During a five-hour operation that lasted until 5am on Saturday, the team seized more than 300 of the collapsible traps, which are classified as destructive fishing gear. Local fishermen were earning more income, and the number of illegal fishing boats had dropped to about 500, said Mr Pornsak. However, the number of unlicensed fishing boats has since risen to 2,000 and many of them were fitted with illegal traps, he said.
