Variation in feeding, aggression, and position choice between hatchery and wild cutthroat trout in an artificial stream Variation in feeding, aggression, and position choice between hatchery and wild cutthroat trout in an artificial stream
I compared feeding, aggressive behavior, and spatial distribution of differently ranked individuals of hatchery and wild coastal cutthroat trout Oncorhynchus clarki clarki in an artificial stream. Both hatchery and wild groups established stable dominance hierarchies that seemed to be based on size differences. Hatchery and wild fish within a hierarchical rank fed at similar rates...

Physiological response of largemouth bass to angling stress Physiological response of largemouth bass to angling stress
The physiological effects of catch-and-release fishing on largemouth bass Micropterus salmoides from Lake Powell and Mantua Reservoir, Utah, were evaluated, and an estimate of the time needed for recovery from hooking stress was obtained. Fatigue in Lake Powell fish, as indicated by elevated blood lactate, was directly proportional to hooking time (1–5 min) and water temperature, but...

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...

Heterosis and outbreeding depression: A multi-locus model and an application to salmon production Heterosis and outbreeding depression: A multi-locus model and an application to salmon production
Both artificial propagation and efforts to preserve or augment natural populations sometimes involve, wittingly or unwittingly, the mixing of different gene pools. The advantages of such mixing vis-à-vis the alleviation of inbreeding depression are well known. Acknowledged, but less well understood, are the complications posed by outbreeding depression. This paper derives a simple model...

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...
