Predation of gray whales and prolonged feeding on submerged carcasses by transient killer whales at Unimak Island
Trawls from 18 April to 5 July 1948 along the Alaska Peninsula from the western end of Unimak Island
to Ugashik Bay collected more than 19,000 female red king crab and, similar to 1941, these crab were most abundant within the Unimak-Amak-Black Hill region.

(southern fish) (Fig.
The closure extended south and east of the Pribilof Islands to the westernmost point on Unimak Island
. The halibut stock in the Bering Sea had declined to very low levels in the early 1960's, and regulations were being adopted to rehabilitate the stock (reduced fishing periods, prohibition on retention by trawls, minimum size limit, closed areas to longline halibut fishing, and closures to foreign trawl fisheries).
The Aleutian Islands archipelago ranges approximately 1800 km from Unimak Island
in the Alaska Peninsula to the Commander Islands near the Kamchatka Peninsula.
This highly active volcanic group of mountains extends from Chakachamna Lake, which is about 80 miles southwest of Anchorage, to Unimak Island
, which sits at the tip of the peninsula.
The trawl fishery has historically been concentrated on an area of the continental shelf north of Unimak Island
, where Pacific cod form dense spawning aggregations during the winter season.
The only other large assemblage of spawning pollock available to the domestic fleet was on the continental shelf north of Unimak Island
, an area used by sea lions from the eastern Aleutian Islands for foraging (letter from S.
The 2003-2004 False Pass-Unimak surveys traversed 1970 miles in Ikatan Bay and along the Pacific shore of Unimak Island
. We operated in areas of suspected high killer whale density according to information provided by local fishermen and researchers from the National Marine Mammal Laboratory (NMML) (Dahlheim, 1997) during previous transect surveys that covered broader regions.
Fishing grounds near Dutch Harbor and Unimak Island
, at the tip of the Alaska Peninsula, that were closed to 20 miles are scheduled this month to be re-opened to within 10 miles of shore because sea lion populations are increasing at an annual rate of 7 percent and 3 percent, respectively.
The major group is located just north of Unimak Island
near the end of the Alaska Peninsula.
It progressed in a southwesterly direction along the Alaska Peninsula where three main areas of flathead sole spawning were indentified: near the Kenai Peninsula, in Shelikof Strait, and between the Shumagin Islands and Unimak Island
. Flathead sole eggs are pelagic, and their depth distribution may be a function of their developmental stage.
