To understand how fish density and food availability affect habitat selection and growth of juvenile coho salmon (Oncorhynchus kisutch), we manipulated fish density (2-12 fish·m -2 ) and natural invertebrate drift (0.047- 0.99 mg·m -3 ) in 12 experimental stream channels constructed in a side-channel of Chapman Creek, British Columbia. Increased food resulted in increased growth of both dominant and subdominant fish and a shift to higher average focal velocities (from 6.5 to 8.4 cm·s -1 ) with…

Failure of physiological metrics to predict dominance in juvenile Pacific salmon (Oncorhynchus spp.): habitat effects on the allometry of growth in dominance hierarchies11Order of authors represents their contribution to the manuscript.

Outdoor semi-natural stream channels stocked with varying sizes of young of the year juvenile salmonids under high and low food rations are used to examine the mechanisms underlying variation in the benefits of dominance and demonstrate that inconsistencies in the apparent benefits are a logical outcome of the allometry of growth and differential energy intake among fish of different size in a dominance hierarchy.

Linking resource availability and habitat structure to stream organisms: an experimental and observational assessment

This work quantified the effects of natural variation in prey availability, PHS, and local fish density on summer growth of juvenile coho across multiple stream reaches and links the enhanced growth of coho to chironomid productivity.

Increasing Juvenile Coho Salmon Densities during Early Recolonization Have Not Affected Resident Coastal Cutthroat Trout Growth, Movement, or Survival

AbstractThe process of salmon colonization in the upper Cedar River and Rock Creek, Washington, following the installation of a fish ladder at Landsburg Diversion Dam in 2003, offered an opportunity

Prey abundance , channel structure and the allometry of growth rate potential for juvenile trout

The application of a drift-foraging bioenergetic model to evaluate the relative influence of prey abundance (invertebrate drift) and habitat (e.g. pool frequency) on habitat quality for

Prey abundance, channel structure and the allometry of growth rate potential for juvenile trout

Experiments and modelling indicated simultaneous limitation of fish growth by prey abundance and habitat, where depth and current velocity limit the volume of water and prey flowing through a fishs reactive field as well as swimming costs and prey capture success.

Oversummer growth and survival of juvenile coho salmon (Oncorhynchus kisutch) across a natural gradient of stream water temperature and prey availability: an in situ enclosure experiment

Conservation efforts for Pacific salmon (Oncorhynchus spp.) increasingly prioritize maintenance of cool water temperatures that protect all freshwater life stages. However, development of appropriate

Effects of habitat and internal prey subsidies on juvenile coho salmon growth: implications for stream productive capacity

Results indicate that, in addition to dependence on external terrestrial subsidies, streams with alternating slow and fast water sequences are also characterised by internal prey subsidies based on transport of drifting invertebrates from refuge habitats (high velocity riffles) to habitats more suitable for drift-feeding predators (e.g., pools), which may result in higher maximum fish growth in systems where internal subsidies are large.

A Climate-Mediated Shift in the Estuarine Habitat Mosaic Limits Prey Availability and Reduces Nursery Quality for Juvenile Salmon

The estuarine habitat mosaic supports the reproduction, growth, and survival of resident and migratory fish species by providing a diverse portfolio of unique habitats with varying physical and

Increased Population Density and Suppressed Prey Biomass: Relative Impacts on Juvenile Atlantic Salmon Growth

A large-scale field experiment was used to evaluate the relative effects of increased population density and suppressed prey biomass on the growth of juvenile Atlantic salmon Salmo salar.



Habitat factors affecting the abundance and distribution of juvenile cutthroat trout (Oncorhynchus clarki) and coho salmon (Oncorhynchus kisutch)

Abundance of larger cutthroat parr and pool habitat were positively correlated with large woody debris (LWD) within a subset of intermediate-gradient gravel-cobble streams, where pools appear to be limiting to larger cut throat parr abundance.

The mechanism of segregation between these two salmonids is clearly that of Nilsson's interactive type, which presumably functions to attenuate competition when streams are most likely to be resource limiting; typically, that is the late summer period of low flows and relatively high fish population densities.

Microhabitat‐Specific Foraging Behavior, Diet, and Growth of Juvenile Coho Salmon

Focal point velocity (FPV) differentiated specific microhabitats used by these two foraging behavior classes, and coho salmon in dominance hierarchies and nonhierarchical floaters exhibited two distinct types of forage behavior during observations made.
