Seasonal distribution and environment of adult Pacific herring (Clupea harengus pallasi) near Auke Bay, Lynn Canal, southeastern Alaska

Creator:: Carlson, Harry Richard
Abstract:: The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a...

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...

Effects of light, nutrients, and grazing on periphyton communities in streams

Creator:: Gregory, Stanley Vincent
Abstract:: Relative effects of light, nutrients, and grazing on primary production were investigated in streams in the Cascade Mountains of Oregon and in laboratory streams. Relative magnitudes of primary production and associated processes were examined for one year in a stream that flowed through a clearcut and an old-growth forest in...

The length of residence of juvenile Fall Chinook salmon in Sixes River, Oregon

Creator:: Reimers, Paul E.
Abstract:: This study was designed to provide life history information about juvenile fall Chinook salmon, Oncorhynchus tshawytscha (Walbaum), in a small coastal river by 1) documenting the length of residence of the juveniles throughout the river, 2) exploring several factors possibly influencing their length of residence, and 3) assessing the relative...

Prey availability overrides cover in determining growth and abundance of stream-dwelling cutthroat trout

Creator:: Wilzbach, Margaret A.
Abstract:: The abundance and biomass of cutthroat trout (Salmo clarki) have been found to be greater in logged than in forested streams of the Oregon Cascades. Although certain prey taxa increase in abundance following logging, habitat stability generally decreases and cover structures are removed. Research was conducted to examine the manner...

Effects of sampling design, estimators, and variability on groundfish management in Oregon

Creator:: Crone, Paul R. Jr
Abstract:: Sampling error associated with estimates of species composition and age composition of commercial groundfish landings in Oregon from 1989 to 1991 is documented to evaluate the impact of variable landing data on fisheries management and monitoring programs. The statistical reliability and bias associated with two multistage sampling designs are investigated...

Life-history organization of herring (Clupea harengus pallasi) in the northeast Pacific

Creator:: Aleaziz, Farzad
Abstract:: The distribution of herring (Clupea harengus pallasi) in the Northeast Pacific extends from southern California to northern Alaska. Studies on variation in herring life-history are limited to local characteristics and recruitment populations or relatively restricted regions of the Northeast Pacific. In this study I assessed herring life-history patterns and recruitment...

Classification of Icelandic watersheds and rivers to explain life history strategies of Atlantic salmon

Creator:: Gudjonsson, Sigurdur
Abstract:: A hierarchical classification system of Iceland's watersheds and rivers is presented. The classification is based on Iceland's substrate, climate, water, biota, and human cultural influences. The geological formations of Iceland are very different in character depending on their age and formation history. Three major types of formations occur: Tertiary, Plio-Pleistocene,...
