The efforts to clean up the sea has out an adverse effect on the fishing industry in Hyogo, Okayama and Oita prefectures along the Setonai inland seaboard. It has been said that the sea is now too clean for the fishes to survive.

Researchers have found that the natural levels of nitrogen and phosphorous in the salt content of water needed for the nutritional growth of healthy plankton have diminished. The cleaning has affected the natural ecosystem of the sea. Without plankton, the major nutrition for many small sea animals cannot survive as the while food chain is disrupted to the point of great loss to the fishing industry.
