Cellular, Physiological and Biochemical Basis of Adaptive Response to Variable Osmotic Environments by the River Shad (Tenualosa ilisha)

M. Sc. Thesis: The river shad, Hilsa (Tenualosa ilisha) is the national fish of Bangladesh. This fish spends most of its life cycle (the entire adult stage) in the sea water but migrates to the freshwater rivers for spawning. Following larval development, the adolescent individuals migrate back to the sea for maturation. Within life cycle, Hilsa can tolerate broad spectrum salinity fluctuation (fresh water to full strength sea water). Very few species can tolerate this large scale salinity tolerance. Thus, this thesis aims to investigate different underlying biological (cellular, physiological and biochemical) mechanisms of Hilsa that enable them to tolerate rapid salinity change.
