A/Prof. Sasi Nayar

Biography

Dr Nayar leads the Aquaculture program and manages the Algal Production Group. He has for over two decades led an applied, industry focused, research program developing micro- and macroalgal production systems for high value applications of the sustainably cultivated biomass. Using a multidisciplinary and collaborative approach, Dr. Nayar and his team tackle significant scientific and societal challenges.

These include bioremediation of wastewater, bio assimilation of nitrogen, carbon and phosphorus, valorisation of aquaculture waste streams, alongside advancing algal aquaculture for novel marine bioproducts. Their efforts are closely integrated with government and industry partners to ensure alignment with practical needs and sustainability goals.

Dr Nayar has a deep commitment to advancing scientific knowledge and its practical applications in addressing pressing environmental and economic challenges. His leadership in algal biology and aquaculture underscores his pivotal role in driving innovation and sustainable development within these fields with the ultimate focus on advancing the South Australian Aquaculture industry.

This study explores how the temperate seagrass Zostera nigricaulis absorbs and redistributes nitrogen in the nutrient-sensitive ecosystem of Port Phillip Bay. Using stable isotope tracers and diver-deployed benthic chambers, researchers measured uptake and translocation of both a…
This report investigates the resilience of Zostera seagrass in Port Phillip Bay, a vital habitat supporting biodiversity and coastal stability. Researchers examined environmental drivers such as nutrient availability, sediment type, and wave exposure, which influence the persiste…
