Tide gates in the Pacific Northwest : operation, types, and environmental effects

Creator:: Giannico, Guillermo and Souder, Jon A.
Abstract:: This report is an attempt to address some critical information gaps regarding the effects of dikes and tide gates on coastal ecosystems and fisheries resources. The authors have identified the information needs during their work with landowners, community organizations, and resource management agencies and through a compilation and summary of...

An Evaluation of Collaborative Salmon Fishery Management in Prince William Sound, Alaska

Creator:: Sheridan, Thomas M.
Abstract:: Collaborative decision-making is often promoted as a means to achieve socially acceptable and enduring solutions to natural resource management issues, and one that holds promise for resolving “wicked” problems. However, success rates for implementation of collaborative recommendations are unknown. This paper explores challenges to collaborative salmon fishery management in Prince...

A steady-state model of ecological hierarchy

Creator:: Thompson, Grant Garrison
Abstract:: A generalized mathematical model of ecosystems is developed. The model begins with the general class of systems known as state-determined systems, in which the time-derivative of each state variable is a function of some subset of the set of all system state variables and .environmental parameters. A formal basis is...

Sex steroid profiles of coho salmon, Oncorhynchus Kisutch, during early development and sexual differentiation

Creator:: Feist, Grant
Abstract:: Whole body sex steroid levels of coho salmon, Oncorhynchus kisutch, were measured via radioimmunoassay during early development and sexual differentiation. Steroid profiles of testosterone (T), 11-ketotestosterone (KT) , androstenedione (A), progesterone (P4) , 17β, -hydroxy- 20β -dihydroprogesterone (DHP) , and 17β -estradiol (E2) were generated beginning with unfertilized eggs and...

A theoretical framework for economic fishery management

Creator:: Thompson, Grant Garrison
Abstract:: A theoretical framework for economic fishery management was developed. Extensive isocline analysis of a general fishery model yielded a detailed look at the possible equilibrium behavior of a system that was allowed to vary in terms of the levels of its environmental parameters, its composition, and the response functions governing...

Evaluation of data-poor and age-structure management strategies for west coast rockfish

Creator:: Arnold, Linsey M.
Abstract:: Management strategies to prevent overfishing while achieving optimum yield vary according to the available data and life history of the fished stock. I evaluated two sets of management strategies for Pacific coast rockfish: strategies to set harvest limits for data-poor stocks, and strategies intended to protect the age structure of...

Maternal effects, the environment, and age structure: A mechanistic fine-scale approach to describe a complex set of factors contributing to larval growth and survival

Creator:: Arnold, Linsey M.
Abstract:: The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...
