Experience

My research interests focus on management of soil and water quality in the shrimp pond environment to achieve sustainable production. Nutrient dynamics and budgeting using tracer studies, application of nanotechnology, rejuvenating disused aquaculture ponds, mitigation to reduce greenhouse gas emissions and management of pond health in bio-floc systems are some areas of my work. I have 15 years of experience in soil and water chemistry of aquaculture ponds. My current research areas are the sediment-water interface as a pond health indicator; influence of abiotic factors on the physiology of shrimp; adaptation of shrimp to varying salinities; dynamics of water quality in lined ponds, integrated aqua-agri model and farmer’s livelihood improvement projects.

Projects

  • Development of water and soil health card for environmental management of brackishwater aquaculture systems.
  • National initiative on climate resilient agriculture - impact of climate change on aquaculture and mitigation options for minimising green house gases from the aquaculture sector.
  • ICAR-All India Network Project on Fish Health.
  • Development of environmental parameter monitoring tools and pond treatment technologies for brackishwater aquaculture.
  • Improvement of growth and reproductive traits in penaeid shrimp (Feneropenaeus indicus) through breeding, nutritional and environmental interventions.
  • Technology upgradation and refinement for sustainable development of diversified systems and species of penaeid shrimp.
  • Economics of shrimp ponds, disuse and participatory appraisal of productive use options and policy needs.
  • Technology refinement of nutrient dense nursery rearing and grow-out of Litopenaeus vannamei in periphyton and bio-floc based systems.
  • Optimisation of aerators use to reduce production cost of shrimps under different brackishwater farming conditions.
  • Family farming initiatives in brackishwater aquaculture for livelihood support of communities in Adyar Creek and estuary.
  • Technological backstopping and promotion of sustainable aquaculture in west coast with particular reference to the state Gujarat.
