“…In E. sinensis culture ponds, cyanobacterial blooms are commonly formed by the following genera, e.g., Microcystis, Cyanobium, Calothrix, Sphaerospermopsis and Cylindrospermopsis [1]. It is well documented that cyanobacterial blooms and their secondary metabolites, cyanobacterial toxins (such as microcystins, anatoxin-a, retinoic acid, microviridins, anabaenopeptins, aeruginosins, microginins, piricyclamides, and cyanopeptolins) can cause a series of problems in aquaculture, such as compromising water quality, altering microbial community assembly, toxic to aquatic animals, and even threatening to human health by bioaccumulation through food chains [5][6][7][8][9][10][11][12].…”
