The National Oceanic and Atmospheric Administration awarded a $1.19 million project grant to the Alaska Department of Fish & Game through the Pacific Salmon Treaty Program (CFDA #11.438) to support assessment and data collection activities for Chinook salmon stocks in Alaska from July 1, 2022 to June 30, 2023. Specifically, the grant will fund projects to estimate abundance, age/sex composition, outmigration numbers of smolt, and future marine harvest of Chinook salmon in the Chilkat River drainage. It will also support the purchase of ruggedized tablet computers for commercial and field data collection on Chinook salmon harvests. As the sub-awardee, the State of Alaska will assist in fulfilling responsibilities under the Pacific Salmon Treaty to support salmon restoration efforts.

Pacific salmon treaty FY22 program in support of the below projects: the objectives for assessment of the chilkat river stock of chinook salmon are: 1. To estimate the inriver abundance of large (=AGE1.3) chinook salmon in the chilkat river drainage, so that the estimate is within 25% of the true value 90% of the time. 2. To estimate the age and SEX proportions of the inriver run of large chinook salmon in the chilkat river, so that the estimates are within 10% of the true values 90% of the time. 3. To estimate the number of chinook salmon smolt emigrating from the chilkat river in spring 2023, so that the estimate is within 40% of the true value 90% of the time. 4. To estimate the marine harvest of chinook salmon from the 2021 brood year in 2024-2028 such that the estimate is within 30% of the true value 90% of the time. Project 2 objectives: 1. To purchase three PC-based ruggedized tablet computers for commercial and field project data collection from chinook salmon HAR
