Nao Thuok, director of the Fisheries Administration, predicted yesterday that Cambodia’s 2010 fish yield would decline by about 30 percent compared to last year due to low water levels. He said the level of the Chaktomok river was 1.67 metres lower than last year, and that Tonle Sap lake was 1.5 metres to 1.8 metres lower. “We certainly are worried about the impact on food security caused by a reduction in the fish yield this year,” he said. “We will continue to fight illegal fishing and arrest perpetrators.”
