There some of them go to Kodiak Island. The most notable concentrations
of fin whales in the Gulf of Alaska are observed west of the
Alexander Archipelago, and later in the southerrunost part of the
Gulf of Alaslca, at approximately 52° N, 14'7° W, and from the Shumagin 171
islands to Kodiak Island and in the northernmost part of the Gulf.
The ::Ia.t•raii--Aleutian herd spend the winter in the waters
around the Hawaiian Islands; in summer, possibly, they feed in the
waters adjacent to the northern Kurile Islands, eastern Xrmchatka,
and the Komandorskie and Aleutian Islands, also in the Bering and
Chulï.chi Seas and in the western part of the Gulf of Alaska.

The nunibers of fin whales on the Pacific side of the Aleutian
chain are very sinall, and diminish to the west from the Fox Islands
along the 50th parallel. Only in the area about 46° N, 175° E are
small concentrations of the animals sometimes observed.
In summer and autuinn (from June to November) fin whales are
found in the western part of the Bering Sea from Cape Navarin south
to Ya.ra.ginslcii Isla.nd. Sometimes large groups of them are seern
northwest of Bering Island. In the Gulf of Anadyr they usually conceni,rate
in the central and western parts.
Fin whales occur less often in ti,e northern part of the
Bering Sea. Those pas::ing into the Chukchi Sea, concentrate mainly
in the Cape Serdtse---K-amen' region. According to some reports, they

In the open sea iiu to 58 0 AI fin whales feed mainly on crust.-
aceans. _^ett-reen the IComandorskie Islands and the Blizhnie Islands
Euphausiacea ( Thyûa.noessa j and Copenoda ( C^ lanus) constitute up to
60;;: of the stor.lach contents. 1^1orth of the 58th parallel fishes
(capelin and herring) predominate in the diet, 1_ sanoessa occurring
less often. Along the Alaska Peninsula the whales feed on walleye
pollock and various crustaceans, and in the Gulf of Alaska they
feed mainly on crustaceans.
During the fattening period._ sezually-immature fin whales
usually stay in the northern waters of the.Aleutian Islands, and to
a lesser extent in the western -^.art of the Bering Sea. - Solitary
