in the Bering Sea but Butler (1980) gives this information for a
Canadian population (see Table 6.1).
P. tridens was caught incidentally
at only one station during the 1979 pandalid survey cruise in the southeastern
Bering Sea from the Pribilof to St. Mathew Island group and out
to the U.S. -
U.S.S.R. convention line (NUAA 1979, Cruise Results No.
79-02, R/V Sunset Bay).
The rough patch shrimp, P. stenolepis, is known to occur from
Unalaska Island to Hecata Bank, Oregon in 49-229 m depths over muddy
bottoms (Butler 1980).
Reproductive biology is poorly known for Canadian
populations (Butler 1964) and unstudied for the southeastern Bering
Sea but it is assumed to follow a typical pandalid pattern.
Needler
(1938) gives descriptions of 6 larval stages plus a first postlarva.
Larvae grow from 5 mm TL at SI to 14 mm TL at SVI in British Columbia.
The ovigerous period lasts from November until April in Canadian waters
(Butler 1980).
No commercial concentrations of this species are known
to occur in the North Pacific.
The side-stripe pandalid, Pandalopsis dispar, prefers greater
depths (>200 m according to Butler 1980) than P. borealis, and ranges
from the Pribilof Is. to Manhattan Beach, Oregon (Butler 1980).
Growth
and reproduction were studied for Canadian populations (Berkeley 1930;
Butler 1964) but no information is available for Bering Sea stocks.
Berkeley (1930) describes 5 or 6 larval stages of P. dispar growing from
10 mm TL at SI to 30 mm TL at SV. In Canadian populations males matured
at 18 months and were reproductively active for two seasons.
Transition
to females occurred by age 3 yr and death followed the hatching of a
