A further observation germane to the female reproductive cycle at<br />

the Pribilof Isl<strong>and</strong>s is that egg hatching in Ulga Bay occurred in both<br />

January <strong>and</strong> March (Somerton <strong>and</strong> MacIntosh 1982).<br />

Allowing for a latitudinal<br />

delay for reproductive events in the Pribilofs (e.g., Dungeness<br />

crab in California hatch eggs about 1.5 montns earlier than populations<br />

in Washington), it may be that a portion of the females hatch eggs in<br />

February or early March, others in April <strong>and</strong> May.<br />

This notion may<br />

reflect timing differences between primiparous <strong>and</strong> multiparous females.<br />

3.3 The Fishery<br />

Red king crab until recently have been the most important crab fishery<br />

of the United States in both dollars <strong>and</strong> pounds l<strong>and</strong>ed. In 1980<br />

king crab l<strong>and</strong>ings were 185 x 106 lbs <strong>and</strong> even exceeded blue crab (Callinectes<br />

sapidus) l<strong>and</strong>ings of the east coast (NOAA 1981). In 1979 to 1980<br />

the value of king crabs l<strong>and</strong>ed was about $168.7 million or 58% of total<br />

U.S. ex-vessel value of crabs (Otto, MacIntosh, Armetta <strong>and</strong> Wilson 1980;<br />

Eaton 1980; Otto 1981b; NOAA 1981) (Fig. 3.8).<br />

Of the total <strong>Alaska</strong><br />

statewide king crab l<strong>and</strong>ings in 1978-79 <strong>and</strong> 1979-80, over 75% came from<br />

catches in the southeastern Bering Sea (117 x 106 <strong>and</strong> 130 x 106 lbs,<br />

respectively; NPFMC 1980; Pacific Packers Report 1981).<br />

Red king crab<br />

commercial catches (Fig. 3.9) come largely from the middle shelf between 50<br />

<strong>and</strong> 100 m, <strong>and</strong> 50 to more than 200 km offshore of the North Aleutian Shelf<br />

(Otto 1981a, b).<br />

King crab are the largest <strong>and</strong> oldest crab caught by U. S. fisheries.<br />

Males are 50% recruited to the pot fishery at 8 years of age <strong>and</strong><br />

fully recruited by 9 years (McCaughran <strong>and</strong> Powell 1977; Reeves <strong>and</strong><br />
