Petain Xavier Faralahi (22) works as a guard in the sea-cucumber fields of Tampolove village. He does 12 hour shifts, making sure the valuable sea-cucumbers are not stolen from their pens. Faralahi is proud of his role as guardian to 6,000 sea-cucumbers. "I love my job. I'm earning an income and helping my community at the same time. Thefts have gone down a lot", he said.
