DEPTH IN METERS 



Figure 3. — Index of abundance (geometric mean) of Raja eglanteria captured in Chesapeake Bight during each 

 cruise within each depth stratum. Data collected north and south of lat. 37°N were analyzed separately. The 

 fraction over each bar is the ratio of the number of stations at which the species was captured to the total number 

 of stations in each stratum. Whole numbers represent the number of stations in the strata in which no specimens 

 were captured.
