Description
Summary:This package includes age, sex, length (ASL) data for sockeye, chinook, coho, and chum salmon from the Prince William Sound and Copper River areas. To gather age/sex/length samples, scales are taken from fish out of a representative sample caught at an ASL sampling project. These projects can be from escapement enumeration projects, commercial fishing operations, or hatchery operations. Scales from fish taken during a sampling event are placed on "scale cards," along with other information about both the sampling event (such as the date and location) and the fish itself (such as length and sex). This data package contains a number of files used in the processing of this dataset. The original data are contained with PWS_As_aged_20191028.zip. The reformatted and quality controlled data are contained in PWS_CopperRiver.csv. PSW_As_Aged_Formatting.Rmd is an RMarkdown file that does all of the processing steps, and utilizes the other supplemental files contained in this dataset for the processing.
