A resident of India. I was engaged in teaching, research and extension for 33 years at the College of Fisheries, Mangalore, initially under the University of Agricultural Sciences, Bangalore and subsequently Karnataka Veterinary, Animal and Fisheries Sciences University, Bidar. Superannuated as Dean (Fisheries). Had higher education in Mysore University and Delhi University and did post-doctoral studies at the University of Stirling, U.K. I was a consultant for Brethren Colleges Abroad, USA and WorldFish, Malaysia for one year each. I conceptualized and implemented a project on eco-friendly feeding strategies for enhancing production of Amazonid fish in Brazil
My research interests mainly include Aquaculture, Nutrition and Fish Breeding. I have 36 years of research experience and have carried out research on composite fish culture, periphyton-based aquaculture, diet development and evaluation for fish and prawns and induced breeding of fish. Completed a European Union-funded project on periphyton-based aquaculture with 3 other partners viz. Institute of Aquaculture, Stirling U.K., Wageningen University, The Netherlands and Bangladesh Agricultural University, Mymensing. CNPq funded the project on eco-friendly feeding strategies for enhancing the production of Amazonid fish operated by me at INPA, Manaus, Brazil.
