greater than or less than extraction, and when exploration creases. Three
alternative specifications of the principal model are considered, and with a
separable benefit function it is shown that a higher discount rate lends to a
lower level of cumulative exploration.

The walleye pollock (Theragra chalcogramma) is a semi-pelagic gadid
species that dominates the directed groundfish catches in the eastern Bering
Sea and Gulf of Alaska. Two approaches have been taken to evaluate the impact
of other predators on the walleye pollock population in each area; an
integrated catch at age model and major predator food habits information.
Both methods show the dominance of groundfish predation as a source of
mortality for young walleye pollock. Cannibalism is most important in the
eastern Bering Sea while predation by arrowtooth flounder is highest in the
Gulf of Alaska. In both areas, explicitly including predation mortality in
our assessment of walleye pollock stock size tends to increase our estimates
of number at age for prefishery juvenile pollock. Further insights into
predator feeding responses and factors affecting pollock recruitment into the
fishery are gained through examination of predation data.

This paper traces the evolution of snow crab fisheries science and its
impact on the management of the southern Gulf of St. Lawrence snow crab
(Chionoecetes opilio) fishery. This currently lucrative fishery (estimated
landed value of more than 100 million Canadian dollars in 1994) has
experienced the traditional rises and falls of most fisheries and the
resulting socioeconomic consequences and sometimes strained relations between
the industry and the fisheries management agency, in this case the Canada
Department of Fisheries and Oceans (DFO). Of note at this time is the
remarkable degree of cooperation that has developed between the industry and
DFO since the stock last drastically decreased (1987-1989). Since then the
stock has been recovering steadily and is also better managed. The reasons
for this are four-fold: 1) a recruitment pulse of small sized crab occurred in
1988-89; 2) substantial advances in the understanding of the complex biology
of snow crab and the development of an accurate, reliable stock assessment
methodology together have provided consistent, reliable, and credible advice
for forecasting the amount and geographic distribution of exploitable biomass
