Red tides cannot be eliminated solely through their removal by humans. As long as the functions necessary to the metropolitan area are maintained, red tides will continue to be reproduced. However, by looking at them from another perspective, they could also become a source of nutrition for organisms. While humans cannot directly utilize red tides, they can change them into a form usable as food for filter feeders, such as clams, including the Asari clam. Might it be possible to harness red tides for use in production?
