The main aim of this phd thesis was therefore to study the spatial and temporal differences and changes in parasite occurrences in freshwater fish from northern norway, and also to explore the importance of three-spined stickleback as a tentative transmission host for salmonid fishes by comparing the. The studies reported in this paper have established the importance of attacking problems of classification of fungal parasites from three angles, namely, morphology, physiology and pathology and these aspects considered interdependenty formed part of a thesis accepted for the msc degree of the university of madras. In this thesis, the life history traits of the ectoparasite argulus coregoni were examined during its life cycle water temperature was a key determinant of temporal patterns of a coregoni population abundance and dynamics neither parasites attached to the host nor egg-hatching were recorded at temperatures below ~10ºc. In this chapter, i summarize what we know about parasite abundance in natural populations i review longitudinal and comparative studies on the presence of parasites in daphnia and other cladocera populations to derive general patterns although no strong patterns have emerged thus far, some trends are apparent. Descriptionit has been difficult to incorporate parasites into ecological studies at the community and ecosystem levels the small size of parasites makes them easily overlooked, and the effects of parasites can often be subtle, indirect and difficult to measure in this thesis i argue that the best way to include parasites into.

However, most of the economic losses are due to sub-clinical effects and although not immediately noticed by the owner, theses can be substantial ( larsen, 2002) in recent study, tibbo (2006) found that parasitic infection of sheep and goats are major factors responsible for economic losses through reduction in productivity.
