Size classes, population structure, growth, sex ratio, and size and age at maturity of Chionoecetes tanneri Rathbun (Brachyura:Majidae) off the Oregon coast

Creator:: Tester, Patricia A.
Abstract:: During eleven cruises conducted off the Oregon continental slope from April 1973 to March 1975, approximately 1600 specimens of the majid crab Chionoecetes tanneri Rathbun were collected. A time sequence of size frequency histograms and bivariate plots of allometric measurements were used to determine size classes, population structure, growth and...

Dynamics of crab larvae (Anomura, Brachyura) off the central Oregon coast, 1969-1971

Creator:: Lough, Robert Gregory, 1943-
Abstract:: Bimonthly plankton samples were collected from 1969 through 1971 along a transect off the central Oregon continental shelf (44° 39. l'N) to document the species of crab larvae present, their seasonality, and their onshore-offshore distribution in relation to seasonal changes in oceanographic conditions. A comprehensive key with plates is given...

The role of stridulation in the behavior of the shore crab Hemigrapsus oregonensis

Creator:: Guin, Marilyn P.
Abstract:: The claw shuddering display of the shore crab Hemigrapsus oregonensis was explored with acoustic and behavioral observations. Male H. oreqonensis stridulate during claw shuddering display. The stridulatory apparatus is present only on the males. The acoustic signal was of brief duration, showed a general pattern of sound bursts, but varied...

The fishery and biology of the Dungeness crab (Cancer magister Dana) in Oregon waters

Creator:: Waldron, Kenneth D. and Oregon. Fish Commission
Abstract:: Results of studies beginning in 1947 on the biology of the Dungeness crab (Cancer magister) in Oregon coastal waters are reported. A review is made of the history of the fishery with regard to trend of the catch by magnitude, area, and season; the development and conduct of the fishery...

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...

Summary of the 1965-66 crab season sampling and projected landings

Creator:: Snow, C. Dale and Oregon. Fish Commission. Shellfish Investigations
Abstract:: "The Shellfish Investigation samples the crab catch along the Oregon coast each year for shell condition as an index to meat yield and suitability of season opening dates. In addition to sampling for condition, a number of animals are sampled for width frequencies to determine the mean size of crabs...

Report on meeting with crab fishermen : Astoria, December 21, 1948

Creator:: Tollefson, Roger, Marriage, Lowell D., and Oregon Fish Commission
Abstract:: In mid-December, 1948, during the time the crab season was closed in State waters, a boat caught crabs outside the entrance to the Columbia River, which was outside the three-mile jurisdictional limit. Because "one man was already fishing," the crab fleet members began to complain and threaten to fish before...

Controlled rearing of dungeness crab larvae and the influence of environmental conditions on their survival : July 1, 1966 to June 30, 1967

Creator:: Reed, Paul H. and Oregon. Fish Commission
Abstract:: "During the first year of the program successful culture methods were developed for rearing Dungeness crab larvae (Reed 1966). The purpose of the second years work was to define the effects of wide ranges of temperature and salinity on survival and growth of Dungeness crab larvae." (p.1) Includes charts, graphs...

Controlled rearing of dungeness crab larvae and the influence of environmental conditions on their survival, 1965/1966

Creator:: Reed, Paul H. and Oregon. Fish Commission
Abstract:: "Construction of a larval rearing system and development of rearing techniques for Dungeness crab larvae were the objectives of the first year's program. Preliminary work involved a literature search, consultation with biologists involved with molluscan and crustacean larval culture, and the design of a rearing system based on the success...

Creator:: Reed, Paul H. and Oregon. Fish Commission
Abstract:: "Culture methods for Dungeness crab larvae and the effects of temperature and salinity on larval survival and growth were covered in previous progress reports (Reed, 1966 and 1967). This report covers studies conducted from July 1,1967, through June 30, 1968 to determine the effects of various laboratory diets and diet...
