Salmon age, sex, and length, Prince William Sound and Copper River, 1960-2016

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). As Aged.zip contains several fixed-width files, AscIIHeaderinfo.jpg gives more detail on the positions of information within the fixed-width format, and filanameinfo.jpg describes the file format and codes contained within the filenames. The file PWS_AsAged_Formatting.Rmd (and its output, PWS_AsAged_Formatting.html) details the processing steps taken to produce the reformatted data file, PWS_CopperRiver.csv, from the fixed-width files. The excel files aspws.xls and CBRStrmCodes.xls include stream level location information for Prince William Sound and Copper River, and the file PWS_location_lookup.csv is used to add location information to the data file.
