Managing adult hatchery summer steelhead for a recreational fishery with reduced hatchery and wild interactions

Creator:: Schemmel, Eva M.
Abstract:: Hatcheries whose purpose is to provide for a recreational fishery must minimize impacts on wild fishes. Management to reduce hatchery and wild interactions is especially important on river systems that contain Endangered Species Act (ESA) listed species. I examined adult hatchery summer steelhead, Oncorhynchus mykiss, behavior, current management and a...

Evaluation of different monitoring strategies for public health protection : harmful algal bloom surveillance at Devils Lake, Lincoln City, OR

Creator:: Hitchko, Kara L.
Abstract:: Cyanobacteria are photosynthetic bacteria capable of producing toxins, including complex cyclic peptides called microcystins. Hazardous cyanobacterial blooms are an emerging public health concern and are monitored throughout Oregon in various recreational and drinking water bodies. Oregon has been proactive and responsive to the problems associated with toxic cyanobacterial blooms, but...

Survival and behavior of juvenile steelhead trout (Oncorhynchus mykiss) in two small estuaries in Oregon

Creator:: Romer, Jeremy D.
Abstract:: A number of steelhead (Oncorhynchus mykiss) populations are at risk throughout Oregon, including five populations that are federally listed as threatened or endangered. However, little is known about behavior and survival of these fish as they transition from freshwater to seawater. We investigated whether estuarine survival varies on a temporal...

The importance of egg size for the diversity of salmonids

Creator:: Leblanc, Camille A.
Abstract:: Understanding the origin and nature of intra specific biodiversity enables us to better conserve and manage animal populations. Biological diversity is seen at different scales and for different traits such as behavior, morphology, physiology, and life history. Behavior is especially important since behavioral changes are believed to precede changes in...

Characterization of the collagen protein in smooth pink shrimp (Pandalus jordani)

Creator:: Akel, Phillip John
Abstract:: The collagen content and composition of collagens in different age classes of shrimp were determined. Their physical and chemical characteristics were investigated. The interrelationship of shrimp size and muscle collagen content to raw and cooked meat yield was established. Total collagen content for three lots of round shrimp with weights...

Proteolytic activity in Pacific shrimp (Pandalus jordani) processing waste; distribution, effects on muscle proteins, and partial characterization

Creator:: Decker, Carl David
Abstract:: Proteases present in shrimp processing waste are factors in the technology of shrimp. The distribution of proteolytic activity in shrimp parts was determined using hemoglobin and casein as substrates. The effects of various parameters upon activity of proteases in the inedible portion were determined using muscle protein as a substrate....

Acid stabilization of autolyzed fish : storage and nutritional characteristics

Creator:: Culbertson, Jeffry Dean
Abstract:: The effects of ambient temperature storage on the chemical and nutritional characteristics of phosphoric and sorbic acid-stabilized fish autolysates were determined. Variations in sample composition due to autolysis, deboning, and acidification were also evaluated. Autolysates of English sole (Parophrys vetulus), true cod (Gadus macrocephalus), Dover sole (Microstomus pacificus), and orange...

An improved procedure for holding round pink shrimp (Pandalus jordani) post-catch

Creator:: Toledo-Flores, Luis Javier
Abstract:: Chilling (2-4°C) (10 min) in a solution containing 10% condensed phosphate, 5% potassium sorbate, and 0.9% citric acid (pH 6.7) stabilized round shrimp to microbial spoilage. This treatment procedure allowed refrigerated storage of round shrimp eliminating the need for ice and the accompanying deteriorative effects of water absorption and protein...

The effect of potassium bromate on the gel-forming ability of Pacific whiting (Merluccius productus) surimi

Creator:: Aguilar, Ramon Pacheco
Abstract:: The abundance and low fat content of Pacific whiting support Its use for the production of surimi. The degradation of muscle proteins by myxosporidian secreted proteinase(s) has been associated with its soft texture. High residual activity is retained through the washing process used in the production of surimi and precludes...
