Seven fishermen have been arrested and 22 fined for illegal fishing during spawning season in a protected area, Fisheries Administration Director Nao Thuok told the Post Wednesday. "The arrested fishermen were sentenced to one year imprisonment, and 22 others were fined 27 million riel (US$6,750)," Nao Thuok added. The National Assembly in 2006 adopted a law prohibiting fishing during the spawning season, which runs from June to October, to preserve fresh water natural resources. Nao Thuok said that this year the Fisheries Administration, in collaboration with provincial authorities, has cracked down on more than 600 cases of illegal fishing across the country. To date, fisheries officials and authorities have burned 73,162 metres of fishing nets and other equipment. More than two million fish have been confiscated from fishermen and released back into the sea, Nao Thuok said.
