The purpose of this report is to describe a large tumor complex that was found protruding into the pericardial cavity of a single Ostrea lurida from Yaquina Bay, Oregon.
A cellular proliferative disorder that superficially resembles mammalian leukemia has been found in several species of pelecypod mollusks from Yaquina Bay, Oreg. This paper reviews the history of the disease, its cytomorphological and histopathological characteristics, molluscan oncology, and cell renewal and describes current research on the neoplastic disease of bivalve...
An article detailing the intense storms on the Pacific Northwest coast in the last 10 days of October 1977. Reprinted from Mariners Weather Log 22 (2).
The feeding habits of the Dover sole and rex sole (mainly juveniles) and of slender sole and Pacific sanddab were investigated at seven stations on the continental shelf off central Oregon. Dover sole had a catholic diet, feeding on a large variety of infaunal and epifaunal invertebrates. The composition of...
Pandalis jordani Rathbun, like many other species of pandalid shrimps, undergo regular diel changes in their vertical distribution (Tegelberg and Smith 1957; Alverson et al. 1960; Pearcy 1970, 1972; Robinson in press). Little is known, however, about the vertical distribution and diel migrations of larval and juvenile shrimp, or at...
Catch data for albacore troll boats were collected from fishermen's logbooks and from dockside
interviews during the 1968, 1969, and 1970 seasons. Fishing powers of these boats were calculated and used to determine the 10 most successful and 10 least successful fishermen (highliners and lowliners, respectively) who fished off Oregon...
This paper describes a method for measuring nearshore ocean wave characteristics with a land-based, long-period vertical seismometer. The wavemeter system has proven to be highly reliable and produces continuous wave observations at low cost. It is now operational at six Coast Guard stations along the Oregon and Washington coasts; data...
Dover and rex sole larvae attain an exceptionally large size and have a long pelagic life. Dover sole larvae (9-65 mm standard length) were collected in mid-water trawls and plankton nets during all months of the year. Judging from growth of larvae and occurrence in bottom trawls of recently metamorphosed...
