In those days fishing harbors were strictly controlled, and usually no vessels were allowed in or out after 10 p.m. Hence fishermen were afraid of returning too late, and sometimes when they were halfway home they would cut the line on a shark in order to speed up and make it back before the curfew.
因為，那時候的漁港管制很嚴，一般在晚上十點鐘以後，就不准進出，所以漁民為了怕耽誤進港時辰，有時會在半途，忍痛割斷繩索，放掉到手的獵物，以求加速，趕在宵禁前入港。
