Assessment of the 1993 return of steelhead to the Karluk River, Alaska

Author: Begich, R. N.
Date: 1995
Organization: ADF&G Division of Sport Fish
Species (Common Name): Steelhead
Region: Alaska
Abstract Snippet
Beginning August 15, 1993, commercial set gill net and purse seine catches from selected waters along the southwest side of Kodiak Island were sampled for the incidental harvest of steelhead trout Oncorhynchus mykiss. The total estimated incidental commercial catch of steelhead from waters included in the Karluk study area, between August 15 and August 31, was 58 fish. A total of 21 steelhead were harvested for personal use and 17 were released from the set gill net fishery. Set gill net

Stock assessment of the return of early-run chinook salmon to the Kenai River, 1994

Author: Hammarstrom, S. L.
Date: 1995
Organization: ADF&G Division of Sport Fish
Species (Common Name): Chinook Salmon
Region: Alaska
Abstract Snippet
The total in river return of early-run chinook salmon Oncorhynchus tshawytscha as estimated through hydroacoustic techniques was 18,403. Angler effort and harvest as estimated by a creel survey during the early (May and June) chinook salmon run were 173,842 angler hours and 5,634 chinook salmon, respectively, approximately 7% greater than the 1974-1993 mean. Release mortality was estimated at 128 fish. Spawning escapement, estimated by subtracting total fishing mortality from total inriver

Stock assessment of the return of late-run chinook salmon to the Kenai River, 1994

Author: Hammarstrom, S. L.
Date: 1995
Organization: ADF&G Division of Sport Fish
Species (Common Name): Chinook Salmon
Region: Alaska
Abstract Snippet
The estimated total return of late-run chinook salmon Oncorhynchus tshawytscha to the Kenai River in 1994 was 71,899. This estimate includes fish harvested in the recreational marine fishery near Deep Creek, which was estimated by creel survey for the first time since 1986. The total harvest in the marine recreational fishery, the marine commercial gillnet fisheries (drift and set), the marine subsistence set gillnet fishery, the inriver subsistence dip net fishery, and Kenaitze Indian

Stock assessment and biological characteristics of burbot in Parker, Fielding Lake during 1994

Author: Parker, J. F.
Date: 1995
Organization: ADF&G Division of Sport Fish
Species (Common Name): Burbot
Region: Alaska
Abstract Snippet
Abundance and index of abundance were estimated for a population of burbot Lota lota in Fielding Lake. Burbot were captured in baited hoop traps. Traps were set in a systematic pattern across Fielding Lake. Sampling occurred during June of 1994. Estimated mean CPUE per 48-hour set of fully (450 millimeters total length and longer) and partially (300 to 449 millimeters total length) recruited burbot in Fielding Lake was 0.52 (SE = 0.08) and 0.54 (SE = 0.07), respectively. Abundance of fully

Southeast Alaska 2018 herring stock assessment surveys. (2

Author: Hebert, K.
Date: 2019
Organization: ADF&G Division of Commercial Fisheries
Species (Common Name): Herring
Region: Alaska
Abstract Snippet
Pacific herring, Clupea pallasii, are important prey for many marine species found in Southeast Alaska and are also harvested in fisheries for commercial bait, commercial sac roe, commercial spawn-on-kelp, subsistence spawn-on-branches, subsistence spawn-on-kelp, personal use, and research/cost-recovery purposes. The Southeast Alaska Herring Management plan (5 AAC 27.190(3)) requires the Alaska Department of Fish and Game to assess the abundance of mature herring for each stock before allowing

Age, sex, and length composition of Chinook salmon harvested in the 2016 and 2017 Lower Kuskokwim

Author: Liller, Z. W., K. E. Froning, N. J. Smith J. Esquible.
Date: 2019
Organization: ADF&G Division of Commercial Fisheries
Species (Common Name): Chinook Salmon
Region: Alaska
Abstract Snippet
The Kuskokwim River Chinook salmon Oncorhynchus tshawytscha subsistence fishery has been one of the largest in Alaska and collection of age, sex, and length (ASL) data from the subsistence harvest has been an important component of the Kuskokwim Area stock biology program. The Alaska Department of Fish and Game, Division of Commercial Fisheries, the Orutsararmiut Native Council, and the Bering Sea Fishermen?s Association partnered to recruit local residents to collect ASL data from subsistence

Subsistence salmon harvests in the Kuskokwim Area, 2016

Author: Lipka, C. G., T. Hamazaki, M. Horne-Brine J. Esquible.
Date: 2019
Organization: ADF&G Division of Commercial Fisheries
Species (Common Name): Salmon
Region: Alaska
Abstract Snippet
The Alaska Department of Fish and Game (ADF&G) in partnership with Orutsararmiut Native Council (ONC) in Bethel conducted a voluntary survey program to estimate subsistence salmon harvest for the Kuskokwim Management Area in 2016. Harvest information was collected through postseason household interviews and harvest calendars. Simple random sampling and stratified random sampling techniques were used, based on community size and user group designations, to select households to be interviewed

Sonar estimation of summer chum and pink salmon in the Anvik River, Alaska, 2018

Author: Broderson, N. B.
Date: 2019
Organization: ADF&G Division of Commercial Fisheries
Species (Common Name): Chum Salmon, Pink Salmon
Region: Alaska
Abstract Snippet
Dual-frequency identification sonar (DIDSON) was used to estimate adult summer chum salmon Oncorhynchus keta and pink salmon O. gorbuscha passage in the Anvik River from June 15 to July 26, 2018. Apportionment to species was determined using data collected from tower counts. A total of 305,098 (SE 5,926) summer chum and 1,122,346 (SE 7,588) pink salmon were estimated to have passed the sonar site. A beach seine sample fishery was conducted to collect age, sex, and length information. Both sonar

Author: Yanusz, R. J., P. M. Cleary, J. Campbell, G. Horner-Neufeld, D. Reed N. A. DeCovich.
Date: 2018
Organization: ADF&G Division of Sport Fish
Species (Common Name): Chinook Salmon, Coho Salmon
Region: Alaska
Abstract Snippet
Between 2012 and 2014, information was collected on the distributions and abundances of adult Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon as part of the Susitna-Watana Hydro studies conducted by the Alaska Department of Fish and Game in partnership with LGL Alaska Research Associates Inc. and the Alaska Energy Authority. Spawning distributions were assessed using radiotelemetry for Chinook salmon in the mainstem Susitna River in 2012?2014 and in the Yentna River in 2013

Anchor River Chinook salmon escapement, 2011

Author: Kerkvliet, C. M. M. D. Booz.
Date: 2018
Organization: ADF&G Division of Sport Fish
Species (Common Name): Chinook Salmon
Region: Alaska
Abstract Snippet
The 2011 Anchor River Chinook salmon (Oncorhynchus tshawytscha) escapement was censused using dual-frequency identification sonar (DIDSON) during high spring flows and by a resistance board weir when flows subsided. The Chinook salmon escapement, an estimated 3,545 fish, fell below the sustainable escapement goal (SEG) range of 3,800?10,000 Chinook salmon and was the second lowest on record. The midpoint of the Chinook salmon run was 16 June. The Chinook salmon daily escapement counts were
