Resource Abstract:
- description: Polar bear harvests in Alaska coastal villages from November 1980 to April 1982. Hunters from 13 villages killed
polar bears during this period. The documented minimum polar bear harvest for 1980/81 and 1981/82 hunting seasons were 106
and 90, respectively. A minimum of 21 bears were harvested from January 1 to July 30, 1980 (ADF&G records) and have been
included in the pooled sample of 217 killed bears. Of this total, 134 (61.8%) were bears for which complete sex and age information
was obtained; 52 (23.9%) were bears for which adequate sex and/or age class information was obtained; and 31 (14.3%) were
bears known to have been killed for which sex and age information was unknown. The sample of 134 known sex and age bears consisted
of 27 percent litter members (cubs, yearlings, or 2-year olds), 31 percent females greater than 3 years of age, and 42 percent
males greater than 3 years of age. The sex ratio was 81 (60.4%) males to 53 (39.6%) females. The sex ratio of bears captured
from 1967-76 in a tagging study (Lentfer, 1977) was significantly different. The mean age of males and females was 7.3! 4.8
years. Male mean age was 5.8 3.9 years and female was 9.0 5.4 years. A significant inverse relationship was determined for
harvested female cubs less than 3 years, female subadults, 4-5 years, and females age 6-10. A significant positive relationship
was determined for harvested females 10 years or older, subadult males, and adult males 6 years or older. From January 1980
to April 1982 an average annual removal of 38 females occurred. This figure excluded 31 unknown sex and age bears. If the
percentage of adult females of known sex and age bears is applied to the 31 excluded bears then the average annual female
removal was 44 bears. Polar bears were harvested during each month of the year except September. Of 197 bears sampled, 123
(62.4%) were harvested during November, December, and January. Forty-five bears (22.8%) were harvested in October and November,
primarily in the North Slope villages. Recent harvest chronology differs markedly from that of the sports hunting era when
most bears were taken from February through April. Of the 124 hunters who killed 217 polar bear during 1980-82, 37 (29.8%)
killed more than one bear; of these, 27 (73.8%) killed more than 2 bears. Snowmachines (89.5%) were the most common hunting
transportation form used, small boats (6.8%) ranked second and other means accounted for the remainder of the harvest.; abstract:
