Figure 5 
Summer distributions of primiparous female snow crabs (Chionoecetes opilio) during (A) 2010, (C) 2011, and (E) 
2012 and of multiparous females during (B) 2010, (D) 2011, and (F) 2012, determined from data collected from the 
National Marine Fisheries Service summer bottom trawl surveys of the eastern Bering Sea. Bar heights indicate 
the catch per unit of effort (number of females per square kilometer). Ellipses indicate the tag release locations 
of morphometrically mature males. The black line indicates the 100-m bottom-depth contour, designating the ap- 
proximate border between the middle and outer shelves.
