Preliminary characterization of a virus causing infectious anemia among stocks of salmonid fish in the western United States
Since 1982, anemias occurring in stocks of yearling coho (Oncorhynchus kisutch) and chinook salmon (Oncorhynchus tshawytscha) have been associated with serious losses at hatcheries in the Pacific Northwest, USA. The anemia is often accompanied by infections with external fungus (e.g. Saprolegnia) or the bacterial pathogens Cytophaga psychrophila or Renibacterium salmoninarum (Holt and Rohovec 1984

Quantitative petrographic analysis of Desmoinesian sandstones from Oklahoma
Desmoinesian sandstones from the northern Oklahoma platform and the Anadarko, Arkoma, and Ardmore basins record a complex interaction between mid-Pennsylvanian source-area tectonism and cyclic sedimentation patterns associated with numerous transgressions and regressions. Framework-grain summaries for 50 thin sections from sandstones of the Krebs, Cabaniss, and Marmaton Groups and their surface an

Response of salmonid fish to artificial infection with chum salmon virus
In the fall of 1978, a reovirus was isolated from normal-appearing adult chum salmon (Oncorhynchus keta) returning to the Tokushibetsu Hatchery in Hokkaido, Japan (Winton et al 1981). The chum salmon virus (CSW) was recovered in the chinook salmon (Oncorhynchus tshawytscha) embryo cell line (CHSE-214) where it replicated at 15-20 C, producing foci of syncytia in the monolayer.
