Rearing conditions and their effects on growth, food conversion, and survival of English sole (Parophrys vetulus Girard)

Creator:: Williams, Steven Frank
Abstract:: This study consisted of determining some of the conditions for culture of young English sole (Parophrys vetulus Girard) in the laboratory. Rearing of the larvae to the juvenile stage was attempted unsuccessfully; techniques used and problems encountered during culture are discussed. Growth of juveniles was studied at combinations of temperatures...

Distribution patterns of black-tailed deer (Odocoileus hemionus columbianus) in relation to environment

Creator:: Miller, Frank L.
Abstract:: Direct observation of a known number of black-tailed deer (Odocoileus hemionus columbianus), within the Cedar Creek study enclosure in the Tillamook Burn, Oregon, was carried on throughout 1964. Observations were made from three huts located outside of the enclosure on surrounding prominences. During this period, 1,410 hours of observational time...

Physiology of interrenal function in juvenile coho salmon (Oncorhynchus kisutch) and effects of hatchery rearing practices

Creator:: Patino, Reynaldo
Abstract:: Periodic determinations of plasma hormone levels suggested that changes in interrenal activity are unrelated to changes in thyroidal or gonadal activity during development (smoltification) of juvenile coho salmon (Oncorhynchus kisutch). Moreover, in an experiment where fish were reared under various conditions of crowding and water inflow rate, it appeared that...

The effects of acclimation and surface access on the resistance of fish to hypoxic stress

Creator:: Wirosoebroto-Hartadi, Retno Widaningroem
Abstract:: Rainbow trout (Salmo gairdneri) and bluegill (Lepomis macrochirus) were exposed to flows of water containing low DO concentrations produced by bubbling nitrogen through the water. Abrupt exposure of fish to critical DO concentrations (The standard dose response) and by a more gradual changing of DO levels (The "stepdown" approach) were...

Winter ecology of juvenile coho salmon (Oncorhynchus kisutch) in modified and unmodified sections of a coastal stream

Creator:: Phillips, Stephen H. (Stephen Homes), 1957-
Abstract:: Natural and gabion modified habitats containing coho salmon (Oncorhynchus kisutch) were observed and measured seasonally in East Fork Lobster Creek, a fifth order stream in western Oregon. Coho salmon usually inhabited backwater and secondary channel pools in winter. Large wood debris complexes and undercut banks were the primary sources of...

Effects of bark debris on benthic macro-fauna of Yaquina Bay, Oregon

Creator:: Walker, John David
Abstract:: Benthic samples were collected during the summer, winter and spring seasons from upper Yaquina Estuary, a region used by Georgia- Pacific Corporation for log dumping and storage. Samples came from an active log dump and storage areas as well as areas not associated with log handling activity. The samples were...

Hormonal and osmoregulatory aspects of smoltification in coho salmon, Oncorhynchus kisutch

Creator:: Specker, Jennifer Lee
Abstract:: Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were transported to tanks containing seawater and half to tanks...

Patterns of interactive segregation in three species of sculpins (Cottus) in western Oregon

Creator:: Finger, Terry Richard
Abstract:: Species interactions and their effect on the use of habitat by benthic fishes were examined in a guild composed of Cottus perplexus, C. rhotheus, and C. beldingi in the Marys River above Philomath, Oregon, and in a constant environment provided by an artificial stream. In the Marys River system, the...

The migratory pattern of audlt sockeye salmon (Oncorhynchus nerka) in Bristol Bay as related to the distribution of their home-river waters

Creator:: Straty, Richard R.
Abstract:: The individual stocks of sockeye salmon that make up the annual spawning migration to the Bristol Bay region of Western Alaska are produced in the lakes and streams of ten major river systems, which discharge into the bay over a shoreline distance of 120 miles. The hypothesis adopted in this...

Relationship between plant and butterfly community composition on upland prairies of the Willamette Valley, Oregon

Creator:: York, Melissa M.
Abstract:: Small remnants of 'natural' habitats exist today throughout much of the world. Upland prairies in the Willamette Valley, Oregon have been nearly eliminated by conversion to agriculture and other uses. As a result, very few prairies remain and at least four butterfly species that require this habitat appear to be...
