Genetic characterization of Polish cultured brook trout, Salvelinus fontinalis (Mitchill), based on microsatellite DNA analysis

Usefulness of heterologous microsatellites obtained from brook charr, Salvelinus fontinalis Mitchill, in other Salvelinus species.

Exercise training in skeletal muscle of brook trout (Salvelinus fontinalis).

1. The differentiation of myotomal muscles in the brook trout (Salvelinus fontinalis Mitchill) has been investigated using p-phenylene diamine stained semi-thin sections and cytochemical and quantitative determinations of enzyme activities. 2. Evidence is presented that the range of fibre size in white muscle represents stages in growth rather than distinct fibre types. 3. Electromyography show...

The rise and fall of isolation by distance in the anadromous brook charr (Salvelinus fontinalis Mitchill).

Geographic patterns of genetic diversity depend on a species' demographic properties in a given habitat, which may change over time. The rates at which patterns of diversity respond to changes in demographic properties and approach equilibrium are therefore pivotal in our understanding of spatial patterns of diversity. The brook charr Salvelinus fontinalis is a coastal fish exhibiting limited m...

Development of temperature correction equations for bioelectrical impedance analysis models for brook trout Salvelinus fontinalis.

The objective of this study was to establish the relationships between bioelectrical impedance analysis (BIA) measures (resistance and reactance) and temperature and to determine if corrections improve BIA models for brook trout Salvelinus fontinalis when used over a wide range of temperatures. Both resistance and reactance significantly decreased as temperature increased. Application of temper...

Kinship analysis of brook trout Salvelinus fontinalis during their breeding migration.

Microsatellite markers were used to test whether groups of pre-spawning adult brook trout Salvelinus fontinalis from the same population and captured at the same location during their breeding migration comprised kin. Only weak evidence for kin associations was found at the onset of breeding: the proportion of kin captured at the same location was low and similar to the proportion found across ...
