This report summarizes program progress in FY 1974. Activities were directed entirely at completing the third of four phases of work started in 1971. The survey conducted in September 1973 was the second run over the continental shelf off the northern Oregon coast. Objectives of the survey were to obtain...
Market sampling continues. Most samples have been aged. Several cruises were made during fiscal year 1969-70. The deep water survey for Dover sole yielded questionable results. Neither spawning concentrations nor concentrations of males were located. Calculations of year class strength for English sole showed that the 1961 year class was...
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...
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...
The market sampling program for Dover, English, and petrale sole, and Pacific Ocean perch continued. Market conditions severely limited landings during the last quarter. A Dover sole cruise was completed in May. Data from the July 1966 Dover sole cruise plus data from two shrimp cruises (October-November 1966 and March-April...
This annual report, which summarizes program progress in FY 1971 is submitted as an interim statement pending completion of the final report of PL 88-309 studies on Dover sole. That report which deals with yield estimates of Dover sole in PMFC area 3A was delayed pending completion of yield calculations....
This report summarizes program progress in FY 1973. Activities were directed entirely at completing the second phase of the work started in 1971, i.e., to complete the resource survey of the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...
This report summarizes project progress in FY 1974. Activities were directed entirely at completing the fourth and final phase of work started in 1971, i.e., to survey groundfish resources on the continental shelf off Oregon between the Columbia River and Cape Blanco. Objectives of the survey were to obtain estimates...
This report summarizes program progress in FY 1972. Activities were directed almost entirely toward the groundfish survey of the continental shelf off Oregon between the Columbia River and Cape Blanco. Since the area was too large to be surveyed in one cruise, it will be surveyed over a two year...
Dover sole (Microstomus pacificus) has been subject to intensive fishing In waters off northern Oregon-southern Washington (specifically PMFC Area 20) since 1941 (Harry, 1956). This species has always been an Important contributor to the trawl fishery and has been the most valuable species of groundflsh landed In Oregon since 1966....
