ThesisItem Open Access STUDIES ON PHYTOPLANKTON IN RELATION TO TIDAL RHYTHM AND HYDROGRAPHY OF GURPUR ESTUARY, DAKSHINA KANNADA(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2007) CHETHAN N., B.F.ScScientific studies of estuaries have assumed a greater importance due to more than one reason. In the viewpoint of geologist, though most estuaries are epimeral, nevertheless are effective transporting agents for the terrigenous sediments in to the adjacent sea. Geo chemists consider that the chemical nature of the adjacent sea including the concentration of certain important trace elements and their equilibrium are to a great extent controlled by the estuary. In fact it is the biologists who have long before recognised estuaries as a pathway for anadromous and catadromous varieties of fishes. They have also known the estuaries as nursery grounds for various commercially important fin fishes and shellfishes. Coastal oceanographers and harbour engineers have recognised not only the impact of the estuaries in the coastal processes of erosion and sedimentation but also, the environments which preserve and provide various living and non-living resources.ThesisItem Open Access STUDIES ON MEIOBENTHOS IN RELATION TO SELECTED SEDIMENT CHARACTERISTICS IN GURUPUR ESTUARY, MANGALORE(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2007) AYYAN KUMAR. V., B.F.ScThe world oceans and the inland waters occupy 71% and 0.5% of the earthâ s surface respectively. The transition zone between these two distinctly different water bodies is known as estuaries, whose characteristics are influenced by the freshwater drainage from the land and the incursion of salt water from the adjoining sea. Thus, an estuary is defined as a semi-enclosed coastal body of water, which has a free connection with the open sea and within which the sea water is measurably diluted with freshwater derived from land drainage (Pritchard, 1967).ThesisItem Open Access SOME ECOLOGICAL ASPECTS OF THE CLAM BEDS IN GURPUR ESTUARY, DAKSHINA KANNADA(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2008) RAJ ANNA J., B.F.ScEstuaries are highly dynamic, a regular mixing of seawater with fresh water and forms an important buffer zone between the river and the sea. Estuary is defined as the tidal mouth of a river. An estuary is â a semi-enclosed coastal body of water which has a free connection with the open sea and within which the sea water is measurably diluted with fresh water, derived from land drainageâ ? (Prichard in 1967). Estuary forms an important habitat of the aquatic environment with unique properties. Although, these unique properties are common to all the estuaries in the world, each individual estuary retains some of its own special characteristics, which are determined by topography, tidal range and local climate conditionsThesisItem Open Access DISTRIBUTION AND ABUNDANCE OF ZOOPLANKTON IN THE COASTAL WATERS OF PADUBIDIRI, UDUPI DISTRICT(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2009) RESMI, S., B.F.ScThe Earth is unique among the known celestial bodies as it has water that covers threefourths of the surface of this planetThesisItem Open Access MACROBENTHIC COMMUNITY STRUCTURE IN RELATION TO SEDIMENT CHARACTERISTICS IN THE COASTAL WATERS OF PADUBIDRI, UDUPI DISTRICT(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2009) RAJESHWARI VITAL B.B. F. ScThe Indian sub-continent has a vast coast-line of around 8129 km having an immense fishery Potential especially in the demersal zone.ThesisItem Open Access STUDY ON DISTRIBUTION OF TOP SNAIL TELESCOPIUM TELESCOPIUM IN MANGROVE ALONG NETHRAVATHI ESTUARY, MANGALORE(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2010) PRASHANTH, J.M. B. F. ScMangrove ecosystems (mangal) are among the worldâ s most productive ecosystemsThesisItem Open Access PHYTOPLANKTON DYNAMICS IN THE COASTAL WATERS OF MURUDESHWAR, KARNATAKA(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2007) MOHAN A.B.F. ScThe ocean is the largest and the most stable of all biomes which covers about 70% of earthâ s surface and even which is responsible for the stabilization of various processes like the overall heat and temperature distribution in the earthâ s atmosphere. The coastal region is basically the area of wave and tidal actions and possess more dynamic ecosystem than the open sea. The Indian coasts are complex regions as these are greatly affected by the monsoons, river run off, currents, tides and land based pollution (Qasim, 1992). Hence, these coastal waters are rich in nutrients and exhibit the highest productivity and biodiversity. The primary productivity from coastal zone accounts for 14% of the total ocean productivity and contribute 90% of the global marine fish catch.ThesisItem Open Access NUTRIENT PROFILE OF SEDIMENT AND WATER IN SELECTED SHRIMP PONDS(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2006) MANJUNATHA, R. NAYAKA, B.F.Sc.Shrimp farming is a major aquaculture industry in tropical and subtropical regions around the world. The shrimp production in 1987 was about 2.40 mint which increased to 4.20 mmt. in 2000. (FAO, 2004).ThesisItem Open Access PHYTOPLANKTON DYNAMICS IN THE COASTAL WATERS OF PADUBIDRI, UDUPI DISTRICT(Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2009) Ms. MEGHANA P.N., B F ScOver ninety percent of the planetâ s living and non living resources are found within a few hundred kilometers of the coast.
