Dates and sources of zooplankton samples searched for decapod
larvae in this study.
List of taxonomic levels of decapod crustacean larvae identified
in this study.
Number of zooplankton samples sorted between 1976-1981, and number
that were positive for both blue and red larval king crabs (see
Table 2.1 for full details). Although not officially a part of
this study, data for 1982 are included to demonstrate the high
percentage of samples positive for king crab larvae when stations
were situated nearshore. Samples with less than 500 larvae/100 m²
are summarized separately to show the proportion of positive
stations that fell into this lowest density category (see Fig.
3.11 for density categories).
A summary of larval red king crab densities in June, 1982, along
the North Aleutian Shelf. Stations were grouped into three depth
intervals along six transect lines to contrast nearshore and
alongshore distribution (see Fig. 3.14).
Mean abundance of larval red king crab along the North Aleutian
Shelf during May and June in 1976 through 1982. The region is
divided into two strata that separate distributions east and west
of 162°W latitude near Black Hills. Values are larvae/100 m² (See
Fig. 3.12 for strata boundaries).
Relative abundance and distribution of female crabs greater than
89 mm carapace in the three areas of the southeastern Bering Sea.
Stratum I and II are along the North Aleutian Shelf (see Fig.
3.16), and Remaining Bristol Bay is delineated in Fig. 3.22 for
the year 1978. Values are the mean ± 1 SD of crabs per square
mile (see the text for details on calculations).

1982 (from Eaton, 1980, 1981).

Timing of appearance of Stage I zoeae of Chionoecetes bairdi in
the southeastern Bering Sea by year and date. N1: number of
stations sampled during specified period; N2: number of stations
used in the analysis. Density of larvae is reported as number per
100 m² (range in parentheses).
Timing of appearance of Stage I zoeae of Chionoecetes opilio in
the southeastern Bering Sea by year and date. N1: number of
stations where C. opilio larvae were found; N2: mean number of
zoeae per 100 m² (range in parentheses).
Zoeal development of Chionoecetes bairdi and C. opilio showing
proportion of Stage I to total zoeae: Mean of sample observations
± one standard deviation (number of stations sampled in
parentheses).
