- Initiated - Climate change impact on proglacial freshwater ecosystems functioning
- The myth that animals in tropics do not use day length to time seasonal phenomenon (viz., reproduction, moulting) demolished.
- Basic concepts in photoperiodism & hormone (thyroid) action challenged.
- Radioimmunoassay standardized for thyroid hormones in animal sera first time in the country.
- First data base on thyroid hormone profiles for management of Goitre & Iodine Deficiency Disorders in Himalaya–a health hazard in mountains.
- Erstwhile circulating protein bound iodine (PBI) universally used in thyroid diagnosis first demonstrated to be an erroneous parameter.
- First unequivocal evidence provided for the hormonal basis of bird migration.
- A novel approach to study Himalayan biodiversity commenced integrating molecular, phenotypic (morphological, osteological), behavioral & ecological aspects.
- First DNA finger prints of Himalayan fish species, registered with NCBI, USA (in collaboration with CCMB, Hyderabad).
- Application of Bioinformatics Tools to distribution & evolution of Himalayan fauna, Human tribes, Incidence of diseases.
- Role of pheromones in reproductive behaviour and physiology of fish has been evaluated for the first time in Indian Subcontinent. Studies carried out include the isolation, identification, chemistry, release mechanism & mode of action of sex pheromones in fish.
- Successful development of hatchery and stocking facilities for hill stream fishes including the Snow trout (Schizothorax richardsonii) and Himalayan Mahseer (Tor putitora).
- Morpho-histological and histochemical basis of organogenesis from Pre to Post flexing stages in hill stream fishes have been revealed.
- DNA isolation and sequencing of Glyptothorax spp. have been accomplished.
- Strong knowledge base on the fishery biology, ecology and population dynamics, over a period of more than two decades, has been developed to assess the status of the Himalayan mahseer, a threatened fish species, to compliment conservation.
- Based on evaluation of microhabitat characteristics of early life stage (0+ Year) of threatened Himalayan Mahseer, habitat suitability for its conservation recommended.
- Inventorization of the aquatic biodiversity of Garhwal Himalaya, organisms of interest being benthic diatoms, benthic macroinvertebrates and fish.
- Community structure, productivity and distribution of macroinvertebrate benthos at watershed and catchment scale in the Himalayan region revealed.
- Study on molecular characterization of benthic macroinvertebrates initiated.
- Pioneering study to determine the ecological (including trophic and saprobic) state of streams and rivers vis-à-vis land use across all major river basins of the Uttarakhand State.
- Developing strategies for sustainable use of mountain fishery resources.
