Sammendrag
Pacific cod have been exploited in Alaska for over 100

years. Originally, the fishery was exploited in coastal waters

by U. S. fishermen. This domestic fishery declined following

World War I, ceasing by the early 1950's . In the mid-1950's

Japanese and Soviet distant water fleets began operations in

the northeastern Pacific Ocean. Pacific cod was primarily an

incidental species in the harvests of these fleets. In recent

years a U. S. cod fishery has redeveloped and is rapidly

expanding.

Coincidental to the renewed interest in a directed U. S. cod

fishery has been a strong increase in Pacific cod abundance.

Most of the increase appears to have been due to the occurrence

of an exceptionally strong 1977 year-class. Since cod is

becoming a major commercial fishery in the northeastern Pacific

Ocean it is important to develop long term estimates of yield

and accompanying management strategies. One shortcoming of such

efforts is the short time series of cod data i n Alaskan waters.

Some consequences resulting from above-average cod recruitment

in 1977 and the current high abundance level are examined.
