Keywords: Steller sea lions, community-based research, ecological studies
1. Objectives: This project seeks to involve a community of resource users in the collection of sightings data and samples needed to assess the distribution and diet of Steller sea lion predators and competitors in the Gulf of Alaska.
2. Rationale:

Coastal communities are being socially and economically affected by Steller sea lion protective measures currently founded on limited data. This project will provide the opportunity for residents and mariners to contribute sightings and samples needed to fill these data gaps and refine the "best available data" on Steller sea lion ecology.

3. Methodology: I will promote and facilitate reporting of whale sightings by pilots/mariners and collection of biological samples from commercial fishermen. These collections will form a critical component of marine mammal research being conducted by UAF’s Gulf Apex Predator-Prey (GAP) study.
4. Benefits:
This project will provide both biological and social benefits. It will inexpensively facilitate collection of valuable biological data and samples needed to improve our knowledge of Steller sea lion trophic interactions and refine the assumptions upon which fisheries management plans are based. By soliciting and facilitating public involvement in this research, the project will secondarily generate a grassroots-level sense of stewardship, understanding of, and involvement in research on Steller sea lion ecology.
5. Accomplishments: Wynne has already established a reputation, rapport, and working relationship with many of Kodiak’s marine resource users that will form the basis for this network of volunteers. Numerous Kodiak residents have repeatedly and effectively demonstrated their support for the concept and operations of UAF’s fully funded GAP study and have already volunteered information and biological samples for this project.

Samples

Wynne involved a variety of resource users in the collection of biological samples to be used in the study of trophic-level interactions between Steller sea lions and other apex predators (including humans) in the Kodiak area.

  1. Wynne worked with commercial fishermen and processors to collect samples needed to assess diets of sharks and other piscivorous fish in the Kodiak area; distributed results of the 2001 study to individual participants along with permit and request to collect in 2003; collected stomachs from sport-caught salmon and halibut processed in Kodiak.
  2. Wynne trained 25 NMFS-funded observers in proper identification, documentation, and sampling of marine birds and mammals taken as bycatch in Kodiak commercial set gillnets. Received harbor porpoise (2) and bird (35) carcasses from which stomach content, fatty acid signatures and stable isotopes will be sampled and used to document prey use by these apex predators.
  3. Coastal residents reported five dead and beachcast marine mammals (gray whale [1], Cuvier's beaked whale [1], harbor porpoise [1], and Steller sea lions [2]) to the PI, two of which were salvaged or sampled for later necropsy.

Sightings

Marine mammal/whale observation is a public/tourist attraction of growing popularity in the Kodiak area. Data collected from the public can also support research on the distribution and diets of these apex predators. During this reporting period, Wynne helped publicize a 3-day public census of killer whales for the North Pacific Universities Marine Mammal Research Consortium (NPUMMC); received whale sightings from Kodiak residents, commercial fishermen, U.S. Coast Guard vessels, coastal homeowners, recreational boaters, and charter vessels; and provided identification materials and logbooks to Kodiak air charter pilots in order to document their whale observations and track distribution.

Wynne presented a visual description and aid to identification of whales common to Kodiak to 65 Kodiak residents during WhaleFest 2002. This allowed the community's contribution of whale sightings.

Wynne was interviewed for stories on observed killer whale-sea lion interactions in Kodiak Harbor that were published in the Anchorage Daily News and Kodiak Daily Mirror.

Wynne took a film crew into the field to document UAF whale and Steller sea lion research for inclusion in a "nature news magazine-style" television show to be broadcast fall 2002.

6. Students Supported: None.
