Smalltooth sawfish (Pristis pectinata) density in the Caloosahatchee River in Spring/Summer 2021. (A) Predicted density of age-0 and age-1 individuals for average environmental conditions from March through August 2021, based on interpolation of daily-averaged sonde data by empirical Bayesian kriging; and (B) Point data from U.S. Sawfish Recovery Database (2015–2023; all life history stages), targeted sampling (2004–2022; age-0 and age-1 only), and random gillnet sampling (2010–2022). Red polygons denote “high-use areas” or “hotspots” previously identified for small juveniles by [19] and [40]. Basemap used with permission from ESRI World Imagery and its partners.
