Sclerochronology of Walleye Dorsal Spines, 2011-2016
This data release includes both a tabular data set and a zipped file of images. The tabular data set consists of measurements of annuli widths from Walleye dorsal spine thin sections. Walleye spines were sampled non-lethally from fish that were selected for acoustic telemetry tag implantation in several interrelated investigations. The telemetry work was coordinated through the Great Lakes Acoustic Telemetry Observation System (GLATOS, https://glatos.glos.us/). Measurements were obtained from digital images of spine thin sections within the zipped file provided, and can be used to understand the age and growth characteristics of tagged Walleye. These data can be cross-referenced with biological and tagging data in the GLATOS database using an identification variable described in the attributes. A caveat is that these samples are a compilation of collections from several different independent research projects, and thus are not representative of a single walleye stock or population in the Great Lakes.
