Many are migrant workers abandoned by their boat captains after the government passed a moratorium on foreign fishing five months ago, according to the International Organization for Migration in Indonesia, which released the figure yesterday.
However, others have been trapped on the islands for years, after being dumped by fishing boats or escaping into the jungle.
"This is the worst moment in our life right now," one former slave told the AP, which is not releasing the names of the men for their safety. "It is even worse than being in hell. We have to work every day to survive. ... There is no hope for us any more."
Many of the stranded are Burmese men who went to neighboring Thailand in search of work. They were taken by boat to Indonesia, which has some of the world's richest fishing grounds. Others left behind are Cambodian and a few from the poorer parts of Thailand.
"It is reasonable to expect many are victims of trafficking, if not outright slavery," he said. "But for the first time in possibly several years, their feet are touching dry land and there is a real possibility for them to go home, once we and the authorities locate and process them."
About a quarter of the men are in Benjina, a town that straddles two islands in the Maluku chain, according to an Indonesian official who recently visited the area. These men, some abandoned five, 10, even 20 years ago, load and unload fish off boats for food and pocket money, or cut and sell logs in the forest.
