520 | |a"In June 2019, a helicopter survey was conducted to determine harbour and grey seals distribution and abundance in the Estuary and Gulf of St. Lawrence. A total of 5,714 harbour seals and 14,691 grey seals were counted at haul-out sites. In the estuary, 2,140 harbour seals and 839 grey seals were counted, representing a significant increase from surveys conducted in 1995-96 and 2000, particularly in the upper estuary for grey seals and in the lower estuary for harbour seals. In the Gulf, grey seals were dominant (13,852 grey seals versus 3,574 harbour seals). Counts were higher than in previous surveys, due to both a larger survey area being covered in 2019, and a greater number of animals present in areas covered during previous surveys. The 2019 survey provides the first comprehensive count and spatial distribution data for harbor seals and grey seals over the entire Estuary and Gulf of St. Lawrence. Combined with information from similar surveys conducted in other regions in eastern Canada, these data will serve to improve knowledge of the population size and distribution of both species in this area"--Abstract. |
