Effects of size, age and photoperiod on hypoosmoregulation in brook trout, Salvelinus fontinalis
Brook trout (Salvelinus fontinalis) raised from eggs under two photoperiod and two feeding regimes were tested for physiological changes preparatory for transition from freshwater to seawater. Size, age, growth rate, photoperiod, and diel rhythms were examined for possible influences on plasma …

Spatial population dynamics of brook trout (Salvelinus fontinalis) in a central Appalachian watershed
… the spatial population dynamics of brook trout (Salvelinus fontinalis) in a central Appalachian watershed. The objectives of my research were: (1) identify factors that influence reproduction; (2) determine if factors that influence reproduction influence the distribution and abundance of …

WHAT PREDICTS TERRESTRIAL INVERTEBRATE SUBSIDY USE BY BROOK TROUT (SALVELINUS FONTINALIS) IN HEADWATER STREAMS?
… for trout, including eastern brook trout (Salvelinus fontinalis), we have limited understanding of what causes input and use of these subsidies to vary among streams. Among the watershed characteristics that may influence input and use of terrestrial invertebrates, I predicted that forest …

EFFECTS OF THERMAL STRESS ON SURVIVORSHIP OF BROOK TROUT (SALVELINUS FONTINALIS) IN ADIRONDACK LAKES
Brook trout (Salvelinus fontinalis) are common in waters ranging from the Appalachian Mountains to the Arctic Circle. These popular, coldwater sport fish face an uncertain fate in light of several climate change scenarios. Assessing the potential influence of variable temperature on brook trout …

Modeling Water Temperatures and Brook Trout (Salvelinus fontinalis) Growth Potential Within a Complex Appalachian Riverscape
Climate change is expected to cause air temperatures to increase 2-5°C in the Appalachians throughout the 21st century. These air temperature increases will cause water temperatures to increase, and may negatively effect cold and cool water fish species. Brook trout are an important game fish …

INDIVIDUAL VARIATION IN WINTER BROOK TROUT (SALVELINUS FONTINALIS) MOVEMENT IN A SMALL NORTHERN MICHIGAN STREAM
… and limited food availability. Brook trout (Salvelinus fontinalis) survival in winter is dependent on several factors including their condition after spawning in the fall and possibly their behavior in winter. Ice that forms during winter can potentially aid in survival by decreasing …

Factors influencing brook trout (Salvelinus fontinalis ) abundance in forested headwater streams with emphasis on fine sediment
… importance of fine sediment on wild brook trout (Salvelinus fontinalis) population size was assessed. Brook trout production in headwater streams was inversely proportional to substrate permeability in one of two years, suggesting substrate composition influenced production. Results suggest the …

Local and regional controls of brook trout (Salvelinus fontinalis) metapopulation dynamics within a complex Appalachian riverscape
Brook trout have recently become a species of conservation focus due to their unique spatial structure and restricted thermal requirements. These life history characteristics make brook trout particularly vulnerable to major biodiversity threats, such as climate change and habitat loss. For …

Effects of annual thermal regime on growth trajectories of native age-0 brook trout (Salvelinus Fontinalis)
… novel threat to populations of brook trout (<em>Salvelinus fontinalis</em>), and much uncertainty remains about the potential of these populations to acclimate, adapt, or compensate for such changes. Brook trout are considered stenothermal, with a thermal preference of 14°C to 18°C, and a …

The Reproductive Physiology Of Brook Charr (salvelinus Fontinalis, Mitchill) From Neutral And Acidic Lakes In Northern Ontario
… that the reproductive physiology of brook charr (Salvelinus fontinalis) differed between acidic and neutral lakes. Charr were collected from neutral (pH > 6.5) and acidic (pH < 6.5) lakes in the Sault Ste Marie and Blind River areas of Northern Ontario from June to November of 1981 to 1983. Female …

Effects of turbidity on the foraging abilities of brook trout (Salvelinus fontinalis) and smallmouth bass (Micropterus dolomieu)
… cold and warm water stream habitas, brook trout (Salvelinus fontinalis ) and small mouth bass (Micropterus dolomieu).;This research was conducted in an artificial stream at West Virginia University and consisted of determination of effects of turbidity on reactive distance and foraging success of …

Evaluation of Brook Trout (Salvelinus fontinalis) Introductions and Re-introductions Into Four Virginia Blue Ridge Mountain Streams
Approximately 100 brook trout were transplanted into each of four Virginia streams in September 2008. Garth Run and Kinsey Run were re-introductions, and Wildcat Hollow and Sweet Run were new introductions. Single pass electrofishing (EF) surveys were conducted with a backpack electrofisher five …

EFFECTS OF WINTER AND SUMMER THERMAL VARIABILITY REGIMES ON GROWTH AND METABOLISM IN BROOK TROUT (Salvelinus fontinalis)
<p>Brook trout (<em>Salvelinus fontinalis</em>) is a cold-water species with a narrow range of thermal tolerance. Climate change projections show that in addition to increases in average temperatures worldwide, daily thermal variability is increasing. Such conditions could prove challenging for …

Production of brook trout (Salvelinus fontinalis) in four headwater streams in the James River Basin of Virginia and West Virginia
The production of brook trout (<i>Salvelinus fontinalis</i>) in four headwater streams was studied with respect to natural variation in production and turnover ratios, contribution by age group and time of year, and correlations of physical and chemical variables with production. Lick Run and …
