6.0 DISTRIBUTION AND ABUNDANCE OF SHRIMP LARVAE IN THE
SOUTHEASTERN BERING SEA WITH EMPHASIS ON PANDALID SPECIES
Janet Armstrong
6.1 Introduction
Bering Sea shrimps, suborder Natantia, belong to at least six families
of decapod crustaceans.
In addition to the commercially important
family Pandalidae, represented by 5 species in the southeastern Bering
Sea, other families are Hippolytidae and Crangonidae (Butler 1980), and
possibly a species of the family Penaeidae (K. Coyle, U. of Alaska, IMS
- personal communication). Feder and Jewett (1980) give an extensive
list of the adult species found in this area that includes members of
the families Oplophoridae and Pasiphaeidae.
(From all samples sorted to
date only a single oplophorid larva was found and these families are
thus of no consequence in this report.)
Butler's monograph (1980) on
Pacific Coast shrimp gives ranges for many adults which were added to
Feder's list (see Appendix A).
Pandalidae are the only shrimp of direct commercial importance and
have thus received most attention in the literature.
Thorough larval
descriptions for pandalid populations of different geographic locations
are given by Berkeley (1930) for British Columbia, Pike and Williamson
(1962) for the North Sea, Kurata (1964c) for Hokkaido, Japan, and
Rothlisberg (1980) for the Pacific northwest coast (see Appendix B for
complete list of references on larval shrimp).
For identification of
Bering Sea pandalid larvae the following comprehensive species
descriptions were used:
