    • AFSC/NMML/CCEP: Harbor seal demography in Washington; capture, tagging, branding data from 1981 to 2007

    Metadata Updated: April 1, 2024

    The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) in collaboration with Washington Department of Fish and Wildlife captured and sampled Pacific harbor seals (Phoca vitulina) to study the demography of this species in Washington. This database provides capture, recapture, branding and resighting information for harbor seals in Washington from 1981 to 2007. Datasets include: Captures, Recapture, and Resight. Captures and Recapture information includes speno, date, age-class, age qualifier, sex, weight, length, health, tag number, brand number, location for all age classes and axial girth for pups and subadults. It also notes if samples were taken for disease screening (blood and swabs), contaminants (blubber), genetics (skin) and if animals were instrumented and with what type(s) of instrument. Resights information includes speno, date, tag, brand, reproductive information, location.

    Lineage Capture methods were by beach seine or tangle net or 'run and grab;' methods are described in Jeffries et al. 1993. Branding in south Puget Sound took place between 1993 and 2011. Hot brands of 1 to 3 digits, using rolled stainless steel branding irons, were applied with even pressure for 3 to 4 seconds on both sides of subadult and adult animals that were physically restrained. Only pups greater than 20 kg were branded. After 2009. pups were branded on one side only. Harbor seal resights were made in south Puget Sound at Gertrude Island, Eagle Island, Woodard Bay, and Commencement Bay on land and from small boats using blinds, boats, and vehicles provided by Washington Department of Fish and Wildlife. Observations of tagged and branded harbor seals took place at least 3 days/week at Gertrude Island between 15 June and 15 September and at least 1 day/week 16 Sept to 1 November from 1994 to 2011. After 2011, resighting observations were more irregular.
