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...

Biological and mathematical modeling of dynamics of furunculosis in chinook salmon (Oncorhynchus tshawytscha) and infectious hematopoietic necrosis (IHN) in rainbow trout (Oncorhynchus mykiss)

Creator:: Ogut, Hamdi
Abstract:: A series of experiments with Aeromonas salmonicida and infectious hematopoietic necrosis virus (IHNV) were carried out to determine dynamics of the spread of infection in chinook salmon (1.2-1.98g) and rainbow trout (1.2-3.1g). It was found in experiments with A. salmonicida that fish infected by bath immersion became infectious at 4...

Growth and survival of zebrafish, Brachydanio rerio, larvae fed on two types of microparticulate diets

Creator:: Onal, Umur
Abstract:: Effects of diet and container type on growth and survival of altricial zebrafish, Brachydanio rerio, larvae were determined. Microfeast® L- 10 (MF) supported growth and survival of zebrafish larvae during the first 10-12 days. Best results were obtained with larvae fed on a combination of MF and Artemia nauplii in...

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...

Qualitative analysis of sardine and anchovy oscillations and implications for the management of sardine and anchovy fisheries in Oman

Creator:: Al-Jufaili, Saud M.
Abstract:: Sardines and anchovies are small pelagic fishes that support important commercial fisheries around the world. This project reviews the inverse cyclic behavior in the abundance of these two stocks, which is a striking feature in many regions. In addition, the project used qualitative loop analysis techniques to analyze the feasible...

Evaluating the Efficacy of Predicting Bycatch Mortality Using Reflex Impairment through an Assessment of Crab Discards

Creator:: Yochum, Noëlle
Abstract:: All animals that interact with fishing gear are not necessarily captured, and all animals that are captured are not necessarily retained. Fishing practices and gear configuration, management regulations, and markets dictate which animals ultimately are retained or discarded. The impact of a fishery and the efficacy of management regulations can...

Genetic patterns of demography and diversity in eastern North Pacific rockfishes (genus Sebastes)

Creator:: Johansson, Mattias L.
Abstract:: The 100 North Pacific rockfish species in the genus Sebastes are highly diverse. Rockfishes fertilize their eggs internally and release swimming larvae. Complex courting behaviors may allow female rockfish to be selective about their mates and may promote and maintain speciation. In this study, I applied genetic techniques to survey...

Use of extractable lipofuscin as an age biomarker to determine age structure of ghost shrimp (Neotrypaea californiensis) populations in west coast estuaries

Creator:: Cassidy, Katelyn M.
Abstract:: Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements, such as carapace length, are often used to estimate age because methods for direct ageing do not exist. However, variability in individual growth rate and molt frequency can...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

Genomics of migration : from marine distributions of salmonids to mechanisms of olfactory and magnetic cue perception for natal homing

Creator:: Bellinger, M. Renee
Abstract:: Substantial scientific investment has been directed towards understanding factors that influence distribution patterns and animals' remarkable ability for precise orientation and navigation, yet fundamental gaps in our knowledge remain. In my dissertation, I applied emerging genetic technologies to conduct a top-down and bottom-up investigation of animal movement and cue perception....
