Harmful cyanobacterial blooms are a major problem in freshwater aquaculture. Such blooms occur regularly in aquaculture ponds, particularly under high nutrient loads and elevated environmental temperatures. Secondary metabolites produced by cyanobacterial cells during such blooms often result in the accumulation of unpleasant off-flavors in fish and other aquatic food species. Some cyanobacterial species are also capable of producing potent hepatotoxins that, when accumulated in fish tissue, may render it unsafe for consumption. Here we report the efficacy of biocidic nanoparticles in controlling such blooms under laboratory conditions, and the developing of a novel microfluidic experimental platform that will allow us to gain mechanistic insights into the activity of these nanoparticles, and how they may be improved to specifically target harmful phytoplankton species in the environment.
