Mean densities of derelict crab pots (DCPs), extrapolated to the number of DCPs per square kilo- 
meter of open water (A) by habitat type (marsh creek, estuarine edge, and areas adjacent to the At- 
lantic Intracoastal Waterway [ICW]) and by each of 6 waterbodies in North Carolina (Bogue, Core, 
Masonboro, and Topsail sounds and Cape Fear and Newport rivers), (B) by waterbody, and (C) by 
habitat type, and mean densities of actively fished crab pots (AFCPs) extrapolated to number of 
AFCPs per square kilometer of open water of open water (E) by habitat type and by each of the 6 
waterbodies, (F) by waterbody, and (F) by habitat type, as observed by side-scan sonar or visually, 
from April to November 2010. Note that the logarithmic scales used on the y-axes differ between 
graphs for DCP densities and graphs for AFCP densities. Levels not sharing the same letter differ 
significantly (P<0.05) in Tukey’s honestly significant difference post-hoc comparison of least square 
means of Box-Cox transformed data (panels B, C, E, and F). Error bars indicate standard errors.
