1. A brief survey of cyanobacteria and algal bloom detection Cyanobacteria are a diverse group of photosynthetic bacteria encompassing 1,600 species that can form dense and sometimes toxic blooms in freshwater and marine environments, and thereby represent a threat to natural ecosystems and water quality (Rastogi et al., 2015; Huisman et al., 2018). The toxic cyanobacterial blooms (cHABs) are of particular concern to human and animal health.
