An aerial survey, 19 April to 9 May 1965 yielded information on marine animals and birds in the Aleutian Islands and limited areas along the Alaska Peninsula. In areas judged to be overpopulated in 1959, decreased populations were found the Rat and Delarof Islands. Previously unpopulated or sparsely populated areas showed population influx and growth the Near, Andreanof, and Fox Islands, including waters off the SW tip of the Alaska Peninsula. The estimated total number of sea otters in the areas surveyed is about 17, 000.
