ThesisItem Open Access PHYSIOLOGICAL DISTURBANCES IN COMMON CARP (Cyprinus carpio) AS AN INDICATOR OF POLLUTION STRESS(KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2011-09) MUTTAPPA KHAVI; H.R.V.REDDY; A.T.TAMCHANDAR NAIK; K.S.RAMESH; MRIDULA RAJESHThe use of insecticides is being increasing in the recent years to control the pest in which only 1% of the pesticide applied hits the target pest while, the remaining 99% of the pesticide drifts into the environment contaminating soil, water and biota. This poses a constant threat to the non-target organisms especially to fishes, because pesticides are known to alter their behavioral pattern, growth, and physiology. One of the early symptoms of acute pesticide poisoning is failure of respiratory metabolism, reduction in the food consumption, alteration in absorption efficiency, scope for growth and oxygen: nitrogen ratios of fishes. A static renewal bioassay was conducted to determine the acute toxicity (LC50) of commercial grade Organophosphate insecticide, Quinalphos (25% emulsified concentration) to common carp (Cyprinus carpio). The acute toxicity of Quinalphos to carp fingerlings exposed for 96 h was found to be 2.75ppm. For sublethal toxicity study, the fishes were exposed to two sublethal concentrations (1/10th of LC50 i.e 0.275ppm and 1/5th of LC50 i.e 0.55ppm) with lethal concentration (2.75ppm) for up to 48 hours. The carps were found to be under stress but mortality was insignificant in both sublethal and lethal concentrations. Considerable variation in respiratory rate was observed in both sublethal and lethal concentrations. 84 The effects of this pesticide on the physiological condition were remarkable. Food consumption rate, absorption efficiency, scope for growth and Oxygen: Nitrogen ratio of the fishes was affected when it was exposed to increasing concentrations of Quinalphos. The observed alteration in physiological condition may be a consequence of impaired oxidative metabolism and elevated physiological stress by the fish against quinalphos stress.ThesisItem Open Access EVALUATION OF COMBINED EFFECTS OF YEAST CELL WALL EXTRACT AND SPIRULINA BASED FEED ON THE GROWTH AND HEALTH OF CATLA CATLA(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2012) VARUNA BAGLODL, B.F.ScThe global production of fish, crustaceans and molluscs has continued to increase and reached 144.6 million tonnes in 2008ThesisItem Open Access VIABILITY OF WHITE SPOT SYNDROME VIRUS MONOCLONAL ANTIBODIES IN THE GUT OF SHRIMP FOR PROPHYLAXIS(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2010) OMKAR V. BYADGI, B.F.Sc.Aquaculture is the worldâ s fastest growing food-production sector, providing protein rich supplement to human beings. Global total production of fish, crustaceans and molluscs has continued to increase and reached 140 million tonnes in 2007. While capture production has stayed around 90 million tonnes since 2001, aquaculture production has continued to show strong growth, increasing at an average annual growth rate of 6.5% from 36.8 million tonnes in 2002 to 50.3 million tonnes in 2007 (FAO, 2009). The value of world aquaculture production was USD 87 billion in 2007 (FAO, 2009). Shrimp continues to be the most important commodity traded in value terms, accounting for 15.4% of the total value of internationally traded fish products in 2007 (FAO 2009). The worldâ s production of shrimp, captured and fanned, is approximately 6 million tonnes, about 60% of which is traded internationally. The worldâ s main shrimp producing country is China with 2.7 million mt, followed by Indonesia, India and ThailandThesisItem Open Access DEMONSTRATION OF AGE OF ANTIBODY PRODUCTION IN INDIAN MAJOR CARP CATLA, (CATLA CATLA) BY MONOCLONAL ANTIBODY BASED HISTOCHEMISTRY(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2009) Divya Kumari.
