| 520 | |a“As recommended in Fisheries and Oceans Canada’s (DFO) Steller sea lion management plan, province-wide Steller sea lion surveys were conducted in 2008, 2010 and 2013. The recent survey data are used to analyze trends in pup production and total number of animals at haulouts and on rookeries. Historic and recent information on sea lion abundance in neighbouring waters, particularly the large rookery at Forrester Island in SE Alaska, are also reviewed to assess broader regional trends. The size of the breeding population that would be necessary to support observed pup production on B.C. rookeries is estimated based on life table statistics adjusted for an expanding population. Satellite telemetry data are used to assess diurnal and seasonal haulout patterns, from which survey correction factors are derived to account for animals that are at sea and missed during surveys. Results of winter surveys conducted in B.C. during 2009 and 2010, and an autumn survey in 2012, are presented and the data used to assess abundance and movement patterns of Steller sea lions in B.C. outside the summer breeding season"--Introd., p. 1-2. |
