Body composition data for adult Sockeye Salmon returning to the Copper River, Alaska (2019-2021)

Over three years of study (2019-2021), adult sockeye salmon were lethally collected in the lower Copper River, Alaska and on spawning grounds throughout the upper watershed (n = ~10-20 individuals per collection event). The dataset consists of three separate .csv worksheets for each year data were collected. Each worksheet consists of essentially four groups of information: 1-fish identifier (ID), field collection date, and field collection location; 2-wet lab estimates of body size, sex, and reproductive parameters such as gonad weight and fecundity, identifiers for auxiliary information for otolith and scale collections, as well as estimates of percent fat based on readings from a Fat Meter - an external probe that uses a microstrip sensor that is sensitive to the water content of a sample and uses stored calibration data to convert the measured sensor value to a percentage fat/oil content; 3-dry lab information for freeze drier processing of ground somatic tissue samples for water and dry mass; and 4-dry lab information for energy density estimates of dried ground somatic tissue samples and a series of Benzoic Acid standards.
