Abstract

The market sampling program for Dover, English and petrale sole and Pacific ocean perch continued. Bottomfish landings were sampled at Astoria and Coos Bay. Dover sole research cruises were made in August 1967 and February 1968. Results on juvenile distribution are discussed. A tagging cruise for Dover sole was completed in April 1968. A short cruise was made for Pacific ocean perch. Aquaria experiments on Dover sole age and scale growth were started.
