Index of predation on juvenile salmonids by northern squawfish in the lower and middle Columbia River and in the lower Snake River Index of predation on juvenile salmonids by northern squawfish in the lower and middle Columbia River and in the lower Snake River
We developed a predation index to describe the relative magnitude of predation on juvenile salmonids by northern squawfish Ptychocheilus oregonensis throughout the lower and middle Columbia River and lower Snake River. The predation index was the product of an abundance index and a consumption index. We evaluated various catch indices and found that catch per unit effort best reflected...

Prerelease disease treatment with potassium permanganate for Fall Chinook salmon smolts Prerelease disease treatment with potassium permanganate for Fall Chinook salmon smolts
Standard potassium permanganate treatment (2 mg KMnO4/L freshwater for 1 h on three consecutive days) was applied to presmolts (parr) and smolts of fall chinook salmon (Oncorhynchus tshawytscha). Smoltification was determined by gill Na+,K+-ATPase activity. Treatments were conducted 73, 59, 45, 31, 16, and 2 d prior to full-strength seawater entry in aquaria. Potassium permanganate did...

Characterization of a rhabdovirus isolated from carpione Salmo trutta carpio in Italy Characterization of a rhabdovirus isolated from carpione Salmo trutta carpio in Italy
A virus, strain 583, was isolated from carpione Salmo trutta carpio fry exhibiting high mortality. The virus was not neutralized by rabbit antisera against the fish rhabdoviruses viral haemorrhagic septicaemia virus (VHSV), infectious hematopoietic necrosis virus, eel rhabdovirus European X, spring viraemia of carp virus or pike fry rhabdovirus, or against the birnavirus infectious...

Viral hemorrhagic septicemia virus in North America Viral hemorrhagic septicemia virus in North America
The first detections of viral hemorrhagic septicemia virus (VHSV) in North America were in Washington State from adult coho (Oncorhynchus kisutch) and chinook (O. tshawytscha) salmon in 1988. Subsequently, VHSV was isolated from adult coho salmon returning to hatcheries in the Pacific Northwest in 1989, 1991 and 1994. These isolates represented a strain of VHSV that was genetically...

Heterogeneity in pepper isolates of cucumber mosaic virus Heterogeneity in pepper isolates of cucumber mosaic virus
Twenty-four cucumber mosaic cucumovirus (CMV) field isolates from pepper crops in Cali-fornia were characterized and compared by nucleic acid hybridization subgrouping, virion electrophoresis, and biological effects in several hosts. Isolates, belonging to subgroup I or subgroup II, were found that induced severe symptoms in mechanically inoculated bell pep-pers. Only two isolates, both...

Differentiation of Colletotrichum species responsible for anthracnose of strawberry by arbitrarily primed PCR Differentiation of Colletotrichum species responsible for anthracnose of strawberry by arbitrarily primed PCR
A collection of 39 isolates of Colletotrichum acutatum, C. fragariae and C. gloeosporioides, which cause anthracnose on strawberry, was grouped into species based on the arbitrarily primed polymerase chain reaction (ap-PCR). All isolates used had previously been identified according to classical taxonomic morphology. Ap-PCR amplification of genomic DNA using four different primers...

Endangered cui-ui of Pyramid Lake, Nevada Endangered cui-ui of Pyramid Lake, Nevada
Cui-ui (Chasmistes cujus) is a large plankton-feeding fish that only occurs in Pyramid Lake, Nevada. It was put on the federal endangered list in 1967 based on declining population and absence of reproduction. A lake dweller, cui-ui is a stream spawner. Most of this century, this sucker species was unable to access the Truckee River, Pyramid Lake's only perennial tributary, to reproduce...
