Recent advances in detection and control of infectious hematopoietic necrosis virus in aquaculture Recent advances in detection and control of infectious hematopoietic necrosis virus in aquaculture
Infectious hematopoietic necrosis (IHN) is one of the most important viral diseases of salmon and trout reared in culture. The disease remains untreatable with avoidance being the only control measure. Much has been learned about the chemical, physical, and serological characteristics of the rhabdovirus causing IHN, but critical gaps exist in our understanding of the biology of the virus...

Brood stock segregation of spring chinook salmon Oncorhynchus tshawytscha by use of the enzyme-linked immunosorbent assay (ELISA) and the fluorescent antibody technique (FAT) affects the prevalence and levels of Renibacterium salmoninarum in Brood stock segregation of spring chinook salmon Oncorhynchus tshawytscha by use of the enzyme-linked immunosorbent assay (ELISA) and the fluorescent antibody technique (FAT) affects the prevalence and levels of Renibacterium salmoninarum in
A study of the effect of maternal Renibacterium salmoninarum infection levels on the prevalence and levels of bacterial kidney disease (BKD) in progeny fish was conducted at a production salmon hatchery. A total of 302 mating pairs of spring chinook salmon Oncorhynchus tshawytscha was screened in August 1988 for R. salmoninarum by an enzyme-linked immunosorbent assay (ELISA). On the...

Infectious hematopoietic necrosis (IHN) and viral hemorrhagic septicemia (VHS): Detection of the trout antibodies to the causative viruses by means of plaque neutralization, immunofluorescence, and enzyme-linked immunosorbent assay Infectious hematopoietic necrosis (IHN) and viral hemorrhagic septicemia (VHS): Detection of the trout antibodies to the causative viruses by means of plaque neutralization, immunofluorescence, and enzyme-linked immunosorbent assay
Sera collected from cultured rainbow trout Oncorhynchus mykiss surviving outbreaks of infectious hematopoietic necrosis (IHN) or viral hemorrhagic septicemia (VHS) were examined for the presence of antibodies to both of the causative viruses, infectious hematopoietic necrosis virus (IHNV) and Egtved virus (viral hemorrhagic septicemia virus: VHSV). Sera were screened with three...

Effects of temperature on early-life-history stages of California halibut Paralichthys californicus Effects of temperature on early-life-history stages of California halibut Paralichthys californicus
- Laboratory experiments were conducted to determine how growth and survival of earlylife-history stages of California halibut Pamlichthys californicus are influenced by temperature, and how optimal temperature ranges may change with ontogeny. As halibut developed from eggs to juveniles, highest survival occurred at increasingly higher temperature ranges. Within tolerance limits, growth...

Rates of consumption of juvenile salmonids and alternative pray fish by northern squawfish, walleyes, smallmouth bass, and channel catfish in John Day Reservoir, Columbia River Rates of consumption of juvenile salmonids and alternative pray fish by northern squawfish, walleyes, smallmouth bass, and channel catfish in John Day Reservoir, Columbia River
Adult northern squawfish Ptychocheilus oregonensis, walleyes Stizostedion vitreum, smallmouth bass Micropterus dolomieu, and channel catfish Ictalurus punctatus were sampled from four regions of John Day Reservoir from April to August 1983–1986 to quantify their consumption of 13 species of prey fish, particularly seaward-migrating juvenile Pacific salmon and steelhead (Oncorhynchus spp...

Demonstration of the salmonid humoral response to Renibacterium salmoninarum using a monoclonal antibody against salmonid immunoglobulin Demonstration of the salmonid humoral response to Renibacterium salmoninarum using a monoclonal antibody against salmonid immunoglobulin
The specificity of the antibody response of salmonids to Renibacterium salmoninarum antigens was demonstrated by western blotting techniques that utilized a monoclonal antibody against salmonid immunoglobulin. In this study, the specificity of the response in immunized chinook salmon Oncorhynchus tshawytschawas compared with the response in naturally infected chinook salmon and coho...

Polymerase chain reaction (PCR) amplification of a nucleoprotein gene sequence of infectious hematopoietic necrosis virus Polymerase chain reaction (PCR) amplification of a nucleoprotein gene sequence of infectious hematopoietic necrosis virus
The polymerase chain reaction [PCR) was used to amplify a portion of the nucleoprotein [NI gene of infectious hematopoietic necrosis virus (IHNV). Using a published sequence for the Round Butte isolate of IHNV, a pair of PCR pnmers was synthesized that spanned a 252 nucleotide region of the N gene from residue 319 to residue 570 of the open reading frame. This region included a 30...

Pen rearing and imprinting of fall Chinook salmon. Annual report 1989 Pen rearing and imprinting of fall Chinook salmon. Annual report 1989
The goal of this project is to compare net-pen rearing methods to traditional hatchery methods of rearing upriver bright fall chinook salmon (Oncorhvnchus tshawvtscha). Fish were reared at several densities in net pens at three Columbia River backwater sites during 1984-1987, and in a barrier net at one site during 1984-1986; methods included both fed and unfed treatments. The purpose of...
