Cryobiological investigations of the gametes of the Pacific oyster

Creator:

Staeger, William Henry

Resource Type:

Masters Thesis
Prediction of abundance of harvestable Dungeness crab (Cancer magister)

Creator:

Stefferud, Jerome Arthur

Abstract:

A method for predicting the harvest of commercial Dungeness crab (Cancer magister) one year in advance of the fishing season is described. The technique is based on the hypothesis that the relative abundance of sub-legal crabs one year is directly proportional to the harvest of legal crabs the following year....

Masters Thesis
Analysis of age determination methods for yellowtail rockfish, canary rockfish, and black rockfish off Oregon

Creator:

Six, Lawrence D.

Abstract:

Methods and utility of age determination of yellowtail rockfish (Sebastes flavidus), canary rockfish (Sebastes pinniger), and black rockfish (Sebastes melanops) collected off Oregon during 1972 to 1975 are discussed. Structures compared on the basis of the reproducibility of counts of annuli (consistency of readings) were the anal fin pterygiophore, opercle,...

Food habits and species composition of neritic reef fishes off Depoe Bay, Oregon

Creator:

Steiner, Richard George

Abstract:

The distribution and trophic ecology of neritic reef fishes was studied to provide biological information useful in conserving these stocks. Houk and line fishing was conducted from July 1976 to July 1977 on neritic reefs within 5 km of the Oregon coast adjacent to Depoe Bay. Sampling was designed to...

Comparative growth of juvenile Pacific oysters (Crassostrea gigas) fed unialgal vs. synthesized diets

Creator:

Toner, Margaret Ann

Abstract:

The results of research designed to develop a synthesized diet as a substitute or supplement to algae for culturing the Miyagi strain of juvenile Pacific oysters, Crassostrea gigas (Thunberg) are reported. The growth of juvenile Pacific oysters fed equal amounts (based on ash free dry weights [AFDW]) of algae (Pseudoisochrysis...

Masters Thesis
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...

Proposed minimum mesh size for managing the common Chilean hake fishery

Creator:

Pavez Carrera, Patricio B.

Abstract:

An analysis was conducted to estimate the minimum mesh size for managing the common Chilean hake (Merluccius gayi) fishery. Secondary objectives were to establish the selective relationship between mesh size and fish length, to examine growth patterns and related parameters, and to estimate the critical age (or optimum size) at...

Biology of the pile perch (Rhacochilus vacca)

Creator:

Wares, Paul Gordon

Abstract:

Data were gathered on the life history of the pile perch (Rhacochilus vacca) from Yaquina Bay, Oregon, between April, 1966, and July, 1967. Pile perch feed on the bottom and consume mostly molluscs, barnacles and decapod crustaceans. Food habits varied among seasons and locations within the bay, whereas the diet...

Life history of the snake prickleback Lumpenus sagitta Wilimovsky, 1956

Creator:

Tresierra-Aguilar, Alvaro

Abstract:

Data are presented on the life history of snake pricklebacks, Lumpenus sagitta, collected in Yaquina Bay, Oregon, from June 1977 to October 1978. Specimens were collected primarily by beach seine from four sampling sites in the bay. Snake pricklebacks feed on algae (mainly genus Enteromorpha), on polychaeta (mainly genus Neoamphitrite),...
