TOKYO, Jan 31 (IPS) - Japan, a voracious consumer of marine resources, is now discovering that the drastic depletion of its own fish stocks is linked to the loss of underwater seaweed colonies caused, in turn, by rising sea temperatures.
''It's no exaggeration to say that Japan faces a critical situation when describing the rapid decline of marine supply in its domestic waters that is linked to seaweed loss. Tengusa (seaweed) provides food for marine species,'' says Tomohiro Takase, head of the fisheries department at the Hachijojima municipality.
Hachijojima island, situated 300 miles (482 km) south of Tokyo, is now reporting the drastic decline of abalone, a marine resource that fetched high prices and provided a lucrative income for fishermen living on the island.
Takase says regular catches of around 20 tons per year have now dropped to less than one ton, leaving fishermen to face a gloomy future.
''The situation is alarming. Investigations have shown widespread seabed desertification or the surf burnout phenomenon, across Japan. In Hachijojima the loss of tengusa covers most of the waters surrounding the island,'' explained Takase.
