title: Pasagshak River sockeye Salmon (Oncorhynchus nerka) escapement monitoring data 2022–2024

description: Since 2011, sockeye salmon (Oncorhynchus nerka) escapement through the
 Pasagshak River into Lake Rose Teed on the Kodiak Island road system has
 been estimated with a weir. A continuation of funding from the Alaska
 Sustainable Salmon Fund (AKSSF, Project #55010) allowed the Alaska
 Department of Fish and Game (ADF&G), Division of Commercial
 Fisheries to operate a PVC floating weir near the mouth of Lake Rose Teed
 during the 2022 through 2024 seasons. This data set includes the number
 and species of fish counted through the weir, and the age, sex, and length
 (ASL) information gathered from sockeye salmon captured and sampled at the
 weir.

Missing data codes: An n-dash (–) is used when there is no data because of the sample size. 5\. Specialized formats or other abbreviations used: Ages were recorded using European notation (Koo 1962), where a decimal separates the number of winters spent in fresh water (after emergence) from the number of winters spent in salt water (e.g., 2.3). The total age of the fish includes an additional year representing the time between egg deposition and emergence of fry. Length measurements were taken from mid eye to tail fork to nearest 1 mm and sex was determined from external morphological characteristics. **Sex Interpolation Dataset** 1\.
