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.ThesisItem Open Access STUDIES ON BENTHIC DETRITAL AGGREGATE FORMATION IN CULTURED SHRIMP POND(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2012) PRA VEEN, G. P., B. F. ScIndia is a vast country with having varied and enriched natural resources. The natural resources like freshwater, marine water and the brackish water are important in production and development of resources. India has huge potential brackish water resources and these brackish water resources include estuaries, coastal lagoons, mangrove swamps and coral reefs supports a varied biological resources, such as fishes, prawns/shrimps, crabs, mussels, (clams, cockles, and oysters), lobsters, and other with their seed resources as well as sea weeds. India has 1.30 million ha. brackish water area suitable for aquaculture. (Ghosh, 2010). Out of which, at present about 1.41 lac. ha. area is presently under aquaculture (traditional, improved extensive and semi-intensive systems). And the estuaries covered along North Kanara district are Kalinadi, Aghnashini and Sharavati.ThesisItem Open Access STUDY OF CHAETOGNATHS AND JELLYFISHES IN THE COASTAL WATERS OFF MANGALURU, DAKSHINA KANNADA(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2016) PEMA CHOTTEN WANGJA, B.F.Sc.India has a coastline of 8129 km and the coastal zone serves as a link between ocean and land marginsThesisItem Open Access STUDY OF CHAETOGNATHS AND JELLYFISHES IN THE COASTAL WATERS OFF MANGALURU, DAKSHINA KANNADA(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2016) PEMA CHOTTEN WANGJA, B.F.ScIndia has a coastline of 8129 km and the coastal zone serves as a link between ocean and land margins.ThesisItem Open Access OXIDATIVE STRESS RESPONSES IN COMMON CARP (Cyprinus carpio) EXPOSED TO ORGANOPHOSPHOROUS PESTICIDE(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2012) PADMANABHA, A., B.F.ScThe presence of a xenobiotic compound in an aquatic ecosystem does not, by itself, indicate injurious effectsThesisItem Open Access PHYSIOLOGICAL DISTURBANCES IN COMMON CARP (Cyprinus carpio) AS AN INDICATOR OF POLLUTION STRESS(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2011) MUTTAPPA KHAVL, b.f.Sc.Aquatic ecosystems are being contaminated rapidly by xenobiotics of variegated nature. The impact of aquatic pollution is so alarming that it has attracted even politicians and administrators apart from scientists and technocrats. Sincere efforts are seldom made in developing countries to evolve methods for pollution monitoring and control, in parallel with the rapid advancements in industry, spreading of urban settlements and technological gallops. Methods for effective abatement of pollution are necessary and proper implementation of legislation and enforcement of existing regulations are highly essential considering the deleterious effects likely to occur to the healthy aquatic system.
