17353 Alaska Phocid Food Habits Data Set Published / External 71890 Alaska Phocid Captures and Specimens Collected Project In Work Relatively little is known of the diet and foraging behaviors of the four species of ice-associated seals (ribbon seal, bearded seal, spotted seal, and ringed seal) and harbor seals in Alaska. What is known comes largely from stomach contents of animals harvested during subsistence hunting near coastal communities. Diet and foraging ecology are likely highly sensitive to the availability of suitable habitats and sea ice conditions. They may be particularly vulnerable to climatic change and other disruptions from more direct anthropogenic effects such as offshore oil and gas development. Our ability to predict and manage for such impacts, however, is limited by our inadequate knowledge of seal ecology. This database contains diet data obtained by scat samples from seals across a variety of research projects. Scat samples were collected from ribbon and spotted seals in the pack ice in the Bering Sea during April, May, and June of 2007-2010, and 2014. The diet data in this database were obtained by analyzing otoliths from these scats. Scat samples have also been collected from harbor seals from Lake Iliamna in July-August 2015, and from the Aleutian Islands in September 2015. Diet data based on otoliths from these scats will also be recorded in this dataset. The purpose of this dataset is to store all food habits data collected from various Polar Ecosystem Program research projects. To fulfill its stewardship mandates described by the Marine Mammal Protection Act, NMFS is required to have information on these species, including abundance, population trend, and extent of interactions with fisheries, seasonal movements, and distribution and harvest pressures. Basic biological data are limited for ribbon and spotted seals in the wild, and food habits data collected from live animals in the wild are particularly scarce. Food habits data are essential to helping understand and evaluate how ice-associated seals could be affected by a changing environment. Ziel, H.Z., J.M. London, M.F. Cameron, and P.L.

Scat samples were collected from ribbon and spotted seals on the pack ice in the Bering Sea, and from harbor seals on the coasts in Lake Iliamna and in the Aleutian Islands. Scats were processed in the lab, and hard parts (otoliths and bones) were collected from each scat sample. Otoliths were identified to the lowest possible taxon and are recorded in this dataset. gov.noaa.nmfs.inport:17353 SysAdmin InPortAdmin 2012-12-21T17:17:08 SysAdmin InPortAdmin 2026-03-04T19:17:17 2024-04-03 Alaska Fisheries Science Center AFSC 7600 Sand Point Way N.E., Building 4 Seattle WA 98115 USA https://www.afsc.noaa.gov 0700-1700 Pacific Time 1001 Public No No 2018-11-27 1 Year 2019-11-27 none marine mammal seal ribbon seal spotted seal Kingdom Animalia Genus Phoca Species largha Spotted seal Genus Phoca Species fasciata Ribbon seal
