Biology of the ringed seal (Phoca hispida) in Alaska, 1960-2010 : Final report to National Marine Fisheries Service
Abstract/Contents
- Abstract
- The Alaska Department of Fish and Game (ADF&G) has been monitoring the health and status of ringed seals (Phoca hispida) in Alaska since 1960 by collecting information and samples from the Alaska Native subsistence harvest. This monitoring program is especially important because agencies are unable to overcome the logistical and sampling constraints necessary to estimate seal abundance in remote, ice covered waters. As such, reliable estimates of ringed seal abundance or population trend are lacking. Retrospective data analyses from this monitoring program allow us to examine how parameters that affect population size and status may vary in time and how current conditions compare with past conditions. Parameters we monitor that are indicative of population health or status include growth rate, body condition, diet, age distribution, sex ratio, age of maturation, and pregnancy rate. Since 2000, ADF&G has also conducted surveys for local knowledge and hunter preferences and analyzed tissue samples for contaminants and disease. All of these collections rely on the cooperation of coastal subsistence communities. Villages that have participated in the sampling program span the region from Hooper Bay in the Bering Sea to Kaktovik in the Beaufort Sea, including islands in the Bering Sea; an area that encompasses most of the range of ringed seals in Alaska
