Comparative daytime vs. nighttime core areas (50% kernel contours) and activity spaces (95% kernel contours) of fed mature female stingray number 4 at Stingray City Sandbar (SCS).

<p>Panel A) daytime; panel B) nighttime. The movement behavior displayed by stingray number 4 is representative of the behavior of the four other fed females tracked at this site.</p

Sex, size and detection duration of fed stingrays implanted with acoustic transmitters and monitored using two automated receivers deployed at Stingray City Sandbar (SCS), Grand Cayman.

Map of Grand Cayman Island showing study sites.

<p>Indicated are the locations of the supplemental feeding site Stingray City Sandbar (SCS), the two control sites South Sound and Rum Point, and a patch reef where female stingrays aggregated at night.</p

Diel detections of five mature female stingrays on bottom-fixed, automated acoustic receivers at Stingray City Sandbar (SCS).

<p>Percent values (y-axis) represent the number of days an individual stingray was detected on at least one receiver within the hourly time interval shown (x-axis). The values are expressed as a percent of the total monitored days (i.e., one or both receivers were present at SCS). Gray bars indicate typical times of ecotourism provided supplemental feeding.</p

Locations and approximate detection ranges of two bottom-fixed, acoustic receivers.

<p>The receivers were used for longer-term, automated tracking of five mature female fed southern stingrays at Stingray City Sandbar (SCS), Grand Cayman.</p

Comparative activity space sizes of fed and wild female stingrays.

<p>Activity space sizes, based on 95% kernel contours, of fed (open bars, n = 5) and wild (filled bars, n = 5) southern stingrays tracked manually at Grand Cayman during day, night and 24 hour periods. The thick horizontal lines inside the boxes represent the medians, the box edges show the upper and lower quartiles, and the whiskers represent minimum and maximum values.</p

Comparative daytime vs. nighttime core areas (50% kernel contours) and activity spaces (95% kernel contours) of wild mature female stingray number 10 at the South Sound control site.

<p>Panel A) daytime; panel B) nighttime. The movement behavior displayed stingray number 10 is representative of the behavior of the four other wild females tracked at this site.</p

Comparative overlap in daytime core activity areas of fed and wild female stingrays.

<p>Core areas are based on 50% kernel contours of five stingrays manually tracked at each site. A) the Stingray City Sandbar (SCS) supplemental feeding site, and B) the South Sound control site.</p
