In earlier years, the lower Owyhee River provided excellent trout angling. In recent years, the fishery had declined to one maintained with the annual stocking of legal size hatchery trout on a put and take basis. Stream surveys completed in 1966 indicated the 16 1/2-mile section of the lower river...
The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...
A segment of the Crooked River, Crook County, Oregon, was chemically treated along with sections of Ochoco Creek, McKay Creek, and Dry River from August 13 to November 5, 1963.' A total of 860 gallons of liquid synergized rotenone (Pro-Noxfish) was used to obtain toxicities up to 2.0 ppm in...
1. A rational conservation program for such migratory fishes as the salmon must be based on a knowledge of (a) whether or not the species consists of local, self-perpetuating populations and (b) the nature and extent of the oceanic migrations.
2. The conservation of a species that is broken up...
During the 1969-70 project year emphasis was placed on spawning and rearing clams which had not been previously spawned successfully. Salinity-temperature tolerances were determined for the laboratory-reared clam larvae. Field studies comparing growth of laboratory-reared and imported Pacific and Kumamoto oysters were continued. In addition, studies comparing various methods of...

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....
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...

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...
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...
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...

It consisted of surveys to verify if Chinook salmon were using the habitats previously identified and looks for discrepancies between summer habitat inventory and fall Chinook spawners. A large portion of the...
In November, 1952, severe winter storms breached the protective Bayocean Peninsula at the mouth of Tillamook Bay. Before the month was out, the gap had widened to almost a mile.

"Oregon statutes and administrative rules, as applied to oystering, do not define the term 'production.' As a consequence, people can hold oyster claims for extended periods of time without reporting meaningful planting or production. Thus an individual can lease an unlimited amount of oyster land and continue his or her...
"Gnat Creek heir, constructed with federal funds and was completed in October 1955. Primary objectives were to quantitatively study fail chinook and silver salmon to: (1) determine the survival, timing, and size of juvenile salmonids resulting from natural spawning; (2) measure the survival of hatchery eared fingerlings and yearlings; (3)...
In July and August 1961, nine lots of 500 juvenile silver salmon each were subjected to one-, two-, three- and four-week periods of complete starvation.
