Pallab Sarker is a sustainable aquaculture scientist. His research interests involve shifting aquaculture, the world’s fastest growing food sector, to sustainability by redesigning the composition of aqua-feeds because they drive life-cycle environmental effects of aquaculture, both inputs and emissions (pollution). Shifting aquafeeds to more sustainable ingredients is a key part of sustainable aquaculture. He is interested in developing ecological aquaculture principles and practices. The main focus of his current research is to develop a fish-free and crop-free aquaculture diet by combining different species of micro- and macro-algae and developing targeted biochemical manipulations to maximize the diet’s nutrient quality, economic viability, and benefits for environmental conservation.
