Nila Rekha. P. Ms. Dr
Designation : Principal Scientist
Discipline : Soil and water conservation engineering
Division : Crustecean Culture Division
Specialization : Soil and water conservation engineering
Research areas:
  • Environmental impact, salinity intrusion in coastal watershed using GIS and modelling.
  • Shrimp farm mechanization with renewable energy , design of automatic feeder and RAS.
  • Wastewater management ,Seaweed bioremediation for brackishwater aquaculture.
Brief profile:

After taking masters in Agricultural engineering in 1995, registered for my PhD in the topic Impact assessment of effluent irrigation using GIS and RS at Center for water resources, Anna university . Subsequently joined CIBA in 1997 and worked on various issues of brackishwater aquaculture pertaining to the environment and aquaculture engineering. In the mean time completed PhD in Civil engineering in 2004. I currently work in Crustacean Culture Division in CIBA. I have worked on seepage control in brackishwater ponds , soil and water quality management of shrimp ponds , Environmental impact assessment of shrimp farming, using GIS , RS and spatial modelling , salinity monitoring , mapping using hyperspectral remote sensing , discharge water treatment using mangroves ,and seaweed bioremediation , RAS , BMP and biosecurity aspects of both hatchery and shrimp farms , I have contributed to the sustainable aquaculture by designing an automatic feeder for L. vannamei farm . I have interests in shrimp farm mechanization , environmental management of shrimp farms, seaweed culture, GIS and hyperspectral mapping and renewable energy sources for aquaculture.
