Figure 5.5 Mean density <strong>and</strong> one st<strong>and</strong>ard deviation of Erimacrus isenbeckii larvae in the<br />

southeastern Bering Sea for all years, 1976-1981, combined. The range of densities<br />

from which these means were calculated are listed above each corresponding<br />

bar; while the number of samples used to calculate each mean, n, are listed on<br />

the lower axis. Stations at which no larvae were found were not used in calculating<br />

the mean density of Erimacrus isenbeckii larvae within each stratum (see Fig. 2.8).
