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...

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...

Redd site selection and spawning habitat use by fall chinook salmon

Creator:: Geist, David R.
Abstract:: The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained...

Utilization of dietary protein by the mussel, Mytilus edulis trossulus (Linnaeus 1758)

Creator:: Kreeger, Daniel A.
Abstract:: Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...

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...

The influence of biological characteristics on fisheries co-management : a game theory perspective

Creator:: Trisak, Jiraporn
Abstract:: Co-management is considered an alternative approach to fisheries management, however, not all co-managed fisheries have been successful. Most studies discussing the success and failure of co-management have emphasized economic and social attributes of success and failure, such as fishery rights and institutional arrangements. The effect on co-management of biological characteristics,...

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...

Development of artificial diets for delivery of water-soluble nutrients to altricial fish larvae

Creator:: Onal, Umur
Abstract:: In the present study, the potential of low-melting point lipids, namely methyl palmitate (MP) and menhaden stearine (MS), were studied for delivery of water-soluble materials to fish larvae. Addition of the solid emulsifier, sorbitan monopalmitate (SMP) resulted in higher RE compared to the liquid emulsifier sorbitan sesquioleate (SSO). Additions of...

Effects of maternal age on reproductive success in black rockfish, Sebastes melanops

Creator:: Bobko, Stephen J.
Abstract:: From 1996 through 1998 I collected mature female black rockfish off Oregon and examined ovaries and otoliths to estimate weekly, age-specific larval production. In all reproductive seasons, older black rockfish extruded larvae earlier in the season, followed by progressively younger fish. Each year, beginning in May, I collected young-of-the-year (YOY)...
