    PHYSIOLOGICAL DISTURBANCES IN COMMON CARP (Cyprinus carpio) AS AN INDICATOR OF POLLUTION STRESS

    The 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.

    SUITABILITY OF FARM PONDS FOR AQUACULTURE IN DIFFERENT REGIONS OF DAKSHINA KANNADA DISTRICT
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2011) HARSHA NAYAK, b.f.sc.
    Aquatic systems are those in which the primary medium is water which is inhabited by many organisms. This broad aspect covers a wide variety of habitat types, although they are divided into two separate groups viz, marine and freshwater systems. Research on aquatic system has generally reflected this division viz.. Limnology - the study of inland waters and Oceanography - the study of marine systems, proceeding more or less independently for many years.

    STUDIES ON SOME ASPECTS OF BIOLOGY AND BODY COMPOSITION OF AN EMERGING FISHERY OF PUFFER FISH, LAGOCEPHALUSINERMIS OFF MANGALORE COAST
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2011) KISHOR, K. T., B.F.SC
    The fisheries sector is a source of income and livelihood for millions of people around the world. Marine fisheries are increasingly becoming one of the highly globalized sectors of the world economy. Trade in fish represents a significant source of foreign currency earnings, in addition to the sectorâ s important role in employment, income generation and food security. It should be noted that the declining global catch in the last few years, together with the increased percentage of overexploited, depleted or recovering stocks and the decreased proportion of underexploited and moderately exploited species around the world, strengthens the likelihood that the production of wild capture fisheries will not be able to increase unless effective management plans are put in place to rebuild overfished stocks.

    STUDIES ON GENETIC DIVERSITY IN DIFFERENT STOCKS OF GRASS CARP {CTENOPHARYNGODONIDELLVS} USING RANDOM AMPLIFIED POLYMORPHIC DNA (RAPD) MARKERS
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2011) SAMUEL MOSES, T.L.S., B.F.Sc.
    Aquaculture is one of the fastest growing food producing sectors in the world, with an average annual growth rate of around 8% since 1970 (FAO, 2009). World aquaculture production has shown a tremendous growth from less than 1 million tonnes per year in the early 195Oâ s to 52.5 million tonnes in 2008 which valued at US$98.4billion (FAO, 2010). Per capita supply of fish through aquaculture has also increased from just 0.7 kg in 1970 to 7.8 kg in 2006 (FAO, 2009). India is the second largest aquaculture producer in the world next to China. At present the aquaculture production by India is 3.4 million tonnes (FAO, 2010).

    STUDIES ON BREEDING SEASONALITY OF OTOLITHES RUBER (SCHNEIDER, 1801) ALONG DAKSHINA KANNADA COAST WITH A NOTE ON THE IMPACT OF MONSOON FISHING BAN ON THE LIVELIHOOD OF FISHERFOLK
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2011) RAVI KUMAR, N. D., B.F.Sc.
    Fisheries, a sunrise sector of our economy, play an important role in the socioeconomic development of India, in view of its contribution to the food basket, nutritional and 0.50 million kmâ of continental shelf area. The estimated annual production potential of marine fishery resources of India is 3.90 million tones presently. The contribution of fisheries sector to GDP has been estimated to be 1.24% (Shyam, 2007). Fish is a cheap source of animal protein, has an annual per capita consumption of 9 kg in India as compared to the 11 kg recommended by WHO The marine fish landing of India in 2009 is estimated as 3.16 million tones. The pelagic fishes constituted 52%, demersal fishes 28%, crustaceans 16% and molluscs 4% of the total landings. The west coast and east coast accounted for 56% and 44% respectively (Anon, 201 Oa). stimulating several subsidiary enterprises. Most importantly, fisheries is a source of livelihood for a large section of the economically backward population (Ayyappan, 2006b). The country has 8,129 km of coastline security, sustainable large foreign exchange earnings, generation of employment and income, besides

    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2011) NARASIMHA MURTHY, M. N., B.F.Sc.
    The global production of fish, crustaceans and molluscs has continued to increase and reached 144.6 million tonnes in 2008. While capture production has stayed around 92 million tones since 2001. The 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 52.6 million tonnes in 2008 (FAO, 2011). India ranks second among top ten countries in aquaculture production with an average annual percent growth rate of 5.71 during 2006
