Pup production at Scotian Shelf grey seal (Halichoerus grypus) colonies in 2016 / C.E. den Heyer ... [et al.]. : Fs70-5/2017-056E-PDF
“There are few pinniped populations with time series of population estimates that are sufficiently long to illustrate long-term dynamics. One of the longest series of estimates of pinniped pup production comes from Sable Island, Nova Scotia. Since 1962, the number of grey seal (Halichoerus grypus) pups born on Sable Island has increased exponentially. The other major grey seal breeding colony in the northwest Atlantic is located on the sea ice and small islands in the southern Gulf of St. Lawrence. In addition to these large colonies, there are a number of small grey seal breeding colonies on near-shore islands along the Atlantic Coast of Nova Scotia and in the Gulf of Maine, some of which have been established more recently and have increased rapidly. In Canada, three management units are recognized based on the location of breeding colonies: Gulf of St. Lawrence (GSL), Coastal Nova Scotia (CNS) and Sable Island. Here we report on the 2016 aerial-photographic surveys of grey seal pup production at Sable Island and the islands along the Atlantic coast of Nova Scotia, including Hay Island off Cape Breton and four small islands in southwest Nova Scotia"--Introd., p. 1.
