How the receiver sites identified unique types of site use for tagged Striped Bass in PIE, MA. USA. Each data point is a receiver site. Numbers inside the symbols identify the site (refer to Fig. 2C) and are the same as those used in other maps. The X axis is the average number of movements made by all Striped Bass that visited each receiver. The Y axis is the average residence time in hours of all Striped Bass that visited each receiver. Cluster 1 (solid black dots with dotted black outline) = low-use. Cluster 2 (solid dark gray square with a dashed outline) = high-use. Cluster 3 (solid light gray triangle with a solid gray outline = variable-use. Fifty tagged Striped Bass that were detected in PIE ≥ 30 days could visit each of the 26 receivers. These straightforward metrics are not exactly the same as the metrics used in the cluster analysis, but they show the same types of patterns.
