This paper represents a comprehensive test of the hypothesis that aggression in salmonids increases with the duration of stream residence. The intraspecific aggression of eleven juvenile salmonids was compared with their normal duration of stream residence. Salmonids maintained in 1 metre tanks and observed over two days could be separated into four groups based on statistical differences between the frequencies of aggressive behaviour. Non-anadromous Salvelinus fontinalis showed the highest… 
Variation in growth and aggression of juvenile brown trout (Salmo trutta) from upstream and downstream reaches of the same river
TLDR
Differences in the allometric relationship between growth rate and fish size and in the levels of aggressiveness appear to be related to the failure to form dominance hierarchies among fish from the downstream reach, a fixed behavioural trait most likely related to prior experience of crowding or different genetic backgrounds.
Non–indigenous brook trout and the demise of Pacific salmon: a forgotten threat?
TLDR
The results emphasize that non–indigenous species are present and may have a dramatic impact, even in remote regions that otherwise appear pristine; however, many of the populations investigated occur in wilderness areas, their habitat has been considered pristine.
Comparing competitive ability and associated metabolic traits between a resident and migratory population of bull trout against a non-native species
TLDR
Results suggest native bull trout have population-level variation in competitive ability against a non-native species and such competitive ability is positively associated with metabolism and migratory life history.
Behavioural syndromes in juvenile brown trout (Salmo trutta); life history, family variation and performance in the wild
TLDR
Offspring boldness was not affected by paternal migratory life history, but significant effects of the female parent suggested maternal and/or genetic effects, and female parent effects on variation in fry size persisted over the first growth period in the wild.
Interspecific Effects of Artifically Propagated Fish: an Additional Conservation Risk for Salmon
TLDR
It is demonstrated that the survival of wild chinook salmon is negatively associated with hatchery releases of steelhead, and that the potential interspecific impact of hatcheries must be considered as agencies begin the process of hatchery reform.
Spatial and temporal patterns of vertical distribution for three planktivorous fishes in Lake Washington
TLDR
Variation in the vertical distribution of three sympatric planktivores is illustrated and offers broader implications for the DVM phenomenon and applied lake ecology.
Influence of species, size and relative abundance on the outcomes of competitive interactions between brook trout and juvenile coho salmon
TLDR
It is thought it is unlikely that competition from brook trout will disrupt Elwha River recolonization by coho salmon, because coho Salmon experienced more intra- than inter-specific competition and that brook Trout do not pose a substantial challenge.
Territorial Aggression Increases Along an Urban Gradient in Resident But Not Migratory Song Sparrows
During the breeding season, birds behave more aggressively toward rivals to maintain and defend territories. Resident birds are thought to be more aggressive than migratory birds because they need to
Redside shiner (Richardsonius balteatus) shoals provide a behavioral competitive refuge for subordinate juvenile steelhead trout (Oncorhynchus mykiss)
TLDR
In both experiments, the smallest steelhead frequently took refuge within the shiner group, thereby avoiding attack by dominant steelhead, and this phenomenon was termed a behavioural competitive refuge.
Physiological and genetic basis for variation in migratory behavior in the three-spined stickleback, Gasterosteus aculeatus
TLDR
The three-spined stickleback Gasterosteus aculeatus (Linnaeus 1758) is a good model system for elucidation of the genetic basis for variation in migratory behaviors and other physiological changes associated with migration and genetic and genomic tools are now available for studying this species.

Territorial Behaviour of Juvenile Atlantic Salmon (Salmo Salar L.)
TLDR
The territories of young salmon appear to be primarily feeding territories, and the behaviour associated with their maintenance is important for optimum growth and survival and for maintaining position for long periods in fast flowing streams.
The Behaviour of Juvenile Pacific Salmon, with Particular Reference to the Sockeye (Oncorhynchus nerka)
TLDR
It is suggested that sockeye fry, emerging from cover as the light intensity falls are displaced downstream after dark, and that the smolt exodus is due to heightened general activity, both day and night, associated with strong response to current.
Inherited differences in agonistic behavior between two populations of coho salmon
TLDR
A genetic basis for the observed behavioral differences in the laboratory-reared fish is suggested, and it is suggested that these differences also are characteristic of the two wild populations.
Aggressiveness and foraging mode of young-of-the-year brook charr, Salvelinus fontinalis (Pisces, Salmonidae)
TLDR
Simple graphical models are used, based on encounter rate with drift and the theory of economic defendability, to predict qualitative changes in the aggressiveness and mobility of brook charr in relation to current velocity, and results are generally consistent with the simple graphical models.
Genetic relationships among landlocked, resident, and anadromous Brown Trout, Salmo trutta L.
TLDR
Brown Trout were compared genetically with landlocked populations in the same drainage system in western Norway, showing larger genetic differentiation between localities than between coexisting life-history types that differ in morphology and ecology.
Aggressiveness and the Foraging Behaviour of Young-of-the-Year Brook Charr (Salvelinus fontinalis)
Individual young-of-the-year brook charr (Salvelinus fontinalis) were observed in the field to relate their aggressiveness to their body size, the size and quality of their foraging site, and their

TLDR
A model is developed to predict potential net energy gain for salmonids in streams from characteristics of water velocity and invertebrate drift, and coho salmon always achieved higher specific growth rates than either brook trout or brown trout in concurrent experiments, and maintained growth to lower resource thresholds.
