Decision matrix based on average policy ranks within each 
metric used to evaluate harvest control rules (HRO, HR10, 
HR15, HR15U, and HR30) for golden king crab (Lithodes 
aequispinus) in the Aleutian Islands, when a linear rela- 
tionship between catch per unit of effort and selected 
abundance is assumed in the operating model. Values are 
based on the last 10 years of the 30-year projection period, 
which begins with 2018. The stock is projected from 2 ini- 
tial levels of abundance, measured in mature male bio- 
mass (MMB): a healthy state (i.e., MMBoo)./MMB3,=1.55, 
where MMBoo13 is MMB in 2018 and MMB,, is 35% of 
the unfished level of MMB) and an overfished state (i.e., 
MMB 499/MMB,;=0.50). Values are average ranks within 
each metric, with ranks of the average metric ranks given 
in parentheses. The ranks of the catch metric correspond 
only to the long-term averages of retained catch; therefore, 
no average ranks were computed. For details about the 
harvest control rules, see Table 1.
