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....

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...

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),...

Biology of the Rex sole, Glyptocephalus zachirus Lockington, in waters off Oregon

Creator:: Hosie, Michael J.
Abstract:: Data are presented on the life history and population dynamics of rex sole (Glyptocephalus zachirus Lockington) collected from Oregon waters between September 1969 and October 1973. Length-weight relationships vary little between sexes or with time of year. Otolith annuli form primarily from January through May and were used for age...

Cryopreservation of Pacific salmon and steelhead trout sperm

Creator:: Ott, Alvin G.
Abstract:: Successful fertilization of fresh steelhead trout, pink salmon, kokanee, chum salmon, fall chinook salmon, and coho salmon eggs with cryopreserved sperm is reported in this thesis. A mean percent fertilization greater than 50 percent was achieved for all species tested except chum salmon. Differences in sperm viability from donor males...

Use of otoliths to differentiate juvenile steelhead trout from juvenile rainbow trout in the lower Deschutes River, Oregon

Creator:: Rybock, James Todd
Abstract:: Reported are results of a study of otolith nuclei as a means to separate juvenile steelhead trout (Salmo gairdneri) from juvenile rainbow trout (S. gairdneri) which co-exist in the lower Deschutes River, Oregon. An intensive recreational fishery necessitated development of a technique for separation so that the impact of the...
