Book Description
In collaboration with other entities, the Alaska Department of Fish and Game (ADF&G) attempted to conduct aerial surveys and operated ground-based weir projects to monitor Pacific salmon Oncorhynchus spp. escapement throughout the Kuskokwim Area in 2022. This report presents the results of sampling activities and escapement monitoring from all aerial surveys and weir projects operated in 2022 by ADF&G and the following partner agencies: MTNT Ltd., Kuskokwim River Inter-Tribal Fish Commission, Native Village of Napaimute (NVN), and the National Park Service (NPS). No aerial surveys were flown in 2022 due to a lack of pilot availability and poor weather. Chinook salmon O. tshawytscha escapement was successfully enumerated with weirs on 4 tributaries. Chinook salmon escapement was below average at 3 locations and above average at 1 location. Of the 12 escapement goals for Chinook salmon, 2 were assessed; 1 was met, and the other was exceeded. Chum salmon O. keta escapement was successfully enumerated with weirs on 3 tributaries. Chum salmon escapement was well below average at all locations. One escapement goal for chum salmon was assessed and was not met. Sockeye salmon O. nerka escapement was successfully enumerated using weirs on 3 tributaries. Sockeye salmon escapement was above average at 2 locations and below average at 1 location. Of the 4 escapement goals for sockeye salmon, 1 was assessed and was met. Coho salmon O. kisutch escapement was successfully enumerated with a weir on 1 tributary and was below average.

Book Description
To facilitate informed inseason management of commercial fisheries targeting Pacific salmon Oncorhynchus spp., the Alaska Department of Fish and Game (ADF&G) uses aerial and ground survey methods to monitor escapement on select index streams in Lower Cook Inlet (LCI). Surveyors make periodic counts of sockeye O. nerka, chum O. keta, and pink O. gorbuscha salmon throughout the duration of their respective runs. Fishery managers use these data daily to manipulate time and area fishery openings/closures in an effort to assure that the final escapement level for monitored stocks falls within their individual escapement goal ranges. At the end of the season, periodic aerial and ground survey counts are used to calculate a final escapement index for each stream based on the area-under-the-curve method (pink and chum salmon) or the peak survey count (sockeye salmon). This report provides operational guidelines for aerial and ground survey-based monitoring of salmon escapements in LCI.

Book Description
From June 8 through October 13, 2022, Alaska Department of Fish and Game staff operated an autonomous video counting tower (AVCT) immediately below the outlet of Red Lake within the Southern District of the Lower Cook Inlet Management Area (LCIMA). The AVCT was programmed to record high-resolution time-lapse video during daylight hours to provide information on the run-timing and magnitude of Pacific salmon (Oncorhynchus spp.) escapements into Red Lake. This project was a component of the Alaska Energy Authority’s preliminary assessment of fishery resources in the Martin River drainage, which is under consideration for future hydroelectric power development. Sockeye salmon (O. nerka), coho salmon (O. kisutch), pink salmon (O. gorbuscha), and Dolly Varden (Salvelinus malma) were captured on video migrating upstream to Red Lake in 2022. Additionally, juvenile coho salmon were collected from the lake shoreline during a spring sampling trip. The AVCT operated without interruption and documented 681 sockeye salmon with the peak daily count occurring on June 21. Peak run timing for coho salmon occurred on October 10 with a total observed escapement of 48. The AVCT documented 5 pink salmon and 53 Dolly Varden, as well as a variety of wildlife.

Book Description
The overall purpose of this project is to provide information on the run-timing and magnitude of Pacific salmon Oncorhynchus spp. escapements to Red Lake in the Southern District of the Lower Cook Inlet Management Area (LCIMA). Results will be used by Alaska Department of Fish and Game (ADF&G) and Alaska Energy Authority (AEA) staff to evaluate the extent to which salmon access and use Red Lake. This project is 1 component of the AEA’s preliminary assessment of fishery resources in the Martin River drainage, which is under consideration for future hydroelectric power development. This plan documents procedures developed for estimating salmon escapement using unmanned, or autonomous video counting towers (AVCT) that employ above-stream remote video cameras and digital time-lapse recording equipment (Otis and Dickson 2002, Otis 2020). Hard drives will be retrieved monthly, and video reviewed to enumerate daily escapement for all species identified passing the video site.

Book Description
The Alaska Department of Fish and Game (ADF & G) convened an Escapement Goal Review Team to review salmon escapement goals for the Arctic-Yukon-Kuskokwim Region in preparation for the January 2007 meeting of the Alaska Board of Fisheries. To support that effort, salmon escapement data and abundance information for the Kuskokwim Area were updated through 2005 and are represented here. From our review of Kuskokwim data we recommend biological escapement goals (BEG) for chinook and sockeye salmon, Oncorhynchus tshawytscha and O. nerka, in the Middle Fork Goodnews River; sustainable escapement goals (SEG) for chinook salmon in the George, Kwethluk, and Tuluksak Rivers; a revised SEG for Aniak River chum salmon O. keta; and that SEGs based on aerial surveys be discontinued for chinook salmon in the Kwethluk and coho salmon, O. kisutch, in the Kanektok River. This report also summarizes much of the historical salmon escapement information for the Kuskokwim Area, but in a manner that is intended to focus on the needs for assessing inter-annual trends for escapement goals. This intent is achieved through an extensive series of appendices that present historical escapement information in a standardized manner. The main body of appendices is preceded by narrative that provides context useful in interpreting the information in the appendices. In many cases data sets in the appendices are truncated in order to address standardization needs. As such, investigators seeking more complete information should consult master escapement files maintained by ADF & G, original aerial survey forms, and detailed project reports.
