Microalgal cultivation in open ponds is emerging as a sustainable solution to combat the global food and energy crisis. However, contamination by unwanted microbes, particularly predators, in open cultivation leads to a clearance of microalgae. An early predator detection tool is thus required for effective pond culture management. Unlike routinely used offline monitoring methods, we report three novel and non-invasive markers that can be immediately extended for on-site screening of predators. The thesis demonstrates effectiveness of levels of non-photochemical quenching, total-ammonia nitrogen and FTIR-based (1363 cm-1) features as markers of grazing by a dinoflagellate predator on a green alga prey.
