Available in PDF, EPUB and Kindle. Book excerpt: This study will describe the geographic spawning distribution of radiotagged coho salmon in the Kenai River drainage for 2 years (2023 and 2024). Drift gillnets will be employed in the Kenai River to capture and tag adult coho salmon with radio transmitters. Radiotelemetry will be used to uniquely identify and track tagged coho salmon to spawning destinations. Up to 490 radio transmitters will be deployed annually between August 1 and October 31 each year. Movements of radiotagged coho salmon will be documented using a combination of fixed data-logging receiver stations and mobile tracking using boats and fixed-wing aircraft. This project will be the 2nd and 3rd year of a 3-year collaboration between the Alaska Department of Fish and Game (ADF&G) and the U.S. Fish and Wildlife Service (USFWS). The USFWS conducted the first year of the project in 2022, and ADF&G and USFWS will be collaborating on the radiotelemetry project in 2023 and 2024.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaska Department of Fish and Game (ADF&G) has monitored Chinook salmon (Oncorhynchus tshawytscha) passage in the Kenai River using side-looking sonar technology from 1987 to present at historical (1987–2012) and modern (2013–present) sites and with multiple updated sonar technologies. Starting in 2018, a similar sonar program to monitor Chinook salmon at the nearby Kasilof River was begun as well. This plan covers sonar project operations at Kenai RM 13.7 and Kasilof RM 8 for the 2023–2025 seasons with the goal of producing daily inseason net passage estimates of fish 75 cm or longer for the Kenai River and postseason net upstream passage estimates of fish 75 cm or longer for the Kasilof river.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A weir will be used on the Buskin River to count the inriver coho salmon run, with harvest estimated by the Alaska Department of Fish and Game statewide harvest survey, returned subsistence permits, and commercial fish tickets. Age and sex information will be collected from the Buskin River coho salmon run, and the composition of the run by age and sex will be estimated. In addition, coho salmon escapements to 9 other drainages on the Kodiak road system (KRS) will also be indexed. Sustainable escapement goals (SEGs) associated with the American, Olds, and Pasagshak Rivers will be monitored via postseason escapement foot surveys. A simultaneous postseason drone survey will also be conducted on the American and Olds Rivers to continue exploring establishment of drone-based SEGs. Multiple inseason surveys will be conducted by drone at each of the Olds, American, and Pasagshak river drainages to provide inseason run information to fishery managers; the inseason data will also be used to explore new ways of establishing SEGs for the Pasagshak River. Postseason escapement foot surveys will be conducted for the remaining 6 KRS rivers without SEGs (Monashka Creek, Pillar Creek, Sargent Creek, Russian Creek, Salonie Creek, and Roslyn River). The Pasagshak River coho salmon escapement will also be estimated with a temporally stratified mark–recapture study.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dual-frequency Identification Sonar (DIDSON; Belcher et al. 2002) is used annually to estimate sockeye salmon Oncorhynchus nerka passage into the Kenai River of Upper Cook Inlet (UCI), Alaska (Figure 1). Adaptive Resolution Imaging Sonar (ARIS) is used to estimate sockeye salmon passage into the Kasilof River. Both multi-beam sonar systems are manufactured by Sound Metrics Corporation with ARIS being an upgraded replacement of the DIDSON. Sonar passage estimates of sockeye salmon are used for inseason management of UCI commercial fisheries, as well as personal use fisheries in the Kenai and Kasilof rivers, to achieve established escapement goals and inriver run goals. The current sustainable escapement goal (SEG) for sockeye salmon in the Kenai River is 750,000–1,300,000 fish. The inriver goal for sockeye salmon in the Kenai River is 1,000,000–1,200,000 fish if the forecasted return estimate is 2,300,000; 1,100,000–1,400,000 fish for a forecasted return of 2,300,000–4,600,000; and 1,200,000–1,600,000 fish for a forecasted return of 4,600,000 (Marston and Frothingham In prep). The Kasilof River optimal escapement goal (OEG) is 140,000–370,000 sockeye salmon, with a biological escapement goal (BEG) of 140,000–320,000. (McKinley et al. 2020). Fish wheels are used to capture migrating salmon for 1) species apportionment; 2) to estimate age, length, and sex composition of the sockeye salmon escapement; and, 3) to collect genetic samples as needed. Historical sonar passage and escapement data for the Kenai and Kasilof rivers (Table 1) is provided in yearly Regional Information and Fishery Data Series reports as exhibited by Glick and Marston (In prep). This plan outlines how sonar sampling and logistical operations will be conducted for each of these sonar enumeration sites.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Russian River sockeye salmon escapement assessment project, which began in 1962, is one of the oldest stock assessment projects in the state of Alaska. During 2023–2026, the Russian River weir will be operated annually from early June through the first 7 to 10 days of September. All species of fish seen passing the weir through the fish chute will be enumerated daily. Sampling of sockeye salmon for age, sex, and length data will be done each Friday, and the sample size each week will be based on the previous week’s fish passage. Sockeye and Chinook salmon spawning downstream of the Russian River weir to the confluence of the Russian River and the Kenai River will be assessed by a foot survey during the fourth week of August. Multiple foot surveys will also be conducted from mid-May to 10 June to assess spawning rainbow trout.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Battle Creek coho salmon escapement project will provide daily and season-cumulative video weir counts of adult coho salmon (Oncorhynchus kisutch), a weekly and annual index of coho salmon escapement, and a catch-per-unit-effort index of the abundance of juvenile coho salmon. These estimates will be used by the Alaska Energy Authority (AEA) to fulfill a Fish and Habitat Management Implementation Plan (FHMIP) ordered by the Federal Energy Regulatory Commission (FERC) to monitor the adult and juvenile coho salmon populations in Battle Creek before and after creek diversion to assess whether a population decline has occurred (FERC 2016). Additionally, the Alaska Department of Fish and Game (ADF&G) Division of Sport Fish (SF) will use these data to better understand the size of coho salmon runs on the south side of Kachemak Bay and how these populations may be able to support sport fishing opportunities.

Book excerpt: This project is a continuation of long-term coho salmon Oncorhynchus kisutch and sockeye salmon Oncorhynchus nerka escapement monitoring within select Haines, Juneau, Sitka, and Prince of Wales area streams of Southeast Alaska. Foot or snorkel surveys will be conducted to develop annual abundance indices of adult coho salmon within 17 index streams and adult sockeye salmon in one Juneau index stream during times of peak salmon abundance during 2022, 2023, and 2024. This information is used to evaluate annual and regional trends in escapement, provide inseason information to fisheries managers, and provide information for regulatory decisions.

Download or read book Yukon River Coho Salmon Radio Telemetry written by Bonnie M. Borba and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This radiotelemetry project was initiated to gain knowledge about coho salmon (Oncorhynchus kisutch) adult migratory distribution patterns, run timing, and identify spawning areas within the Yukon River drainage. Currently, there is a deficit of baseline information for coho salmon in the Yukon River drainage. The project will collect baseline data on geographic distribution of adult spawners, inriver migration patterns, and run timing of coho salmon in the Yukon River drainage that will be critical to both habitat protection and sustainable harvest management. Geographic distribution information will be used to make nominations to the Anadromous Waters Catalog (AWC), to provide habitat protection for migration and spawning areas, as well as direct future research such as genetic baseline sampling efforts and escapement monitoring activities. This project will be the first major effort to determine coho salmon run timing, migration patterns and distribution within the Yukon River drainage. Fish will be tagged near Russian Mission. An established network of radiotelemetry stations will be used to track coho salmon enroute to spawning areas and apportion individuals into defined drainage groups. In addition, aerial surveys will be conducted to locate, and track tagged fish in otherwise unmonitored reaches of the mainstem river, tributaries, and spawning areas. Location of all detections of tagged fish will be mapped; travel time along different sections of the river will be estimated; and proportions of the total marked populations observed in different drainage groups will be determined.

Download or read book Smolt Abundance and Adult Escapement of Coho Salmon in the Taku River 2022 2024 written by Jeffrey T. Williams and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coho salmon Oncorhynchus kisutch smolt abundance and adult escapement will be estimated for the Taku stock of coho salmon originating from the Canadian portion of the Taku River, above the U.S./Canada border. This large glacial river flows into Taku Inlet about 30 km northeast of Juneau, Alaska. Multiple, independent sampling approaches will be used including coded-wire-tagging of smolt, adult harvest sampling, and an inriver adult mark–recapture experiment. A modified Petersen estimator will be used to estimate the smolt emigration during 2022–2024. A mark–recapture experiment will be used to estimate inriver runs of adult coho salmon in 2022–2024. Radio tags will be used to estimate the number of fish tagged during event 1 of the adult mark–recapture experiment that did not pass the U.S./Canada Border. Inriver harvest will be accounted for in determining escapement estimates for coho salmon annually. Scale samples of coho salmon will be used for age analysis to estimate annual age compositions. Coho salmon smolt will be systematically sampled to estimate the mean length for each species.

Starting in 2013, ADF&G began operating adaptive resolution imaging sonar or “ARIS” at a new site located at RM 13.7. The RM 8.6 site was discontinued following the 2014 season in favor of data collection at the RM 13.7 site. This plan covers RM 13.7 project operations for the 2020–2022 seasons.

Download or read book Salmon Without Rivers written by Jim Lichatowich and published by . This book was released on 1999-08 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Download or read book Dear Chairwoman written by Syvliane Grant and published by . This book was released on 2021-04-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: DEDICATED TO THE NEXT GENERATION OF WOMEN BOARD LEADERSIn 2018, California passed a senate bill (SB 826) to require publicly held companies headquartered in CA to have at least one woman on their board by 2020. In 2020, Nasdaq proposed a mandate that would require listed companies to have at least two diverse board members with one member who identifies as female. Initiatives like these are helping advance gender parity on boards in many regions, not just the U.S. In late 2020, women held 22.6% of the board seats on the Russell 3000 for the first time, a 6.5 point jump over the past 4 years.Zooming out to the global scale, the picture is similarly improving. In 2020, about 23% of board seats globally were held by women, compared to 20% in 2018. Yet...at the time of this writing, 10% of large global companies do not have a single woman on their board. And the percent of women who chair boards is dramatically smaller. Among the largest 500 public U.S. companies by revenue the share of women who chaired boards remained stagnant at 7.4%. Notably, of those women who chair boards, few of them use the term Chairwoman in their bios or LinkedIn profiles-opting for monikers Chairman, or Board Chair, or occasionally Chairperson. This book features the extraordinary voices and stories of women leaders from around the world who have trailblazed to the board room, as letters to the next generation of women in business and government. With the salutation "Dear Chairwoman," these letters are infused with the energy to inspire young women to both pursue board governance early, and to claim the 'Chairwoman' title in taking the senior-most seat in the Board Room.
