellulolytic and sulfate-reducing bacterial species while using a variety of agro-industrial wastes as cost-effective growth substrates. In order to achieve the goal, the two bacterial species were mixed in different proportions to achieve significant results of sulfate reduction.
Statistical analysis revealed that rice straw appeared as the most efficient carbon source among all the agricultural wastes because it reduced about 96% of the total added sulfate in a 60-day trial of anaerobic incubation. And among all the industrial wastes, animal manure appearedasthe most efficient carbon source, it could reduce 93% of sulfate. Mixture of industrial and agricultural waste reduced about 90% of the sulfate. Findings of this project will be helpful in developing an economical and environmental friendly bio-remedial technique for the treatment of metallic and non-metallic wastes simultaneously which ultimately convert the industrial wastewaters into harmless and suitable discharge to aquatic environment.

Publisher: 2016Dissertation note: In Asia Carp culture is dominated which is mostly extensive and semi-intensive. Now a days aquatic plants used in animal feed became very popular. Aquatic plants have been used to enhance the growth, reduce stress, induce appetite and play a major role as Immunostimulants that have antimicrobial effects in fin fish and shrimp. However, exact percentage contribution needs to be determined to obtain its benefits as over dose can have harmful effects. These plants are mechanically removed at a high costs and dumped. So, the use of unusual feed resources is a way of significant reduction in the cost of feed.
Addition of Aquatic plants upgrade growth, enzyme level, body composition and immunity of Labeorohita (rohu) fingerlings.This study will produce useful information for aqua feed and fish industry concerning possible utilization source of aquatic plants for carp. It will also be helpful to save the increasing cost of aqua feed industry because of cheaper source of energy inproving health of fish thus enhance production.
To compare the growth performance and meat quality of Labeorohitaunder different treatments
Experiment was designed in glass aquariums and with two replicates in each treatment. The effect of inclusion of aquatic plants in the feed of Labeorohitawas also observed on histology under different treatments in aquariums. Before stocking all aquariums was disinfected with KMnO4. Each aquarium was stocked with 15 Labeorohitafingerlings and their morphometric parameters i.e,body weight and total length was recorded at the time of stocking. The physico-chemical parameters (DO, pH and Temperature) was monitored on daily basis from each treatments. For proximate and histological studies organs of fish was collected at the end of experimental. The feed was formulated for treatment T1, T2, and T3 having 35%, 30% and 25% of plant (Vallisneriaspiralis). The fish samples were captured randomly from each of the treated aquarium and their morpho-metric characteristics viz. total body weight and total length were recorded on weekly basis. And after obtaining the data the fish were released back into their respective aquarium. At the final harvest, the proximate composition of fish meat sample was studied.
The findings of the present experiment are summarized as follow.
1-The average body weight of Labeorohitaremained as 91.2, 71.3, 62.2 and 58.2g under the treatments T1, T2, T3 and T4 respectively.Fish attained the maximum average body weight in T1 which was treated with 35% plant.Among the different treatment, maximum body increment in body weight was recorded in T1 as 91.2(g) whereas minimum body weight was recorded in T4 as 58.2 (g)..
2-Labeorohitashowed the minimum value of specific growth rate as 0.422 and 0.463 in T3 and T4. Maximum value of 0.789% of specific growth rate was noted in T1.
3-Among different treatments the maximum condition factor was observed as 2.717% in T1 while minimum was gained as 1.918% in T4.
4-Among different treatmentsLabeorohita showed the highest growth rate with the highest crude protein contents 18.70% under the treatment T1. while17.85%, 17,60% and 17.35% in T2, T3 and T4.
5-The maximum moisture content was observed as 75.22% in T1 and minimum moisture content was observed as 73.20% in T4
6-The maximum value of total fats was observes as 1.29% in T4 and minimum value was observed as 1.13% in T1 treatment
7- Among the abiotic factor water temperature played major role towards fish growth as higher increase in body weight was observed for all the treatments during July and august while minimum increase in body weight was observed in September and October which perhaps due to low water temperature.Maximum water temperature was observed as 24.6 °C in T1 and T3 treatments. While minimum was recorded as 21.3 °C.
8-The physico-chemical characteristics of water remained within the favourable limits for fish culture.and shows non-significant under all treatments.
