Korean Scientist on the 'Tianchi monster'

A North Korea scientist has suggested that the images of the 'Tianchi monster' captured by a Chinese photographer are large trout, the offspring of fish introduced into the lake by North Koreans 40 years ago. From the news:

"77-year-old Kim Li-tae said during an interview with the Choson Shinbo, a newspaper published by the General Association of Korean Residents in Japan, that he was one of the North Korean researchers who released nine trout into Tianchi Lake, located on Changbai Mountain, on July 30, 1960. At a later date they released other species of fish such as carp and mosquito fish into the lake." ...
"In 2000, the Korean researchers did experimental tests on 'Tianchi trout' found in shoal waters that measured 85 centimeters in length and weighed 7.7 kilos, but they've never been able to test trout from the deeper waters of Tianchi Lake. The 'Tianchi monster' that Chinese photographer Zhuo Yongsheng, who works for a local TV station run by the administration office of the nature reserve at Mount Changbaishan, Jilin Province captured on film last month, might be a 'Tianchi trout' from the deep of the lake, Kim said."
