| Abstract: | This report amends ROP.SF.2A.2019.11. The Crooked Creek Chinook Salmon Enhancement Project is designed to monitor both naturally- and hatchery-produced Chinook salmon escapements as well as collect brood stock and conduct egg takes to provide additional sport fishing opportunities within the Kasilof River and other terminal fisheries throughout Southcentral Alaska. This project imprints Chinook salmon smolt for 7 to 10 days at the beginning of June. Additionally, age, sex, and length samples will be collected from returning naturally- and hatchery-produced Chinook salmon. Currently, Crooked Creek has a sustainable escapement goal (SEG) of 700–1,400 naturally-produced ocean-age-2+ Chinook salmon. The overall goal of this research program is to reconstruct naturally- and hatchery-produced returns of Chinook salmon to Crooked Creek such that a biological escapement goal (BEG) can be established. |
