| This report describes the results of the fourth annual study to estimate the subsistence halibut
harvest in Alaska since the National Marine Fisheries Service adopted rules governing subsistence halibut fishing in 2003. Data were collected through a voluntary mail-out survey of all holders of subsistence halibut registration certificates (SHARC). The survey response rate was 59% (8,426 surveyed of 14,206 SHARC holders.). An estimated 5,909 individuals participated in the subsistence fishery for halibut in 2006, compared to 5,621 in 2005; 5,984 in
2004; and 4,942 in 2003. The estimated harvest in 2006 was 54,089 halibut, comprising 1,125,312 pounds (+/- 2.9%) net weight. This compares to a harvest estimate of 55,875 fish comprising 1,178,222 pounds (+/-3.0%) in 2005; 52,412 fish comprising 1,193,162 pounds (+/-1.5%) in 2004; and 43,926 halibut comprising 1,041,330 pounds (+/- 3.9%) in 2003. Of the total subsistence halibut harvest in 2006, 70% was harvested with setline gear and 30% with handoperated gear. As in 2003, 2004, and 2005, the largest portion of the Alaska subsistence halibut harvest in 2006 occurred in Regulatory Area 2C (Southeast Alaska), 52%, followed by Area 3A (Southcentral Alaska), 34%. Subsistence harvests represent about 1.5% of the total halibut removals in Alaska in 2006. The harvest estimates based on the surveys for 2003, 2004, 2005,
and 2006 serve as a basis for understanding the overall harvest, annual variability in catch, and whether any increase in harvest may be associated with implementation of the new regulations. Although the 2006 harvest estimate is about the same as the 2005 and 2004 estimates and somewhat higher than the 2003 estimate, there are no certain trends in the fishery based on these
four study years. The report recommends that research be continued for at least one more year,so that at least five years of data under the current set of regulations can be evaluated. |
