Whitefish strontium otolith readings from Benjamin et al. (2014) "Spatio-temporal variability in movemnt, age, and growth, of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry." Canadian Journal of Fisheries and Aquatic Sciences, 2014, 71(1): 131-140, 10.1139/cjfas-2013-0279
This data contains information of PIT tagged mountain whitefish detections at PIT tag interrogators in the Methow, Columbia and Entiait, rivers. This data was downloaded from the PTAGIS database at www.ptagis.org.
Connectivity of river networks and the movements among habitats can be critical for the life history of many fish species, and understanding of the patterns of movement is central to managing populations, communities, and the landscapes they use. We combined passive integrated transponder tagging over 4 years and strontium isotopes in otoliths to demonstrate that 25% of the mountain whitefish (Prosopium williamsoni) sampled moved between the Methow and Columbia rivers, Washington, USA. Seasonal migrations downstream from the Methow River to the Columbia River to overwinter occurred in autumn and upstream movements in the spring. We observed migration was common during the first year of life, with migrants being...
Data was taken at the Methow River near Pateros, WA USGS (12449950) flow station. (waterdata.usgs.gov/wa/nwis/uv?12449950). The flow data from 2009 through 2013 is used in the whitefish movement paper: "Spatio-temporal variability in movement, age, and growth of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry." Canadian Journal of Fisheries and Aquatic Sciences, 2014, 71(1): 131-140, 10.1139/cjfas-2013-0279
Strontium levels for all sites sampled in the Methow and Columbia rivers. This data was use to match whitefish stream locations to strontium levels in their otoliths. More details can be found in: Benjamin, et al (2014) Spatio-temporal variability in movemnt, age, and growth, of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry. Canadian Journal of Fisheries and Aquatic Sciences, 2014, 71(1): 131-140, 10.1139/cjfas-2013-0279
This is the temperature data used in the science product "Spatio-temporal variability in movement, age, and growth, of mountain whitefish (Prosopium williamsoni) in a river network based upon PIT tagging and otolith chemistry." Canadian Journal of Fisheries and Aquatic Sciences, 2014, 71(1): 131-140, 10.1139/cjfas-2013-0279. This study took place on the Methow River watershed. Some of the fish from this study moved into the Columbia and Entiait rivers.
