Figure 4 
Frequency distributions of angular directions moved for subadult red drum ( Sciaenops 
ocellatus) recovered within 60 days of tagging in coastal and estuarine waters of North 
Carolina, 1983-2007. Season and age class shown as rows and region tagged as columns. 
The four regions are the following: eastern Pamlico Sound (EPS), western Pamlico Sound 
(WPS), Neuse and Pamlico rivers (NPR), and southern North Carolina (SNC). The overall 
length of each wedge shows the relative frequency of angular observations within 20° 
bins scaled to the largest number for each plot. Each wedge is further subdivided into 
the proportion of movements in a particular direction composed of distances less than 
or equal to 20 km (white), 20.1 to 40.0 (gray), or greater than 40 km (black). Northward 
movements are straight up, and southward movements are straight down. Sample size 
is given for each diagram.
