Systematics and ecology of chubs (Gila : Cyprinidae) of the Alvord Basin, Oregon and Nevada

Creator:: Williams, Jack Edward
Abstract:: Seventeen populations of Gila Baird and Girard are identified from the Alvord Basin of southeastern Oregon and northwestern Nevada. Gila in the Alvord Basin occupy a wide range of habitats, including warm springs, cool springs, creeks, reservoirs, and a thermal lake. These populations became isolated in remnant habitats when waters...

Enhanced production of Pacific dulse (Palmaria mollis) for co-culture with abalone in a land-based system

Creator:: Demetropoulos, Carl Lee
Abstract:: Palmaria mollis (Pacific dulse) is increasingly being used in land-based marine aquaculture. This work elucidates nutrient, inorganic carbon, light, salinity, and temperature requirements of P. mollis as food for abalone species. Nutrient additions every 5 to 7 days resulted in no significant difference in P. mollis growth compared with daily...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

Evaluation of shrimp and crab processing waste as a feed supplement for mink (Mustela vison)

Creator:: Watkins, Bruce Ellsworth
Abstract:: Three products derived from shrimp processing waste (Pandalus jordani) and a protein concentrate extracted from king crab waste (Paralithodes camschatica) were evaluated as feed supplements for standard dark and sapphire pelter mink (Mustela vison) replacing approximately 10 and/or 20 percent of the protein in a standard wet diet (33 percent...

Seasonal changes in distribution and abundance of salmonids and habitat availability in a coastal Oregon basin

Creator:: Sleeper, Jack David
Abstract:: Visual estimation techniques were used to quantify habitat characteristics, habitat type (pool, riffle) use and longitudinal distribution of steelhead (Oncorhynchus mykiss), cutthroat trout (0. clarki), and coho salmon (0. kisutch) in spring, summer and fall in 8.8 km of Cummins Creek, a basin in the central coast of Oregon. Fish...

Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...

Big Fishery, Big Data, and Little Crabs: Using a Genomic Approach to Examine Larval Recruitment Patterns of Dungeness Crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. In this thesis, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...
