Partial assessment of the skate stock complex in the Bering Sea and Aleutian Islands
In Stock assessment and fishery evaluation report for the groundfish resources of the Bering Sea/Aleutian Islands regions, p.
Halibut fishing regions are as follows: Southeast (2C), the Gulf of Alaska (3A/B), Bering Sea and Aleutian Islands
(4 A/B/C/D and the Community Development Quota).
In Alaska, 2 unique neighboring geographical regions are present, the eastern Bering Sea and Aleutian Islands
. The eastern Bering Sea continental shelf consists of 3 main oceanographic domains associated with bottom depths (inner, 0-50 m; middle, 50-100 m; and outer, 100-200 m); distinct regions exhibiting unique patterns of oceanic and biological processes (Bakkala 1993; Schumacher and Stabeno 1998; Stabeno and others 2001).
Commercial fishing activity in the Bering Sea and Aleutian Islands
is conducted primarily on large vessels, which are required to have 100% observer coverage, and therefore observer data should provide a good representation of skate bycatch in those regions.
In 1992, 18.5 km (10 n.mi.) radius trawl closures were also implemented around all rookeries in the Bering Sea and Aleutian Islands
Hypsagonus quadricornis is known from the northeastern Chukchi Sea (Mecklenburg and others 2011), Bering Sea and Aleutian Islands
to Puget Sound, Washington, in the east, and from the Commander Islands, the Sea of Okhotsk, and the northern Sea of Japan in the west.

region in 1987, p.
Similarly, the spawning biomass was estimated to be at its highest level: ever recorded in the Bering Sea and Aleutian Islands
, at more than 8.24x [10.sup.5] t (Wilderbuer and Nichol, 2006).
A FMP for Bering Sea and Aleutian Islands
(BSAI) groundfish was formally implemented in 1982.
Four general regions were identified: 1) western Pacific Ocean, for material taken in Japanese and Russian waters; 2) Bering Sea and Aleutian Islands
, for material from the eastern Bering Sea and Aleutian Islands
to Unimak Pass; 3) Gulf of Alaska, from Unimak Pass to the Alaska-British Columbia border; and 4) the Lower West Coast, from Canada, Washington, Oregon, and California.
The ABC'S are initially determined by stock assessment scientists and reviewed by separate Bering Sea and Aleutian Islands
(BSAI) region and Gulf of Alaska (GOA) Plan Teams.
