RESEARCH INTERESTS

AQUATIC ECOTOXICOLOGY: My primary research interest is aquatic stress ecology, aquatic ecotoxicology in particular. I have lead & supervised researched projects on impacts of pesticides and pharmaceuticals on different aquatic life forms. To be more specific, my researches include impacts of pesticides from agriculture and pharmaceuticals from industries & hospitals in altering physiology (hematology, organ pathology), reproduction (reproductive toxicity [intersexuality, sterility, sex change], fertilization & hatching rate) and development (mortality & developmental deformity during embryonic & larval development) of different fish species. Other related areas of interest include impacts of- (a) agro-pesticides on designed aquatic microcosm, (b) aquatic heavy metal pollution on physiology of aquatic hydrophytes, (c) heavy metal pollution in waterbodies and bioaccumulation in aquatic life forms. 

CLIMATE CHANGE IMPACTS: Due to my interest looking into the environmental stresses in the aquatic ecosystems, I have supervised researches towards understanding impacts of different climate parameters (e.g., salinity, temperature) in altering physiological functioning of fish and aquatic hydrophytes.

AQUATIC CONSERVATION BIOLOGY: Application of reproductive biology protocols towards conservation & management of commercially important and threatened fish species is another area of my interest. As a result, I have long been working to identify sea gonadal cycles and natural breeding seasons of threatened fish species from the largest ‘haor’ basin (natural saucer-shaped depression renewed with water every monsoon) of Bangladesh (called ‘Sylhet Basin’). These information are providing important guidelines to the related government departments to maintain correct ‘fish ban’ season as a part of conservation & management of the resources. Moreover, I have successfully bred a threatened freshwater eel (Gangetic Mud Eel, Monopterus cuchia) in captivity. In 2015, research outputs from my research has impacted national level policy decision making towards management of the largest single species openwater fishery of Bangladesh – the Hilsa Fishery.
