5203 |a"Distribution of grey seals was estimated in May, August, November and January from aerial surveys of the Gulf of St. Lawrence. The only major concentrations observed were the 'moulting' or haul out on Anticosti Island in May and the 'pupping' in the Northumberland Strait area in January. Other minor concentrations occurred in southwestern Newfoundland in August and on Deadman's Island in November and January. Seal distribution followed very closely upon the boundaries of National Parks, inaccessible islands and rugged cliff beaches. One factor probably affecting distribution was the presence of people on beaches which were inaccessible before 'ATVs' and skidoos. The maximum estimated number of seals at the time of the January survey was 7,000, while the maximum observed on any one flight was approximately 2,300. This suggests a population in the Gulf of between 5,000 and 10,000 animals"--Abstract, page iii.
