Mahmudul Hasan is currently pursuing his BSc degree in Marine Sciences at University of Chittagong. His research interests lie in the field of coastal and marine aquaculture. Particularly, he is interested to contribute in technological advancement for enhancing coastal and marine fisheries production that reduce pressure on wild catches and promote the blue economy of the country. Currently, Mahmudul is working with OiLAB aquaculture research team under IMTA innovation program, who are investigating to develop sustainable indoor vertical carb production system using recirculating aquaculture technology (RAS). This research aims to revolutionize crab culture by achieving high production rate with economic profits through a sustainable and controlled close system that can be replicated in any place, even at indoor household settings. This research is designed to mitigate the challenges posed by traditional crab farming such as space limitation and water quality management. Mahmudul is dedicated to serve his country by addressing pressing challenges in coastal and marine aquaculture and promoting the sustainable practice for future generations.
