Assemblages of groundfish caught using commercial fishing strategies off the coasts of Oregon and Washington from 1985-1987

Creator:: Rogers, Jean Beyer
Abstract:: The groundfish trawl fishery operating off the coasts of Oregon and Washington 1985-1987 caught six major assemblages of species which could be treated as units in developing mixed-species management plans. Eighty-one percent of the tows observed on commercial vessels were consistently placed in one of the assemblage designations using three...

Determination of marine migratory behavior and its relationship to selected physical traits for least cisco (Coregonus sardinella) of the western Arctic coastal plain, Alaska

Creator:: Seigle, John C.
Abstract:: With increased resource development on the western Arctic coastal plain of Alaska (especially within the oil extraction industry) it is important to understand the basic life history attributes of whitefish stocks in the region in order to ensure appropriate management. These fish are a crucial part of subsistence harvests for...

Cryo-preservation of viable fish sperm

Creator:: Graybill, James Roger
Abstract:: Fishery researchers have attempted to preserve viable fish sperm for extended periods of time. Only limited success has been achieved with storage of spermatozoa from salmonids. The principal accomplishments of this investigation during the fiscal year 1966-1967 were the development of standard methods for the collection and evaluation of fish...

Sediment characteristics and the trophic status of four Oregon lakes

Creator:: Meyerhoff, Roger Dean
Abstract:: There is evidence that recent ecological changes in lakes and their watersheds can be detected from analysis of lake sediments. This study was initiated to correlate changes in some sediment characteristics of four Oregon lakes with past cultural developments of the lakes and their watersheds. The lakes chosen for this...

The reproductive biology of the mountain cottontail rabbit in Oregon

Creator:: Powers, Roger Alan
Abstract:: The reproductive characteristics of the mountain cottontail rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269 specimens collected in central Oregon between 28 May 1968 and 28 August 1969. Male rabbits were in breeding condition between mid-February and 3 July 1969. Nearly 77% of the females bore four litters between 7...

Spatial and temporal characteristics of bottom-trawl fish assemblages of the continental shelf and upper slope of the Pacific Coast of the United States, 1977-1992

Creator:: Jay, Chadwick V.
Abstract:: Twenty-three bottom-trawl fish assemblages were identified from the relative biomass of 33 dominant species that occurred in the National Marine Fisheries Services' triennial trawl surveys over the continental shelf and upper slope off California, Oregon, and Washington from 1977 to 1992. The assemblages accounted for about 70% of the total...

The influence of social structure and molecular evolution on genetic diversity in the sperm whale (Physeter macrocephalus)

Creator:: Alexander, Alana
Abstract:: The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match. Despite a history of exploitation that removed hundreds of thousands of individuals,...

Development of a progeny marker for steelhead

Creator:: Shippentower, Gene E.
Abstract:: This study was undertaken to determine if strontium chloride could be used to create a trans-generational otolith mark in steelhead (Oncorhynchus mykiss). I completed two strontium injection trials and a survey of juvenile steelhead from various steelhead hatcheries. The two trials measured Sr:Ca ratios in otoliths in response to injections...
