Do we have to force Bukang-i out?

Won't it leave on its own once the weather gets colder?
'Bukang-i' ultimately failed to return to the sea... A 3-hour 'hide-and-seek' with rescuers as sirens blared. Daum | Hankook Ilbo. 'Bukang-i,' the shark in the artificial waterway of the Busan North Port Waterfront Park, was unable to return to the sea. This was because the shark continued to evade the vessels engaged in the rescue operation and remained in the waterway. On the morning of the 29th, the Coast Guard and fire department deployed three vessels to the waterfront park's waterway to send the shark back to the sea, operating water pumps and spraying thick streams of water in front of the vessels. Two rescue boats followed behind these vessels.
