Photograph measurements of broad whitefish (Coregonus nasus) body size

The dataset contains photograph measurements of broad whitefish (Coregonus nasus). Measurements (mm; with the scale set to the image) were taken using ImageJ. There are 15 measurements total; see the “Measurement Guide” file for details. Broad whitefish were harvested and photographed in the Gwich’in Settlement Area by community collaborators in 2017 & 2018, along the Peel Channel in the Mackenzie Delta and the Peel River.

Measurements were used to predict fish weight using random forest analysis as a methodology for community-based data collection. The “Data Type” column refers to the dataset fish were randomly assigned to as part of this process. “True Fish Weight (g)” and “True Fish Length (mm)” were collected in the field by community monitors.

Data collection was done as part of a research program that began in 2017 between Gwich’in community members, renewable resources organizations within the Gwich'in Settlement Area, and university scientists.
