Abstract or Summary
  • Market sampling continues. Aging structures have been read, and all aging work is current. Age composition of Dover sole shows that stocks off Coos Bay are fully recruited 1-2 years later than stocks off the Columbia River. Age composition of English sole reveals a very strong 1961 year class. The aquarium experiment involving a study of Dover sole scale growth indicates that scales of Dover sole are sensitive indicators of stress. Stress marks associated with handling the fish when scales are taken are evident on nearly all fish. Work on the population dynamics of Dover sole is accelerating. Year-class strength calculations show that year classes of the early 1940's and middle 1950's were stronger than normal.
