ANGKOAL, Cambodia - For Ung Bun, a 39-year-old fisherman from Cambodia's southern Kep province, the days when he would come home with plentiful catches of flower crabs appear to be long gone.
He later took three gravid crabs - females laden with eggs - out of a bucket and released them back into the sea. According to data from the University of Maine's Climate Change Institute, temperature spikes above normal have become increasingly common in oceans along Cambodia's coastline since 2010. The day he caught just one crab only to let it go, he earned just 40,000 riels for fish he caught, money he used to pay for a litre of gasoline for his boat. The second-generation fisherman also has two young daughters whose school fees amount to 1 million riels a month and owes US$10,000 on the bank loan he took out to buy the boat.
