INTRODUCTION This document is intended to provide commercial herring fishers and buyers with information and guidelines the Alaska Department of Fish and Game (ADF&G) will use to manage the Alaska Peninsula and Aleutian Islands Management Areas commercial sac roe herring Gheries. The Alaska Peninsula and Aleutian Islands Management Areas (Figures 1-8) are described as Management Area "M" and are divided into three subareas: (1) the North Peninsula, consisting of Bering Sea waters extending west from Cape Menshikof to Cape Sarichef; (2) the South Peninsula, consisting of Pacific Ocean coastal waters extending west of Kupreanof Point to 163O30' W.long. (the south side of Unimak Island near Cape Lazaref); and (3) the Aleutian Islands, consisting of Bering Sea waters extending west of Unimak Pass and Paciiic Ocean waters extending west of 163O30' W.long. (the south side of Unimak Island near Cape Lazaref) to the International Date Line. The North Peninsula fishery has occurred annually since 1982 while the South Peninsula sac roe herring fishery has occurred annually since 1979 (except in 1983 when the Alaska Board of Fisheries allocated the entire sac roe catch to the food and bait fishery; Table 1; McCullough and Campbell 1995). The Aleutian Islands Area has had no sac roe deliveries. All fisheries continue to be open-to- entry. The sac roe fisheries target on individual herring stocks immediately prior to spawning to ensure the greatest roe development and maximum roe recovery. The desired product during the sac roe f~heries is pre-spawn herring having a roe recovery of about 1095, roe recovery standards are determined by - -. - industry. The 1991-95 North Peninsula sac roe fishery averaged 1,249 tons. The 1991-95 South Peninsula sac roe fishery averaged 101.1 tons. By regulation, both purse seine and gillnet gear are allowed to f~shin any open area. Gillnet gear has not been used with much success, by regulation both gears have similar fishing times during each fishing period. The commercial fisheries are intended to occur with minimal waste of the resource and within conservation limits as determined by ADF&G. ADF&G does not manage the Alaska Peninsula and Aleutian Islands Management Areas commercial sac roe herring harvest to enhance the value of the landed product because adequate inseason information and staff are not available (ADF&G 1994; 5 AAC 27.059). ADF&G will manage the fisheries per the statewide general herring guideline harvest policy which provides for harvests not to exceed 20% of the available spawning biomass (ADF&G 1994; 5 AAC 27.060). Herring quality will be determined by the pennit holder and the buyer. Roe recovery will not be a criteria for emergency openings or closures except in cases where excessive wastage is expected to be a factor. Permit holders are encouraged to check with their markets prior to fishing to deterxnjne acceptable minimum size, weight, and roe percentages. All herring harvested during the sac roe season which are sold as bait or discarded due to quality problems will be included as part of the total sac roe herring harvest. Management units with guideline harvest levels (Table 2) are areas with individual stocks and have a history of sac roe harvests. Management units lacking historic harvests and biomass estimates are open for exploration and may potentially support sac roe iisheries. Additional management units are open for exploration where f~heriesoccur outside of bays and lagoons and are not perceived to have habitat suitable for herring spawning. Due to the lack of data fiom exploratory areas, annual harvest levels may fluctuate considerably until more information about the stock status is obtained. Inseason emergency order closures for each area will occur as the guideline harvest levels for each unit are achieved. Closures may be necessary prior to attaining a guideline harvest level if the fishery performance or aerial surveys indicate that a stock biomass is less than anticipated. Harvests in excess of their guideline harvest level will occur if the assessed available spawning biomass warrants continued catches. Closures will be used to ensure that excessive harvests in exploratory areas do not occur. The North Peninsula sac roe guideline harvest level has been reduced to account for North Peninsula herring that are probably harvested during the Aleutian Islands (Dutch Harbor) food and bait fishery (Funk 1991). Non-Togiak herring stocks comprise about 22% of the Aleutian Islands herring catch; due to the July 16 opening date of the food and bait fishery, North Peninsula herring stocks probably comprise the majority of the non-Togiak herring component. The 1996 Aleutian Islands food and bait harvest allocation is 1,793 tons (KIA. Rowell, Alaska Department of Fish and Game, Anchorage, personal communication 1995). To insure that North Peninsula herring stocks are not harvested beyond a 20% exploitation rate for both the sac roe and foodhait fisheries combined, a sac roe exploitation rate of 16% of the spawning biomass will be the management goal. Inseason emergency orders will be broadcast on the single side band radio on 4125 and 3230 Khz and on the VHF radio on channels 6 and 72, or other channels if arrangements are made with the local resentative of ADF&G. Current annou nts will be available 24-ho ord-a-phone at 383-2334.

INVESTIGATIONS OF ^ALASKAN VOLCANOES GEOLOGICAL SURVEY BULLETIN 1028-L Prepared in cooperation with the Office, Chief of Engineers, U.S. Army UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1959 UNITED STATES DEPARTMENT OF THE INTERIOR FRED A. SEATON, Secretary GEOLOGICAL SURVEY Thomas B. Nolan, Director For sale by the Superintendent of Documents, U.S. Government Printing Office Washington 25, D.C. PEEFACE In October 1945 the War Department (now Department of the Army) requested the Geological Survey to undertake a program of volcano investigations in the Aleutian Islands-Alaska Peninsula area. Field studies under general direction of G. D. Robinson, were begun as soon as weather permitted in the spring of 1946. The results of the first year's field, laboratory, and library work were assembled as two administrative reports. Part of the data was published in 1950 in Geological Survey Bulletin 974-B, "Volcanic Activity in the Aleutian Arc", by Robert R. Coats. The rest of the data has been included in Bulletin 1028. The geologic investigations covered by this report were recon­ naissance. The factual information presented is believed to be accu­ rate, but many of the tentative interpretations and conclusions will be modified as the investigations continue and knowledge grows. The investigations of 1946 were supported almost entirely by the Military Intelligence Division of the Office, Chief of Engineers, U.S. Army. The Geological Survey is indebted to that Office for its early recognition of the value of geologic studies in the Aleutian region, which made this report possible, and for its continuing support.

  • Geographic Distribution, Depth Range, and Description of Atka Mackerel Pleurogrammus Monopterygius Nesting Habitat in Alaska
    Alaska Fishery Research Bulletin 12(2):165 –186. 2007 Copyright © 2007 by the Alaska Department of Fish and Game Geographic Distribution, Depth Range, and Description of Atka Mackerel Pleurogrammus monopterygius Nesting Habitat in Alaska Robert R. Lauth, Scott W. McEntire, and Harold H. Zenger Jr. ABSTR A CT : Understanding the spatial and bathymetric extent of the reproductive habitat of Atka mackerel Pleuro- grammus monopterygius is basic and fundamental information for managing and conserving the species. From 1998 to 2004, scuba diving and in situ and towed underwater cameras were used to document reproductive behavior of Atka mackerel and to map the geographic and depth ranges of their spawning and nesting habitat in Alaska. This study extended the geographic range of nesting sites from the Kamchatka Peninsula to the Gulf of Alaska, and extended the lower depth limit from 32 to 144 m. Male Atka mackerel guarding egg masses were observed during October—indicating that the duration of the nesting period in Alaska is more protracted than in the western Pacific. Results from this study also suggest that nearshore nesting sites constitute only a fraction of the nesting habitat and that there is no concerted nearshore spawning migration for Atka mackerel in Alaska. Nesting sites were wide- spread across the continental shelf and found over a much broader depth range than in the western Pacific. Nesting habitat was invariably associated with rocky substrates and water currents; however, smaller-scale geomorphic and oceanographic features as well as physical properties of the rocky substrate were variable between different island groups and nesting sites.

INTRODUCTION: THE ALEUTIAN ENVIRONMENT I There are many problems inherent in attempting to fully assess the I cultural resources of an area such as that encompassed in the boundaries of the Aleut Corporation. While there are many things which bind the I area together into a unified whole, there are also many differences which must be taken into consideration. Yet both the differences and I the unifying aspects are, in large part, caused by the geographic location I and environmental effects of the region upon its inhabitants. The Aleut Corporation consists of the Aleutian Islands themselves--a I chain of volcanic mountaintops reaching out over 1,100 miles across the northern Pacific; a 200-mile portion of the lower Alaska Peninsula and the island groups (Shumagin, Popov, and Sanak) off the Peninsula's I southern coast; and the Pribilof Islands, located in the Bering Sea 300 miles west of the Alaskan mainland and 200 miles north of the Aleutians.

ALEUTIAN WORLD WAR II STORIES INTRODUCTION Beginning in 2006, the Aleutian World War II National Historic Area has produced calendars with each month focused on an illustrated history related to the program’s interpretive themes. The calendars have had broad nationwide appeal and were provided to veterans’ groups and homes, historical societies, schools, libraries and members of the public with a personal connection or interest in World War II in the Aleutians. Each year the calendars interwove and built upon the two main themes of the national historic area: the Aleutian military campaign and the Unanga{ (Aleut) experience of World War II. The calendar stories also refected the program’s focus on the natural environment as well as historic preservation, both in reference to Unanga{ culture and history and to the military campaign. The calendars also explored previously unknown sides of the World War II Aleutian experience, including primary research on the personal histories of soldiers and civilians in the Aleutian Islands.
