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...

Selected life history aspects of American shad (Alosa sapidissima) and predation on young-of-the-year shad in Lake Umatilla of the Columbia River

Creator:

Stainbrook, Cris Eric

Abstract:

Selected life history aspects of American shad, Alosa sapidissima, collected in Lake Umatilla of the Columbia River during 1980 and 1981 were examined and compared to other shad populations. Mean fork lengths of adult shad captured in 1981 were 405-, 415- and 423-mm for age III, IV and V males;...

Masters Thesis
The development and maintenance of stream community structure and organization

Creator:

Wevers, Mary Jo

Abstract:

The goal of this study was to better understand stream communities through a perspective that might make their structure, organization, and development more understandable. This goal was approached through the following objectives: 1. To determine the assemblages of stream organisms and define subsystems within a stream community. 2. To explain...

Evaluation of combining ability in mosquitofish

Creator:

Pongthana, Nuanmanee

Abstract:

Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...

Evaluation of the sample ratio of sublegal to legal male crabs used to predict harvest of Dungeness crab (Cancer magister)

Creator:

Shaul, Warren

Abstract:

The sample ratio of sublegal to legal male crabs retained in crab pots was used in calculations to predict future harvest of Dungeness crabs, Cancer magister, along the Oregon coast. Accurate predictions by this method require a sample ratio representative of the population ratio. I sampled the Oregon Dungeness crab...

The fishery biology of the weathervane scallop [Pecten (Patinopecten) caurinus Gould, 1850] in Oregon coastal waters

Creator:

Nunez, Jose D.

Abstract:

Samples of weathervane scallops taken on Oregon Department of Fish and Wildlife cruises off Oregon waters during 1981-1982 were analyzed for a comparative growth study. No evidence of internal growth marks were found in the shell structure when analyzed by the acetate peel technique. Internal growth lines formed in the...

Mechanisms affecting the bioaccumulation of dietary quinoline by rainbow trout (Salmo gairdneri)

Creator:

Dauble, Dennis D.

Abstract:

Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...

Ecology of aquatic habitats associated with stream margins

Creator:

Moore, Kelly M. S.

Abstract:

The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

Trophic adaptations and relationships of rockfishes (Sebastes spp.) of Oregon

Creator:

Pequeño, Germán E.

Abstract:

A comparative analysis of structures related to capture and processing of food, in 624 specimens belonging to 31 species of Sebastes of Oregon was made. The structures studied were the following: the tooth-bearing bones (premaxillary, dentary, vomer, palatine); the maxillary, angular, articular, parasphenoid and glossohyal bones; the lower limb of...
