Over the past few decades, toxic red tides have had a negative effect on human health, the fisheries industry, and coastal environments, resulting in significant economic losses. We demonstrate a method for the control and suppression of harmful algal blooms (HABs) through selective algal lysis. The method involves the algicidal effect of HABs with aminoclay and has negligible effects on non-harmful phytoplankton, zooplankton, and fish farmed. The use of positively charged colloidals of aminoclays produced cell lysis in HABs within several minutes due to the ammonium characteristics of the aminoclay and the electrostatic attraction between the clay nanoparticles and the algal cells. We show that selective algal lysis by water-dispersed aminoclays in batch mode produces 100% cell death. In contrast, treatment with yellow loess caused algal flocs with little cell lysis. The amount of aminoclay loading needed for the mitigation of HABs is at least ten times lower than that of the conventional yellow loess used as a mechanical treatment.
