Seaweed Could Solve One of Aquaculture’s Biggest Pollution Problems
Ben Sullivan
Every yellowtail snapper excretes ammonia. It cannot help doing so; it is a metabolic inevitability, the nitrogen-rich byproduct of a fish eating, breathing, living at commercial density in a tank on Virginia Key, Florida. In a conventional aquaculture operation, that ammonia accumulates in the effluent water until it becomes a problem, sometimes a serious one, for the marine environment downstream. What researchers at the University of Miami have spent the past several years working out is...
