Assisted by aircraft flying over the area, wildlife rescuers resumed their search Saturday in the the waters off Catalina Island for a distressed blue whale.
The 80-foot mammal, which had become entangled in what's believed to be heavy fishing line, was last seen late Friday between Los Angeles Harbor and Catalina, said Jim Milbury, a spokesman for the NOAA Marine Fisheries Service.
Milbury said officials had asked pilots in the area to keep any eye out for a red buoy.
Crews had earlier attached the buoy to the line to discourage the whale from diving and to better track the animal.
