Point observations.
<p><b>A</b>) Speckled hind and <b>B</b>) warsaw grouper encounters reported by various data sources. 25 fathom (45.7 m) bathymetric line in blue. Basemap courtesy of Esri Ocean Basemap and its partners.</p
No-take marine reserve protection per unit area.
<p>Percent of <b>A</b>) known and probable habitat and <b>B</b>) speckled hind (black) and warsaw grouper (light gray) stock per square kilometer.</p
Evaluation of existing (lower case) and proposed (italicized, all caps) no-take marine reserves for speckled hind and warsaw grouper relative to coverage of viable habitats and percent of grouper protected, as predicted by geographic distribution models.
<p>Output range for cross-validation best predictor (X-val) and best-fitting (AIC) models for speckled hind provided to characterize uncertainty. Note that geographic distribution model was unable to resolve probabilities south of 28′ latitude for warsaw grouper.</p><p><b>Note:</b> Assumes CHAPC no-anchoring provision results in 50% efficiency at eliminating bycatch mortality. Warsaw grouper percent stock estimates not generated south of 28° latitude. Oculina Bank CHAPC evaluation excludes Experimental Closed Area (ECA). Oculina Bank CHAPC Extension evaluation excludes Daytona Steeples and Daytona Ledge.</p

Point and spawning observations.
