The Department of Fisheries issued a ban on imports of "trey chap,", a
fish species related to piranha, on December 29. They are imported from Vietnam to
be bred in local ponds for food. It is feared that if they enter natural water sources
they could damage local fish stocks and pose a threat to humans and animals. Department
director Nao Thourk estimated about 20,000 fish had already been imported. Fishery
officials have been given orders to destroy the fish.
